泄漏全班Android

Question

嗨，在我的应用程序中，我有一个被泄露的surfaceview类。当我使用MAT分析内存时，它会显示此类的多个实例。我想知道是否有人对如何修复它有任何见解。 下面是我认为可能导致它的一些片段。

    public void surfaceDestroyed(SurfaceHolder holder) {
    boolean retry = true;
    thread.setPause(true);
    Log.d("STATE","PAUSE2");
    userPaused = true;
    //sound.stopSound(1);
    while (retry) {
        try {
            Log.d("mState","surfaceDestroy");
            thread.join();
            retry = false;
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
    thread = null;
}



    public void surfaceCreated(SurfaceHolder holder) {
    if(thread.getState()== Thread.State.TERMINATED){             
         Log.d("mState","SurfaceCreatedNew");
         thread = new singleThread(holder, context,true,2,true, mHandler);
         thread.setPause(false);
         thread.start();
    }else {
         Log.d("mState","SurfaceCreatedOld");
         thread.setPause(false);
         thread.start();
    }
}


@Override
public void run() {
         while (!pause) {

             Canvas c = null;
                 try {
                     c = sHolder.lockCanvas(null);
                     synchronized (sHolder) {
                         if(!statePaused && !userPaused){
                             //Log.d("MOVE","MOVE");
                             powerUps();
                             moveAll();
                         }

                         doDraw(c);                      
                     }
                 } finally {
                     if (c != null) {    
                         sHolder.unlockCanvasAndPost(c);
                     }
                 }

         }  
         Log.e("mState","EndofRun");              
}
