使用线程/可运行在Android中运行重复动画

Question

My goal is to have a thread running that plays a sound then chooses a random animation and a random image and displays them.

It is currently working, but I was wondering if there is a better way. I have a Hacker's understanding of threading (as in, I only know that this works), so I'd appreciate some feedback. Also, I've been having issues with memory overflow in my app, is there a better way to manage this Activity memory-wise? Thank you so much!

public int[] images = {R.drawable.splat0,R.drawable.splat1,R.drawable.splat2,R.drawable.splat3,
        R.drawable.splat4,R.drawable.splat5,R.drawable.splat6,R.drawable.splat7,R.drawable.splat8,
        R.drawable.splat9};
public int[] anims= {R.anim.splat0,R.anim.splat1,R.anim.splat2,
        R.anim.splat3,R.anim.splat4,R.anim.splat5,R.anim.splat6};

MediaManager mp;
Handler tick_Handler = new Handler();
MyThread tick_thread = new MyThread();

@Override
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

    MainActivity.this.setContentView(R.layout.activity_main);
    mp = new MediaManager();

    image = (ImageView)this.findViewById(R.id.mainActivitySplat);

    tick_Handler.post(tick_thread);
}

@Override 
public void onStop(){
    tick_Handler.removeCallbacks(tick_thread);
    super.onStop();
}

@Override
public void onResume(){
    tick_Handler.post(tick_thread);
    super.onResume();
}

private class MyThread implements Runnable {
    @Override
    public void run() {     
        mp.playSoundClip(MainActivity.this,R.raw.swoosh);
        image.setBackgroundResource(images[(int)(Math.random()*splats.length)]);    
        Animation myAnim=AnimationUtils.loadAnimation(MainActivity.this,splatAnim[(int)(Math.random()*splatAnim.length)]);
        splat.startAnimation(myAnim);
        tick_Handler.postDelayed(tick_thread, 3500);
    }
} 

Edit: I have discovered this is a BAD way of using the Thread. MyThread holds an implicit reference to the Activity, and causes a massive memory leak. By changing the class to private static MyThread I solve the leak, but I have not yet figured out how to get the desired behavior this way. Will update later.

使用类似boolean isActibityKilled=true //when in onstop的标志boolean isActibityKilled=true //when in onstop中在可运行boolean isActibityKilled=true //when in onstop使用它来检查活动是否正在运行，如果活动未在运行，或者它已停止，则杀死线程
