The view that is passed in is the one that was clicked, therefore it has the id.

view.getId() == R.id.button3

If you still need help, share more of your code.

Well you will require some onclick listeners for the button, you can then set an id or name in the onclick e.g

 final Button button1 = (Button) findViewById(R.id.button_id);
     button1.setOnClickListener(new View.OnClickListener() {
         public void onClick(View v) {
             text.settext("Button1 Clicked")
         }
     });

you can define one click listener and set this listener for all buttons. For example:

private OnClickListener genericListerner = new OnClickListener() { 
    public void Click(View v) {
        switch(v.getId())
        {
              case R.id.button3:
               text.setText(button3.getText().toString());
              break;
              case R.id.button4:
              text.setText(button4.getText().toString());
              break;
              case R.id.button5:
              text.setText(button5.getText().toString());
              break;
              default:
              //do something
    } 
};

and you set the listeners like the following:

button3.setOnClickListener(genericListener);
button4.setOnClickListener(genericListener);
button5.setOnClickListener(genericListener);

I am not sure whether this is what you are asking, but what this code basically does is that, if you click button 3 it sets the textview's text to button 3's text, if you click button 4 it sets the textview's text to button 4's text and if you click button 5, it sets the textview's text to button 5's text.

Hope this helps.

That realy help, thanks. And thanks to all the people who try help me. — , Jul 21 '14 at 21:34
