Android中StackView的使用

StackView控件是AdapterViewAnimator的子列，以堆叠的方式显示多个列表项

• 在布局文件中加入加入一个StackView控件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="top.hellowoodes.stackview.MainActivity">


    <StackView  android:layout_width="match_parent" android:layout_height="wrap_content" android:loopViews="true" android:id="@+id/stackView" />
    <LinearLayout  android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom">

        <Button  android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="上一个" android:id="@+id/button" android:onClick="prev" android:layout_gravity="center_vertical" />

        <Button  android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="下一个" android:onClick="next" android:id="@+id/button2" android:layout_gravity="bottom" />
    </LinearLayout>


</LinearLayout>

• 在代码中为StackView适配Adapter

public class MainActivity extends AppCompatActivity {
    StackView stackView;

    int[] imageIds = new int[]{
            R.drawable.a,R.drawable.b,R.drawable.c,R.drawable.d,R.drawable.e,R.drawable.f
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         stackView = (StackView) findViewById(R.id.stackView);
        List<Map<String, Object>> listItems = new ArrayList<>();
        for (int i = 0; i < imageIds.length; i++) {
            Map<String, Object> listItem = new HashMap<String, Object>();
            listItem.put("iamge", imageIds[i]);
            listItems.add(listItem);
        }

        SimpleAdapter simpleAdapter = new SimpleAdapter(this,
                listItems,
                R.layout.cell,
                new String[]{"iamge"},
                new int[]{R.id.image1});
        stackView.setAdapter(simpleAdapter);
    }

    public void prev(View view) {
        stackView.showPrevious();
    }

    public void next(View view) {
        stackView.showNext();
    }
}

• R.layout.cell布局文件：

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

    <ImageView  android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/image1" android:layout_gravity="center" />
</LinearLayout>
