LayoutAnimationController动画效果，一次出现

1. 动画list_item_layout.xml

1. 每个列表项动画list_item_alpha.xml

1. 主界面布局文件activity_main.xml
   特别注意要在ListView中添加android:layoutAnimation="@anim/list_item_layout"

1. 列表布局文件item_list.xml

1. 主界面代码

public class MainActivity extends AppCompatActivity {  private ListView mListView;  private static final String[] STRINGS = {      "BruceZhang", "Alpha", "Translate", "Blanklin", "Rotate", "GreenFrank"  };  private ArrayAdapter
     
       mAdapter;  @Override protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    mListView = (ListView) this.findViewById(R.id.listView);    mAdapter = new ArrayAdapter<>(this, R.layout.item_list, STRINGS);  }  public void test(View view) {    mListView.setAdapter(mAdapter);  }  public void clear(View view) {    mListView.setAdapter(null);  }}
     

二、代码配置

1. 动画文件

1. 主界面布局文件

1. 主界面动画设置

public class MainActivity extends AppCompatActivity {  private ListView mListView;  private static final String[] STRINGS = {      "BruceZhang", "Alpha", "Translate", "Blanklin", "Rotate", "GreenFrank"  };  private ArrayAdapter
     
       mAdapter;  @Override protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    mListView = (ListView) this.findViewById(R.id.listView);    mAdapter = new ArrayAdapter<>(this, R.layout.item_list, STRINGS);    // 1. 创建一个Animation对象    Animation animation = AnimationUtils.loadAnimation(this, R.anim.list_item_alpha);    // 2. 使用如下代码创建LayoutAnimationController对象    LayoutAnimationController lac = new LayoutAnimationController(animation);    // 3. 设置控件显示的顺序    lac.setOrder(LayoutAnimationController.ORDER_RANDOM);    // 4. 为ListView设置LayoutAnimationController尚需经    mListView.setLayoutAnimation(lac);  }  public void test(View view) {    mListView.setAdapter(mAdapter);  }  public void clear(View view) {    mListView.setAdapter(null);  }}
