我正在寻找让onCreate（）中的2个SceneAnimation（）一个接一个地播放的解决方案，它们同时播放，一个比另一个长，所以第二个播放然后播放首先踢第二个结束的帧所在的地方，我听说过AnimationListener，但我不知道如何将它合并到要听的类中，我将非常感谢一个演练或代码示例和解释我很新这个，谢谢你的时间

Answer 1

实际上这很简单。创建一个Animation实例并将AnimationListener附加到它。在onAnimationEnd中，您将开始第二个动画。 Et voila，两个按顺序执行的动画。

    Animation firstAnimation = new TranslateAnimation(getApplicationContext(), null);
    firstAnimation.setAnimationListener(new Animation.AnimationListener() {

        @Override
        public void onAnimationStart(Animation animation) { 
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
        }

        @Override
        public void onAnimationEnd(Animation animation) {
            Animation secondAnimation = new TranslateAnimation(getApplicationContext(), null);
            secondAnimation.start();
        }
    });

    firstAnimation.start();

import android.widget.ImageView;

class SceneAnimation {
public int x;
public ImageView mImageView;
public int[] mFrameRess;
public int[] mDurations;
public int mDuration;

public int mLastFrameNo;
public long mBreakDelay;

private AnimationListener mAnimationListener;

public SceneAnimation( ImageView pImageView, int[] pFrameRess, int[] pDurations ) {

mImageView = pImageView;
mFrameRess = pFrameRess;
mDurations = pDurations;
mLastFrameNo = pFrameRess.length - 1;

play( 1 );
}

public SceneAnimation( ImageView pImageView, int[] pFrameRess, int pDuration ) {
mImageView = pImageView;
mFrameRess = pFrameRess;
mDuration = pDuration;
mLastFrameNo = pFrameRess.length - 1;

mImageView.setImageResource( mFrameRess[0] );

playConstant( 1 );
}

public SceneAnimation( ImageView pImageView, int[] pFrameRess, int pDuration, long     pBreakDelay ) {
mImageView = pImageView;
mFrameRess = pFrameRess;
mDuration = pDuration;
mLastFrameNo = pFrameRess.length - 1;
mBreakDelay = pBreakDelay;

mImageView.setImageResource( mFrameRess[0] );
playConstant( 1 );
}

public void setAnimationListener(AnimationListener listener){
this.mAnimationListener = listener;
}

public void play( final int pFrameNo ) {

mImageView.postDelayed( new Runnable() {
    public void run() {

        mImageView.setImageResource( mFrameRess[pFrameNo] );
        if ( pFrameNo == mLastFrameNo ) {
            return;
        } else
            play( pFrameNo + 1 );

        // Callback when animation ends.
        if( mAnimationListener != null ){
            mAnimationListener.onAnimationEnd();
        }
    }
}, mDurations[pFrameNo] );
}

public void playConstant( final int pFrameNo ) {
mImageView.postDelayed( new Runnable() {
    public void run() {
        mImageView.setImageResource( mFrameRess[pFrameNo] );

        if ( pFrameNo == mLastFrameNo )
            playConstant( 0 );
        else
            playConstant( pFrameNo + 1 );

        // Callback when animation ends.
        if( mAnimationListener != null ){
            mAnimationListener.onAnimationEnd();
        }
    }
}, pFrameNo == mLastFrameNo && mBreakDelay > 0 ? mBreakDelay : mDuration );
}


public static interface AnimationListener {
public void onAnimationEnd();
// You can add onAnimationStart(), and do the same thing like onAnimationEnd.
}
};
