如何识别单击了哪个“视图”？

Question

Look at following android code. IMGS is a 2 dimensional array of ImageView . I am adding onClickListener to it in a for loop. How to identify which view has been clicked ? I dont want to iterate over all the 36 elements using view.getId(); .

private static final Integer[] Icons = {
    R.drawable.r,
    R.drawable.re,
    R.drawable.u,
    R.drawable.et,  
    R.drawable.w,
    R.drawable.ya
};
private ImageView[][] IMGS= new ImageView[6][6];

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    IMGS[0][0] = (ImageView) findViewById(R.id.immg11);



    for (int i=0; i < 6; i++)
    {
    for (int j=0; j<6; j++)
    {

    Drawable d = getResources().getDrawable(Icons[i]);

    IMGS[i][j].setImageDrawable(d);

     IMGS[i][j].setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
//HOW TO KNOW WHICH VIEW HAS BEEN CLICKED ?
            }
    });
    }
    }



    }

Answer 1

Notice the View argument passed to onClick(View v) ? It's the view that was clicked.

You can call v.getId() to retrieve its id.

Agreed, but there are 36 elements over which i have to iterate if I use this method. Is there a way to know the indexes of clicked IMGS ?

You can use setTag() to save whatever data you want in each view and retrieve it later with getTag() .
