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"
    android: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="true"
          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"/>
      <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;
        }
 
    }
}
