本文实例为大家分享了android Studio实现简单补间动画的具体代码，供大家参考，具体内容如下

1、动画发在res/anim/，创建new/Directory

2、创建动画，  平移，缩放，旋转，改变透明度

//平移
<?XML version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

<translate

  android:fromXDelta="0.0"
  android:fromYDelta="0.0"
  android:toXDelta="100"
  android:toYDelta="0.0"
  android:repeatMode="reverse"
  android:repeatCount="infinite"
  android:duration="4000"
  />

</set>

//缩放
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale

  android:repeatMode="reverse"
  android:repeatCount="infinite"
  android:duration="3000"
  android:fromXScale="1.0"
  android:fromYScale="1.0"
  android:toXScale="0.5"
  android:toYScale="0.5"
  android:pivotX="50%"
  android:pivotY="50%"/>

</set>

//旋转
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

  <rotate android:fromDegrees="0"
    android:toDegrees="360"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatMode="reverse"
    android:repeatCount="infinite"
    android:duration="1000"
    />

</set>

//改变透明度
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha
  android:interpolator="@android:anim/linear_interpolator"
  android:repeatMode="reverse"
  android:repeatCount="infinite"
  android:duration="1000"
  android:fromAlpha="1.0"
  android:toAlpha="0.0"/>

</set>

 3，布局activity_main.xml，点击按钮图片发送变化,图片需要自己下载添加44

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  a编程客栈ndroid:layout_height="match_parent"
  android:layout_weight="1"
  android:orientation="vertical"
  tools:context=".MainActivity">

   <ImageView
     android:layout_width="300dp"
     android:layout_height="300dp"
     android:layout_centerInParent="truejavascript"
     android:layout_gravity="center"
     android:id="@+id/fk"
     android:src="@drawable/ff"/>

 <LinearLayout
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="horizontal">

   <Button
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="平移"
   android:textSize="24sp"
   android:layout_weight="1"
    android:gravity="center"
     android:layout_gravity="bottom"
   android:id="@+id/but"/>
   <Button
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="缩放"
     android:textSize="24sp"
     android:layout_gravity="bottom"
     android:layout_weight="1"
     android:gravity="center"
     android:id="@+id/but1"/>
   <Button
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="旋转"
     android:textSize="24sp"
     android:gravity="center"
     android:layout_gravity="bottom"
     android:layout_weight="1"
     android:id="@+id/but2"/&gt;
   <Button
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="改变透明度"
     android:textSize="24sp"
     android:gravity="center"
     android:layout_gravity="bottom"
     android:layout_weight="1"
     android:id="@+id/but3"/>
 </LinearLayout>

</RelativeLayout>

4、逻辑代码MainActivity

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
  private ImageView imageView;
  private Button button;
  private Button button1;
  private Button button2;
  private Button button3;

  @RequiresApi(api = Build.VERSION_CODES.N)
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //要用控件，定id
    button=findViewById(R.id.but);
    button1=findViewById(R.id.but1);
    button2=findViewById(R.id.but2);
    button3=findViewById(R.id.but3);

    imageView=findViewById(R.id.fk);
    button.setOnClickListener(this);
    button1.setOnClickListener(this);
    button2.setOnClickListener(this);
    button3.setOnClickListener(this);

  }

  @Override
  public void onClick(View view) {
    switch (view.getId()){
      case R.id.but:
        Animation translation= AnimationUtils.loadAnimation(this,R.anim.translate);
        imageView.startAnimation(translation);
        break;
      case R.id.but1:
        Animation scale= AnimationUtils.loadAnimation(this,R.anim.scale);
        imageView.startAnimation(scale);
        break;
      case R.id.but2:
        Animation rotate= AnimationUtils.loadAnimation(this,R.anim.rotate);
        imageView.startAnimation(rotate);
        break;
      case R.id.but3:
        Animation alpha= AnimationUtils.loadAnimation(this,R.anim.alpha);
        imageView.startAnimation(alpha);
        break;
    }

  }
}
