我应该将哪个监听器用于wordsearch android应用程序中的字母？

Question

....
case 5:
    sizeperbutton = sizeOfLayout/5;
    for( i = 0; i<25; i++) {
       buttons[i] = new Button(this)
       ll.addView(buttons[i]);
       ViewGroup.LayoutParams mParams = buttons[i].getLayoutParams();
       mParams.height = sizeperbutton;
       mParams.width = sizeperbutton;
       int j = (int)(Math.random()*26);
       buttons[i].setText(letterEN[j]);
       buttons[i].setTag(i);
       buttons[i].setOnTouchListener(new View.OnTouchListener() {

           @Override
           public boolean onTouch(View view, MotionEvent motionEvent) {
               Object tag = view.getTag();
               if(motionEvent.getAction() == MotionEvent.ACTION_DOWN){
                 /* Set the background drawable only for the button  I've clicked, and get its text and append it to a textView*/
               }
               if(motionEvent.getAction() == MotionEvent.ACTION_MOVE){
                 /* Set the background drawable all the buttons I dragged through my finger and append their letters to the same textView*/
               }
               if(motionEvent.getAction() == MotionEvent.ACTION_UP){
                 /*Release touching, check if the text which is stacked to the textView is contained by a list.*/
               }
               return false;
           }
       });
  }

在我的游戏活动中，它会在水平和垂直方向创建一个有5个按钮的区域。 所有这些都得到一个随机的字母，并获得触摸监听器，我认为不足以同时点击更多的对象，它只适用于一个按钮。我很欣赏任何来源或代码。我做了很长时间的研究，但最后我不得不要求提供信息。这就是我想要达到的目标：https://www.youtube.com/watch?v=NRIvZioTdMc。
