Android UI Libs之AndroidSwipeLayout
1. 说明
AndroidSwipeLayout，顾名思义，Android平台上的滑动布局，是一个可以让我们很方便使用滑动的库，典型的应用就是侧滑删除与侧滑菜单。
2. 配置
在模块中添加依赖：compile "com.daimajia.swipelayout:library:1.2.0@aar"
3.基本使用
1. Show Mode
-
LayDown
- PullOut
2. Drag edge
- LEFT
- RIGHT
- TOP
- BOTTOM
3. 在xml布局文件中使用SwipeLayout
-
SwipeLayout的最后一个孩子是SurfaceView，其他孩子都是BottomView -
BottomView最好添加上andorid:layout_gravity属性
<com.daimajia.swipe.SwipeLayout
android:layout_width="match_parent"
android:layout_height="80dp">
<!-- Bottom View Start-->
<LinearLayout
android:background="#66ddff00"
android:id="@+id/bottom_wrapper"
android:layout_width="160dp"
android:layout_height="match_parent"
android:orientation="vertical">
<!--What you want to show-->
<TextView
android:text="欢迎关注我的微信公众号：Android技术漫谈"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<!-- Bottom View End-->
<!-- Surface View Start -->
<LinearLayout
android:padding="10dp"
android:background="#ffffff"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--What you want to show in SurfaceView-->
<TextView
android:text="欢迎关注我的github:lavor-zl"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<!-- Surface View End -->
</com.daimajia.swipe.SwipeLayout>
4. 在java文件中对SwipeLayout进行一些相关操作
SwipeLayout swipeLayout = (SwipeLayout)findViewById(R.id.sample1);
//set show mode.
swipeLayout.setShowMode(SwipeLayout.ShowMode.LayDown);
//add drag edge.(If the BottomView has 'layout_gravity' attribute, this line is unnecessary)
swipeLayout.addDrag(SwipeLayout.DragEdge.Left, findViewById(R.id.bottom_wrapper));
swipeLayout.addSwipeListener(new SwipeLayout.SwipeListener() {
@Override
public void onClose(SwipeLayout layout) {
//when the SurfaceView totally cover the BottomView.
}
@Override
public void onUpdate(SwipeLayout layout, int leftOffset, int topOffset) {
//you are swiping.
}
@Override
public void onStartOpen(SwipeLayout layout) {
}
@Override
public void onOpen(SwipeLayout layout) {
//when the BottomView totally show.
}
@Override
public void onStartClose(SwipeLayout layout) {
}
@Override
public void onHandRelease(SwipeLayout layout, float xvel, float yvel) {
//when user's hand released.
}
});
4. 高级使用
我们经常需要在ListView，RecyclerView等中使用侧滑删除或者侧滑菜单，那么我们如何利用AndroidSwipeLayout来实现呢。
Adapter的定义如下：
public class MyRecyclerViewAdapter extends RecyclerSwipeAdapter<MyRecyclerViewAdapter.MyViewHolder>{
private Context context;
private List<String> list;
public MyRecyclerViewAdapter(Context context, List<String> list) {
this.context = context;
this.list = list;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.adapter, parent, false);
return new MyViewHolder(view);
}
@Override
public void onBindViewHolder(MyViewHolder viewHolder, final int position) {
viewHolder.swipeLayout.setShowMode(SwipeLayout.ShowMode.LayDown);
viewHolder.surface.setText(list.get(position));
viewHolder.bottom.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
list.remove(position);
notifyDataSetChanged();
}
});
}
@Override
public int getItemCount() {
return list.size();
}
@Override
public int getSwipeLayoutResourceId(int position) {
return position;
}
public static class MyViewHolder extends RecyclerView.ViewHolder{
private SwipeLayout swipeLayout;
private Button bottom;
private TextView surface;
public MyViewHolder(View itemView) {
super(itemView);
swipeLayout=(SwipeLayout)itemView.findViewById(R.id.swipe_layout);
bottom=(Button)itemView.findViewById(R.id.bottom);
surface=(TextView)itemView.findViewById(R.id.surface);
}
}
}
adapter.xml的内容：
<com.daimajia.swipe.SwipeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/swipe_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- Bottom View Start-->
<LinearLayout
android:background="#66ddff00"
android:id="@+id/bottom_wrapper"
android:layout_width="160dp"
android:layout_height="match_parent"
android:orientation="vertical">
<!--What you want to show-->
<Button
android:id="@+id/bottom"
android:text="删除"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<!-- Bottom View End-->
<!-- Surface View Start -->
<LinearLayout
android:padding="10dp"
android:background="#ffffff"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--What you want to show in SurfaceView-->
<Button
android:id="@+id/surface"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<!-- Surface View End -->
</com.daimajia.swipe.SwipeLayout>
RecyclerView相关设置
List<String> list=new ArrayList<>();
for(int i=0;i<40;i++){
list.add("欢迎关注我的github:lavor-zl:"+(i+1));
}
MyRecyclerViewAdapter myRecyclerViewAdapter=new MyRecyclerViewAdapter(this,list);
recyclerview.setLayoutManager(new LinearLayoutManager(this));
recyclerview.setAdapter(myRecyclerViewAdapter);
这些代码基本上实现了侧滑删除，程序运行界面如下
继承RecyclerSwipeAdapter的Adapter比继承RecyclerView.Adapter的Adapter多了很多方法，常用的有下面几个：
-
openItem(int position)：打开某个item的侧滑 -
closeItem(int position)：关闭某个打开的侧滑 -
getOpenItems()：获取所有打开的item -
isOpen(int position):判断某个位置的item是否打开侧滑 -
getMode()：获取侧滑显示模式 -
setMode(Attributes.Mode mode)：设置侧滑显示模式
同理可以操作ListView等，操作ListView时可以让Adapter继承BaseSwipeAdapter
