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>
