stephentuso / welcome-android Goto Github PK

In the following code, I got two errors

public class MyWelcomeActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my_welcome);
    }


    @Override
    protected WelcomeScreenConfiguration configuration() {
        return new WelcomeScreenBuilder(this)
                .theme(R.style.WelcomeScreenTheme_Light)
                .defaultBackgroundColor(new BackgroundColor(Color.RED))
                .titlePage(R.drawable.logotest, "Title")
                .basicPage(R.drawable.photo1test, "Header", "More text.", new BackgroundColor(Color.GREEN));
                .basicPage(R.drawable.photo2test, "Lorem ipsum", "dolor sit amet.")
                .swipeToDismiss(true)
                .build();
    }
}

Error 1: There is no override of configuration()
Error 2: The .basicPage that has a background color was expecting an integer, but the wrapper of background color does not return such an integer.

What can I do?
Thanks!

we can't change the bottom bar background for each page. I used FullscreenParallaxPage with customize layout, but botttom bar can't change according to color of current page.

Currently once a page fragment is created, it won't be GCd until the activity closes. Ideally, only the current and immediately adjacent pages would be held on to

Hi,

I'm getting the following error while including your library:

Attribute application@allowBackup value=(false) from AndroidManifest.xml:13:9-36
    is also present at [com.stephentuso:welcome:0.7.1] AndroidManifest.xml:12:9-35 value=(true).
    Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:11:5-79:19 to override.
See http://g.co/androidstudio/manifest-merger for more information about the manifest merger.
:app:processDebugManifest FAILED
Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed with multiple errors, see logs

As adviced by the error, overriding works, but anyway I think you should remove android:allowBackup="true" from the library manifest. since I think it is useless for a library project.

Thanks & Regards

Swipe to dismiss does not work when the layout is RTL

Hi
at first i thank you for your good library...
i use it with the default configuration you explain at introduction page of Github...
but when i install my app in mobile i see welcome screen one time, and on another use this page is invisible...
i want to see it every time my application is started not only in first use...

best thanks...

Hi,

What an awesome project!

I'm using your library to create an instructional slide show, rather than using it as a conventional welcome screen. Therefore, I'd like to have persistently available back and forward buttons, and discard the skip and done buttons.

1. Is it possible to have a persistent back button, that can be used in a similar fashion to the forward button, allowing the user to navigate using a back and forward button in addition to swiping.
2. How do i allow for the activity to be "relaunched" after it has been "completed" by the user?
3. Is it possible to include a actionbar, allowing the user to navigate to the parent activity?

Thanks in advance!

Here is logcat

i attached the screenshot of class and line no where it show the error.

I configured my WelcomeActivity following the read me guide but on execution my project crashes with the following message in Logcat:

No field view_pager of type I in class com/stephentuso/welcome/R.id; or its superclasses

I'm using the Android Emulator (API 24) for testing.

Is this a known issue? If so, are there any workarounds?

Hello and thanks for this awesome library.

I want to know if there's an inbuilt method to clear the welcome activity's preferences from any where in the code. I am implementing a reset button which clears the app's shared preferences and restarts the application. But on restarting, the welcome activity is still not shown which means it's own preferences were still intact.

Thanks once again.

How to change action of button done and exit ? thanks

The theme for the activity should be set in androidmanifest.xml rather than using WelcomeScreenBuilder

Now that in 1.0 the builder page method only takes a WelcomePage, rather than a bunch of different methods and parameters for each page type, it is much easier to add some more options. For the basic page, title page, and parallax page, I'm thinking the layout options would be the current (text on bottom, large image), text on top with large image, and more centered text with smaller image. Each class could then have a layout method that used an enum perhaps, and then a different layout file would be used based on that.

It's more a question than an issue.

I have this case: I created a welcome screen for my app, it's like my app's overview. But I can show this screen again from a menu. Reading another issue listed, I can start the activity from my SplashScreen, and start my home screen when done.

But, when I forced show the WelcomeScreen, there is no way to know if it's forced show or not, and the activity was started again.

I achieved a way to do this, creating a shared preference and ignore the startActivity if it has the key, but I would like to know if is it possible to have a key or a property that flags the activity was forced shown or not.

The code from my done button (get the reference from yours button using butterknife)

@OnClick(com.stephentuso.welcome.R.id.wel_button_done)
    public void mButtonDoneOnClickListener() {
        completeWelcomeScreen();

        if(!PreferenceManager.getDefaultSharedPreferences(MyWelcomeActivity.this).contains("intro"))
            startActivity(new Intent(MyWelcomeActivity.this, MainActivity.class));
    }

How to change text(skip) and indicator color in bottom layout? (By default just White Color) Thanks

I'm using welcome-android to create a slideshow gathering all the things my wife loves.
There are 36 pages, and I'm using almost all page example model included in welcome-android.
Until now, I used only photo.png provided in welcome-android https://github.com/stephentuso/welcome-android/blob/master/sample/src/main/res/drawable/photo.png, and I could see the whole slideshow without any issue.

Now, I replace "photo.png" with resized photos/clipart (500x500px & transparent background), and here is my problem/issue : App crashes after the 16th screen.

Here is my logcat : http://pastebin.com/LfDkGTag

Calling defaultBackgroundColor with a resource id has no effect

I was looking up some documentation related to android testing and it was advised that if I am testing a library, I should open a new project and test the methods. Could that be incorporated into the github repo ? If so, how?

Thanks!

Hello Stephen Tuso.
Thank you for your awesome App.

The "issue" i want to report, is that all displayed text on the welcome screens is hard coded

Ex: https://github.com/stephentuso/welcome-android/blob/master/sample/src/main/java/com/stephentuso/welcomeexample/DefaultWelcomeActivity.java

.page(new TitlePage(R.drawable.ic_image_white, "Default Welcome Screen"))
                .page(new BasicPage(R.drawable.ic_style_white, "Default style", "No custom styles are applied to this welcome screen"))
.page(new BasicPage(R.drawable.ic_image_white, "Default properties", "No properties were set on the WelcomeScreenBuilder"))

So, I found how to expose these hard coded strings https://github.com/KowalskiOmniROM/welcome-android/blob/master/sample/src/main/java/com/stephentuso/welcomeexample/DefaultWelcomeActivity.java

Due of my lack of knowledge, I didn't figure how to expose:
https://github.com/stephentuso/welcome-android/blob/master/sample/src/main/java/com/stephentuso/welcomeexample/fragment/ExampleFragment.java
Toast.makeText(getContext(), "Button clicked in custom fragment", Toast.LENGTH_SHORT).show();

Anyway, thank you for your great work.
Have a nice day.

I am not sure how I will help you to reproduce it but I have support library version 25.1.0 and welcome:1.1.0.

I initially get this warning/error from Android Studio:

This crashed the preview with a stracktrace:

When I remove the compile 'com.stephentuso:welcome:1.1.0' dependency from my build.gradle, everything is working again.

Is there any way we can bump up preference-v7 version to 25.1.0. I feel like that might fix the issue.

My apologies if this is not this libraries problem but as removing this dependency was a direct solution to the preview crashing, I thought I should report it here.

Love your work and appreciate all the hard work btw 👍.

Hi. Thanks for great work.

I have a custom finish button which I want to save a bunch of strings to SharedPreferences before calling finish but for some reason it does not end up saving.

It'll save if I create an intent to launch another activity, however, with new WelcomeFinisher(WelcomeFragment_2.this).finish(); nothing gets saved.

I've tried SharedPreferece editor .commit(), adding a countdowntimer and also post handler but nothing seems to work for me.

`

First of all, congratulations for making this excellent library. I would only like to ask if you could point any sample of code where you shows how can the done button's text be changed.

I saw this answer (#10) but I didn't figured out how the .theme works, and where should I place it. Thanks!

There is a blank screen that appears to be like the app is launched but hasn't any UI to display. Pressing back dismisses the app and one can navigate normally with device otherwise everything appears like the device has frozen, which is not the case but that there's an app running with no interface and appears transparent to the device screen. This happens when the app is launched the subsequent times from the very first time it is installed and launched. Please we need this issue fixed asap.

hi, i am using your library it is working fine but i when user reaches to the last page i want to change the button text from "DONE" to "OK", i am not able to find any method in your library , please anyone guide me?

How could I change Description and Title TextSize? cause using different typefaces changes font size appearance.

Hey how I can change the text from buttons "done" and "skip"
I not found method for do this, please help me

Hi,

What would be the best way to add background image to each page instead of background color?

-- Veikko

• Add prefixes to resources to avoid naming conflicts with clients, make some resources private
• Remove deprecated methods
• WelcomeScreenConfiguration and WelcomeScreenBuilder could be combined.
• Are WelcomePage.OnChangeListener and OnWelcomeScreenPageChangeListener both needed? Yes
• More refactoring?

When I click on Back button at that time welcome slider finish and next screen open.Not app close.

i need to implemet this on fragment, but i cant found example to implement this

I was trying to write a unit test for welcome screen, and before I do that, I try to make a welcome screen with the library. I was trying to change the code in the configuration as follow:

new WelcomeScreenBuilder(this).defaultBackgroundColor(Color.RED)

An error popped up:"Expect Resource of type color", even though Color is an inbuilt library in android studio. Maybe we can overload the function so that the Colo library can also be accepted.

swipeToDismiss(true) does not work if phone language set to RTL languages such as Arabic, Persian, ...
but once language changes to English swipeToDismiss(true) works as it should be.

After downloading the source and put it into Android studio i got that error.

// Thank you

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 26.0.0-alpha1, 25.3.1. Examples include com.android.support:animated-vector-drawable:26.0.0-alpha1 and com.android.support:preference-v7:25.3.1 less... (Ctrl+F1)
There are some combinations of libraries, or tools and libraries, that are incompatible, or can lead to bugs. One such incompatibility is compiling with a version of the Android support libraries that is not the latest version (or in particular, a version lower than your targetSdkVersion.)

like first page title color red and second green

BasicPage has method for changing the header color

headerColor

for each page but it did not see method for changing the description text for each page. I know I can do via custom fragment however, it would be useful to be add to the library.

Hi, thank you for this great library. I've been using it and everything is fine and the welcome screen looks perfect, the only thing I don't understand is how to go back to the main layout after showing the welcome screen.

My MainActivity:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        sampleWelcomeScreen = new WelcomeHelper(this, WelcomeActivity.class);
        sampleWelcomeScreen.show(savedInstanceState);
}

@Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        sampleWelcomeScreen.onSaveInstanceState(outState);
    }

// If this method should display toast at the end or cancel the welcome screen, it is not doing so
@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_WELCOME_SCREEN_RESULT) {

            if (resultCode == RESULT_OK) {
                Toast.makeText(getApplicationContext(), "Completed (RESULT_OK)", Toast.LENGTH_SHORT).show();
//this Toast is not displayed
            } else if (resultCode == RESULT_CANCELED) {
                Toast.makeText(getApplicationContext(), "Canceled (RESULT_CANCELED)", Toast.LENGTH_SHORT).show();
//this Toast is not displayed
            }
        }
    }

I want you to end or click on "done" to display activity_main again

Just by following your basic tutorial of the README.md the app is crashing when started.

Caused by: android.view.InflateException: Binary XML file line #30: Binary XML file line #30: You must supply a layout_height attribute.

Seems like inflating R.layout.wel_activity_welcome is not working. When I look at the code there is no height attribute for the View at line #30

Hi. thanks for great work.
How can i show welcome Activity only in first run and show MainActivity in next runs.

Finish PreferenceWelcomeFragment. It should probably extend PreferenceFragmentCompat and allow clients to inflate preferences from xml.

hey! this library is really great.. i have been using it lately and i need to override done button, could you help me if there is any possible solution to it.

I tried to do it like this
public class MyWelcomeActivity extends WelcomeActivity
{
@Override protected WelcomeScreenConfiguration configuration()

{ DoneButton done = new DoneButton(findViewById(R.id.button_done)); done.setOnClickListener(new View.OnClickListener() { @Override
public void onClick(View v) { Log.e("SahajLOG", "Done Button Called "); completeWelcomeScreen(); } });
return new WelcomeScreenBuilder(this) .theme(R.style.CustomWelcomeScreenTheme) .defaultTitleTypefacePath("Montserrat-Bold.ttf") .defaultHeaderTypefacePath("Montserrat-Bold.ttf") .titlePage(R.drawable.traffic_sign, "Welcome", R.color.SwipeScreen1) .page(new WelcomeFragmentHolder() { @Override protected android.support.v4.app.Fragment fragment() { return new WelcomeProfileFillFragment(); }
}, R.color.material_green) //.swipeToDismiss(true) .build(); }
}

I tried to find a configuration option to set the alignment but I was unable to find it. How do I set the text align to center. By default the text aligns to the left

public class WelcomeScreenActivity extends WelcomeActivity {
    @Override
    protected WelcomeConfiguration configuration() {
        return new WelcomeConfiguration.Builder(this)
                .defaultTitleTypefacePath("Montserrat-Bold.ttf")
                .defaultHeaderTypefacePath("Montserrat-Bold.ttf")

                .page(new BasicPage(R.drawable.ic_front_desk_white,
                        "Welcome",
                        "An Android library for onboarding, instructional screens, and more")
                        .background(R.color.orange_background)
                )

                .page(new BasicPage(R.drawable.ic_thumb_up_white,
                        "Simple to use",
                        "Add a welcome screen to your app with only a few lines of code.")
                        .background(R.color.red_background)
                )

                .page(new ParallaxPage(R.layout.parallax_example,
                        "Easy parallax",
                        "Supply a layout and parallax effects will automatically be applied")
                        .lastParallaxFactor(2f)
                        .background(R.color.purple_background)
                )

                .page(new BasicPage(R.drawable.ic_edit_white,
                        "Customizable",
                        "All elements of the welcome screen can be customized easily.")
                        .background(R.color.blue_background)
                )

                .swipeToDismiss(true)
                .exitAnimation(android.R.anim.fade_out)
                .build();
    }

    public static String welcomeKey() {
        return "WelcomeScreen";
    }
}

When you rotate the screen during the welcome screens (i.e. before you press "Done") , you'll end up with several identical welcome activities started.

That basically means that when you finish the welcome steps, you'll see a new welcome guide until you remove all the stacked welcome activities.
