一起学android之设置ListView数据显示的动画效果（24）

效果图：



平时我们要实现ListView数据显示时的动画效果，可以使用LayoutAnimationController为ListView设置动画效果，并通过ListView的setLayoutAnimation方法来设置，最后startLayoutAnimation，启动动画。参看以下代码:

public class MainActivity extends Activity {
private ListView lv_arrayadapter;
private String[] str_name = new String[] { "jack", "debb", "robin", "kikt",
"dog", "cat", "elep" };
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
setData();
loadAnimation();
}

private void loadAnimation() {
/*
* 创建动画的集合
*/
AnimationSet set = new AnimationSet(false);

Animation animation ;
/*
* 创建旋转动画
*/
animation = new RotateAnimation(180, 10);
animation.setDuration(1000);
set.addAnimation(animation);

LayoutAnimationController controller = new LayoutAnimationController(
set, 1);
controller
.setInterpolator(this, android.R.anim.accelerate_interpolator);
controller.setAnimation(set);
lv_arrayadapter.setLayoutAnimation(controller);
lv_arrayadapter.startLayoutAnimation();
}

private void initView() {
lv_arrayadapter = (ListView) findViewById(R.id.lv_arrayadapter);
// 注册监听事件
lv_arrayadapter.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(MainActivity.this, str_name[position],
Toast.LENGTH_SHORT).show();

}
});

}

private void setData() {
// 创建ArrayAdapter
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
MainActivity.this, android.R.layout.simple_list_item_1,
str_name);
// 绑定适配器
lv_arrayadapter.setAdapter(arrayAdapter);
}

}

activity_main.xml:

<RelativeLayout 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"
>

<ListView
android:id="@+id/lv_arrayadapter"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ListView>

</RelativeLayout>
