暂停动画无法正常工作

Question

我正在开发一款游戏。它一切运作良好，我唯一需要的是当我按下手机上的主页或开/关按钮时我的动画暂停。就我记录正确而言，暂停脚本（找到here）效果很好。它不断增加时间并将其应用于动画。然而，当我恢复游戏时，动画都会在屏幕左侧恢复，而不是在我暂停时原来的位置。这是我的剥离代码。我真的希望有人可以帮助我。

public class GameView extends Activity{
    ImageView peanut;
    TranslateAnim movePeanut;
    AnimationSet animSet = new AnimationSet(true);



    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.gameviewlayout);
        Display display = getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        int width = size.x;

        movePeanut = new TranslateAnim(width,0,0,0);
        movePeanut.setDuration(5000);
        movePeanut.setRepeatCount(-1);
        movePeanut.setRepeatMode(Animation.REVERSE);

        animSet.addAnimation(movePeanut);
        animSet.setFillAfter(true);
        peanut = (ImageView) findViewById(R.id.imgview1);
        peanut.startAnimation(animSet);


    @Override
    protected void onStart() {
        // TODO Auto-generated method stub
        super.onStart();


    }

    @Override
    protected void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
        movePeanut.resume();



    }

    @Override
    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();
        movePeanut.pause();
    }

    @Override
    protected void onStop() {
        // TODO Auto-generated method stub
        super.onStop();

    }
    public void finish (){
        Intent intent = new Intent (GameView.this, MainActivity.class);
        startActivity(intent);
    }

    public class TranslateAnim extends TranslateAnimation{

        public TranslateAnim(float fromXDelta, float toXDelta, float fromYDelta,
                float toYDelta) {
            super(fromXDelta, toXDelta, fromYDelta, toYDelta);
            // TODO Auto-generated constructor stub
        }

        private long mElapsedAtPause=0;
        private boolean mPaused=false;

        @Override
        public boolean getTransformation(long currentTime, Transformation outTransformation) {
            if(mPaused && mElapsedAtPause==0) {
                mElapsedAtPause=currentTime-getStartTime();
            }
            if(mPaused)
                setStartTime(currentTime-mElapsedAtPause);

            boolean returnValue = super.getTransformation(currentTime, outTransformation);


            return returnValue;
        }

        public void pause() {
            mElapsedAtPause=0;
            mPaused=true;
        }

        public void resume() {
            mPaused=false;
        }
    }
}
