Hi, that's mentioned earlier in other issues, but i open a new one just to discuss it.

Material design specs doesn't cover the light with light problem:

It will be great if we can set a color for the BottomBar at anytime, and also will be cool to have a custom attribute to set it via theme.

If you want i can open a PR for it

how to hide softkey area?

Why the licenses are inside of the folders of the library? It would be better to use one file in the root of the library.

When I use 3 items or less I can't seem to be able to change each item color, it's being set to my primary color automatically which in my case doesn't fit.

The tablet side bar seems to always be white, even changing the new color normally doesn't work. Is this intentional?

After the latest update, the bottom bar is taking up part of the bottom layout (see how the FAB is overlapped), I guess because it isn't pushing it up?

Hello, I used the code below, the frame layout have recyclerview, but it doesn't show with BottomBar, only recyclerview or bottombar not both..

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <com.roughike.bottombar.BottomBar
        android:id="@+id/bb_bottom_bar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/white" />
    <FrameLayout
        android:id="@+id/fragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

Just updated to the latest build and it now adds space above the attached view. Check out the screenshot.

will you release a gradle?
and is this library have been finished for stable use? do you still have some import feature to add or modify?

Thank you for your great job~
Best Wishes~

After enabling dark mode with useDarkTheme(true), the bottom bar looks exactly the same as before. Selecting a tab causes it to disappear (I'm guessing because the text is now white):

How use it in activity_main.xml file rather than in MainActivity.java?

After calling SelectTabAtLocation I am unable to select card manually. However another SelectTabAtLocation change location normally.

I'm running Cyanogenmod 12 (Android 5.1.1) on my OnePlus One and I when I went for a trial run I noticed that the library always detects the software navbar as being active. It's possible to enable it and use it instead of the hardware buttons on the device, but by default it's not active.

It might be worth noting that I have configured my hardware menu button as recent apps but as far as I've noticed no changes when I configure it as menu button.

Hi,

First nice job doing this library, but there are few things I would change.

1. Make it more flexible, I do not see the reason why to create the bar dynamically in java. This is a ui library, thus should be provided as xml widget. Why? well, it makes it dynamic, flexible and visually to have it on the xml, the dev will be able to decide if wants to have some other view on top, for example coordinator layout? what happen here with the scroll behavior? etc...
2. I would keep it simple! I don't see the reason why the BottomBar should be handling fragments. It should only be responsible of creating the tabs and the proper animations for each item as well as notifying on event. That's the problem of some UI libraries, they try to do too much.
3. Related to the first point. Create and style_attribute so the dev can set a menu from xml.
4. Add ability to set the full color of the BottomBar by tab, so a tab should define, icon, text, color

If I have so time this weekend I maybe fork it and make some pull request.

Br,
Marcel

Anything known?

In Can it handle my Fragments and replace them automagically when a different tab is selected?, codes are:

mBottomBar.setFragmentItems(getSupportFragmentManager(), R.id.fragmentContainer,
    new BottomBarFragment(SampleFragment.newInstance("Content for recents."), R.drawable.ic_recents, "Recents"),
    new BottomBarFragment(SampleFragment.newInstance("Content for favorites."), R.drawable.ic_favorites, "Favorites"),
    new BottomBarFragment(SampleFragment.newInstance("Content for nearby stuff."), R.drawable.ic_nearby, "Nearby")
);

But in Separate BottomBars for individual Fragments, they are:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)     {
    View view = inflater.inflate(R.layout.my_fragment_layout, container, false);
    // initialize your views here

    BottomBar bottomBar = BottomBar.attach(view, savedInstanceState);
    bottomBar.setItems(
        new BottomBarTab(R.drawable.ic_recents, "Recents"),
        new BottomBarTab(R.drawable.ic_favorites, "Favorites"),
        new BottomBarTab(R.drawable.ic_nearby, "Nearby")
    );

    // Important! Don't return the view here. Instead, return the bottomBar, as it already contains your view.
    return bottomBar;
}

So if I wanna use Bottom bars connected with 4 different fragments, what should I use?

BTW, you guys are really fast for this repository.

missing drawable

Hi, guys.

Can this library used on the left of the Tablets?

the top border is ugly, how to style it, such as color, size, and so on?

Not sure if it's just me.. but I have 5 menu items.. I can't seem to get back to home (0).

I can click and go through all the others fine but clicking home doesn't work. except on the one activity which I have: mBottomBar.selectTabAtPosition(2, false); set in the onResume.. and that ONLY works if I go to menu item 2 then 3, hit return, and then click on 0.

If I click on item 2, then back to home it doesn't work.

I don't know if it was already reported, but when I implement this library and try to attach a snack bar like so:

Snackbar.make(bottomBar, "Some text", Snackbar.LENGTH_LONG).show();

I get this result (The snackbar overlays the bottom bar).

According to the guidelines it should look like this.

And once again, thank you for this great and quick implementation.

My Fragment with setRetainInstance = true restore OnCreate() -> OnDestroy() when chanhge orientation

Can we change bottom bar size ?

If no detect whether android device have soft navigation bar or not then the height of bottom bar will abnormal.
Modification:
BottomBar.java
navBarMagic() {
...
boolean hasMenuKey = ViewConfiguration.get(activity).hasPermanentMenuKey();
boolean hasBackKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_BACK);
final int navBarHeight;

        if(!hasMenuKey && !hasBackKey) {
          if (navBarIdentifier > 0) {
            navBarHeight = res.getDimensionPixelSize(navBarIdentifier);
          } else {
            navBarHeight = MiscUtils.dpToPixel(activity, 48);
          }
        } else {
          navBarHeight = 0;
        }

...
}

I'm using your BottomBar with another good lib to generate icons : Android Iconics. Its implementation is so easy, you can maybe refer a link into the readme for people who want ? Or don't knoa about that lib ?
https://github.com/mikepenz/Android-Iconics
quick showcase :

bottomBar = BottomBar.attach(view, savedInstanceState);
        bottomBar.setFragmentItems(getActivity().getSupportFragmentManager(), R.id.container,
                        new BottomBarFragment(new LatestKitFragment(), new IconicsDrawable(getActivity(), CommunityMaterial.Icon.cmd_trending_up).sizeDp(18), "Trending"),
                        new BottomBarFragment(new LatestKitFragment(), new IconicsDrawable(getActivity(), CommunityMaterial.Icon.cmd_newspaper).sizeDp(18), "Latest"),
                        new BottomBarFragment(new LatestKitFragment(), new IconicsDrawable(getActivity(), CommunityMaterial.Icon.cmd_tag_faces).sizeDp(18), "All")
        );

Is it possible to change the typeface of the labels by a function like bottomBar.setTypeface(Typeface tf) ?

Hello, just started checking this out and it seems really cool. However I can't seem to find out how to set the background color or item selected color? Thanks and continue the great work!

ver1.0.5

i did not set "mapColorForTab()" method.

(mColorMap is null)

thank you.

I'm using a SearchView, and I noticed that the bar sits above the keyboard and covers up some of the search results. I've attached a screenshot:

I'm using a drawer menu, so I use the bottom tabs into a fragment. But when I open the drawer, tabs are above the drawer.

A library shouldn't declare unnecessary attributes on the Application as doing so will automatically merge them into app's manifest. For example, an app that doesn't declare supportsRtl will now have it set to true after importing this library, even though the default value should be false.

BottomBar/bottom-bar/src/main/AndroidManifest.xml

<application
        android:allowBackup="true"
        android:label="@string/app_name"
        android:supportsRtl="true">

</application>

Hi. Thank you for your amazing lib!
I have a few questions, answer on which I didn't find at documentation.

1. how can I make title always visible for all tabs? As on your first example animation on the readme.
2. How can I create my activity with BottomBar wich will stay by default on the second position, for example?

Should probably be auto adjusted to "dark style" if the app is using night mode.

Awesome job with the library!

I was surprised to see that selectTabAtPosition(...) only updates the selected tab and not the current fragment. It should update both or there should be a separate method that does it.

using 1.0.1, my app runs well, except the ugly top border.
after switch to 1.0.3, and add the statement:mBottomBar.hideShadow(), just like below:
mBottomBar = BottomBar.attach(this, savedInstanceState); mBottomBar.hideShadow(); mBottomBar.setItemsFromMenu(R.menu.menu_bottombar, new OnMenuTabSelectedListener() { @Override public void onMenuItemSelected(int resId) { switch (resId) { case R.id.bottomBarHome: displayView(0); break;
the ugly top border appear above the toolbar:
before:

after:

next, when click the bottom icon, error occurs:

the code have been posted in the issue:
How to style top border? #3

I want to get this result.

Here is my current code:

       bottomBar = BottomBar.attach(this, savedInstanceState);

        bottomBar.setItemsFromMenu(R.menu.bar, new OnMenuTabSelectedListener() {
            @Override
            public void onMenuItemSelected(int resId) {

            }
        });
        bottomBar.mapColorForTab(0, ContextCompat.getColor(this, R.color.primary_dark));
        bottomBar.mapColorForTab(1, ContextCompat.getColor(this, R.color.md_teal_600));
        bottomBar.mapColorForTab(2, ContextCompat.getColor(this, R.color.md_red_500));
        bottomBar.mapColorForTab(3, ContextCompat.getColor(this, R.color.md_blue_grey_500));

But the result of this code is a black navbar.

What am I missing?

Hi, this was a fast release! I was just reading about this a couple of days ago.

I noticed that the second gif you posted does not follow the material design specs. The active & inactive items don't shrink or expand.

It would be awesome if this library also work with Fragments and Fragmentmanager. Some people like me don't use support fragments.

mBottomBar.noTopOffset() cannot find

The spec sheet recommend using this kind of animation.

Would be awesome if you could implement it.

Thanks for your work BTW, it's a great lib.

I using the latest version of library, but every time when I launch app on device with android 5+ I have a gap like on screen:
http://snag.gy/ugDqX.jpg
On device with Android 4.4 everything is fine:
http://snag.gy/yDSf3.jpg

The issue https://github.com/roughike/BottomBar/issues/24 still occurs with version 1.0.9~1.1.1, only 1.0.7 and 1.0.8 works well.
When using mBottomBar.noTopOffset() with version 1.1.1, the position of top toolbar isn't right, just as below.

There is a useful medium article how to hide the bottom bar when scrolling down. Maybe you can implement this feature to this library. https://medium.com/@nullthemall/bottom-navigation-behavior-388b9b206667#.7ufpfhq3a
