Question

我需要在imageview中振动图像

为此我用过

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <rotate
        android:duration="70"
        android:fromDegrees="-5"
        android:pivotX="50%"
        android:pivotY="50%"
        android:repeatCount="5"
        android:repeatMode="reverse"
        android:interpolator="@android:anim/linear_interpolator"
        android:toDegrees="5" />
    <translate
        android:fromXDelta="-10"
        android:toXDelta="10"
        android:repeatCount="5"
        android:repeatMode="reverse"
        android:interpolator="@android:anim/linear_interpolator"
        android:duration="70" />
</set>

实施类似

   Animation shake = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.testanimation);
                        findViewById(R.id.imgview).startAnimation(shake);

正常工作..但我想在imageview触摸时抖动图像并在用户触摸imageview时停止抖动

imgview.setOnTouchListener(new OnTouchListener() {
 @Override
 public boolean onTouch(View v, MotionEvent event) {
  System.out.println(event.getAction());
  switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN: 
         //WANT VIBRATEING/SHAKEING IMAGE
         break;
        case MotionEvent.ACTION_UP:
         //WANT TO STOP VIBRATEING/SHAKING IMAGE
         break;
   }
   break;
  }

如何使它成为可能？谢谢， Pragna
