Adapter the problem of executing only one animation in multiple frames

AnimationDrawable frameAnim=(AnimationDrawable)mContext.getResources().getDrawable(R.drawable.yellow_red_rent);
finalHolder1.cardBg.setBackgroundDrawable(frameAnim);
frameAnim.start();
AnimationDrawable frameAnim2=(AnimationDrawable)mContext.getResources().getDrawable(R.drawable.yellow_red_dian);
finalHolder1.r_light.setBackgroundDrawable(frameAnim2);
frameAnim2.start();

The above code is written in the card list adapter , Only found frameAnim2 Yes ,frameAnim Don't execute , Anyway, I didn't see its animation effect , Later, I tried to write in the child thread ：

new Thread(new Runnable() {
    @Override
    public void run() {
        AnimationDrawable frameAnim=(AnimationDrawable)mContext.getResources().getDrawable(R.drawable.yellow_red_rent);
        finalHolder1.cardBg.setBackgroundDrawable(frameAnim);// If you do not animate this frame xml resources , Because dragging real-time uses image resources , Drag a card and then click the corresponding like / Annoying button , Type conversion error will be reported ！
        frameAnim.start();
        AnimationDrawable frameAnim2=(AnimationDrawable)mContext.getResources().getDrawable(R.drawable.yellow_red_dian);
        finalHolder1.r_light.setBackgroundDrawable(frameAnim2);// If you do not animate this frame xml resources , Because dragging real-time uses image resources , Drag a card and then click the corresponding like / Annoying button , Type conversion error will be reported ！
        frameAnim2.start();
    }
}).start();

As a result, both frames of animation are executed , Without rhyme or reason ......
