a simple slide layout library,just one java class file.
一个侧滑删除的库和demo，仅仅只是一个自定义控件搞定，提供了普通用法和listview，recyclerview用法实例。
关于滑动或touch功能，onTouchEvent方法可以搞定。但是本例没有这么复杂，借助ViewDragHelper工具类处理。
本例提供4种滑动效果：
- options隐藏菜单跟随content布局滑动
- options隐藏菜单固定在content底部，仅由content布局滑动
- 从左侧滑出
- 从右侧滑出
仅仅以上4种效果，代码逻辑就开始有点复杂，故没有考虑options和content布局从上下两侧滑动。

#部分代码:
##activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:slide="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.duke.slidelayout.SlideLayout
android:id="@+id/slideLayout"
android:layout_width="match_parent"
android:layout_height="60dp"
slide:canDrag="true"
slide:contentResId="@layout/item_content"
slide:optionsLayoutPosition="follow"
slide:optionsResId="@layout/item_options"
slide:slideDirection="right" />
...
</LinearLayout>
slide:contentResId="@layout/item_content" 内容布局，即上层布局
slide:optionsResId="@layout/item_options" 操作菜单布局，即下层布局

##MainActivity.java:
public class MainActivity extends AppCompatActivity implements View.OnClickListener,
SlideLayout.OnOptionsStateChangeListener, SlideLayout.OnChildClickListener {
private SlideLayout slideLayout;
private Button setSlideDirection1, setSlideDirection2, setOptionsLayoutPosition1,
setOptionsLayoutPosition2, setOpenedfalse, setOpenedtrue;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
slideLayout = (SlideLayout) findViewById(R.id.slideLayout);
slideLayout.setOnOptionsStateChangeListener(this);
slideLayout.setOnChildClickListener(this);
setSlideDirection1 = (Button) findViewById(R.id.setSlideDirection1);
setSlideDirection2 = (Button) findViewById(R.id.setSlideDirection2);
setOptionsLayoutPosition1 = (Button) findViewById(R.id.setOptionsLayoutPosition1);
setOptionsLayoutPosition2 = (Button) findViewById(R.id.setOptionsLayoutPosition2);
setOpenedfalse = (Button) findViewById(R.id.setOpenedfalse);
setOpenedtrue = (Button) findViewById(R.id.setOpenedtrue);
setSlideDirection1.setOnClickListener(this);
setSlideDirection2.setOnClickListener(this);
setOptionsLayoutPosition1.setOnClickListener(this);
setOptionsLayoutPosition2.setOnClickListener(this);
setOpenedfalse.setOnClickListener(this);
setOpenedtrue.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.setSlideDirection1:
slideLayout.setSlideDirection(SlideLayout.SlideDirection.LEFT);
break;
case R.id.setSlideDirection2:
slideLayout.setSlideDirection(SlideLayout.SlideDirection.RIGHT);
break;
case R.id.setOptionsLayoutPosition1:
slideLayout.setOptionsLayoutPosition(SlideLayout.OptionsLayoutPosition.FIXED);
break;
case R.id.setOptionsLayoutPosition2:
slideLayout.setOptionsLayoutPosition(SlideLayout.OptionsLayoutPosition.FOLLOW);
break;
case R.id.setOpenedfalse:
slideLayout.setOpened(false);
break;
case R.id.setOpenedtrue:
slideLayout.setOpened(true);
break;
}
}
@Override
public void onOptionsViewChange(boolean isOpened) {
Toast.makeText(this, isOpened ? "菜单打开" : "菜单关闭", Toast.LENGTH_SHORT).show();
}
@Override
public void onChildClick(View view) {
String string = "";
if (view.getId() == R.id.content_root) {
string = "内容点击";
} else if (view.getId() == R.id.content_text) {
TextView textView = (TextView) view;
string = textView.getText().toString();
} else if (view.getId() == R.id.options_root) {
string = "操作菜单点击";
} else if (view.getId() == R.id.tv_open) {
TextView textView = (TextView) view;
string = textView.getText().toString();
} else if (view.getId() == R.id.tv_delete) {
TextView textView = (TextView) view;
string = textView.getText().toString();
}
Toast.makeText(MainActivity.this, string, Toast.LENGTH_SHORT).show();
}
}
无论是content布局控件还是options布局控件的点击事件，我不清楚各自的id。
我统一都用SlideLayout.OnChildClickListener接口提供给您，具体是哪个点击了，请在回调中判断id，再做处理。
参考public void onChildClick(View view) 方法；

至于在listview和recyclerview中的用法，请参考github库中的demo：
./demo/SlideLayout_listview
./demo/SlideLayout_recyclerview
