Android 在ViewFlipper中运行动画以在按钮多次单击时翻转图像

我正在安卓系统中开发LCR骰子游戏，我遇到了一个问题，当我尝试再次单击按钮运行图像翻转动画时，我正在使用

Asynctask

运行动画 这是我的项目的示例代码：

public class FlippingImage extends AsyncTask<Void, Long, Long>
    {

        @Override
        protected Long doInBackground(Void... params) {

            // TODO Auto-generated method stub
            int timer=0;

            mp=MediaPlayer.create(LCRDiceActivity.this,R.raw.rollingdices);
            mp.start();
            while (timer<5000) 
            {
                mp.start();

        Log.i("LCRgame", "start flip");

        mFlipper.startFlipping();
        mFlipper.setInAnimation(AnimationUtils.loadAnimation(LCRDiceActivity.this, R.anim.push_up_in));
        mFlipper.setOutAnimation(AnimationUtils.loadAnimation(LCRDiceActivity.this, R.anim.push_up_out));
        mFlipper2.startFlipping();
        mFlipper2.setInAnimation(AnimationUtils.loadAnimation(LCRDiceActivity.this, R.anim.push_up_in));
        mFlipper2.setOutAnimation(AnimationUtils.loadAnimation(LCRDiceActivity.this, R.anim.push_up_out));
        mFlipper3.startFlipping();
        mFlipper3.setInAnimation(AnimationUtils.loadAnimation(LCRDiceActivity.this, R.anim.push_up_in));
        mFlipper3.setOutAnimation(AnimationUtils.loadAnimation(LCRDiceActivity.this, R.anim.push_up_out));    
        SystemClock.sleep(1000);
        timer=timer+1000;

            }  

        return null;

        }

        @Override
        protected void onProgressUpdate(Long... values) {
            // TODO Auto-generated method stub

            super.onProgressUpdate(values);

            LCRDiceActivity.this.ChipsCountPlayer1.setText(ChipsCount1);
        }

        @Override
        protected void onPostExecute(Long result) {
            // TODO Auto-generated method stub
            //mFlipper.stopFlipping();
             Random myRondom=new Random();
                int myNumber=myRondom.nextInt(5)+1;
                switch (myNumber) {
                case 1:
                    mFlipper.setDisplayedChild(mFlipper.indexOfChild(findViewById(R.id.img_L_1)));

                     ChipsCount1=ChipsCount1-1;

                    break;
                case 2:
                    mFlipper.setDisplayedChild(mFlipper.indexOfChild(findViewById(R.id.img_C_1)));
                    ChipsCount1=ChipsCount1-1;

                    break;
                case 3:
                    mFlipper.setDisplayedChild(mFlipper.indexOfChild(findViewById(R.id.img_R_1)));

                    ChipsCount1=ChipsCount1-1;
                    break;
                case 4:
                    mFlipper.setDisplayedChild(mFlipper.indexOfChild(findViewById(R.id.img_dot_1)));

                    break;
                case 5:
                    mFlipper.setDisplayedChild(mFlipper.indexOfChild(findViewById(R.id.img_dot_1)));

                    break;
                case 6:
                    mFlipper.setDisplayedChild(mFlipper.indexOfChild(findViewById(R.id.img_dot_1)));

                    break;
                default:
                    break;

                }   

我得到了这个错误：

如何解决此问题请帮助我？

首先，错误是您不能触摸ViewFlipper，除非您处于创建ViewFlipper的同一线程中（这是我假设的UI线程）

看起来您可能必须使用runOnUiThread（Runnable）来处理视图翻转器上的动画

private OnClickListener StartClickListener=new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub

        // flipImage=new FlippingImage();

        // flipImage.execute( );

            Runnable myRunner = new Runnable(){
                 public void run() {
                    new FlippingImage().execute();
            }};
            myHandler=new Handler();
            myHandler.post(myRunner);


        }


    };
