retrieving the id of the view that was clicked

Question

I'm using MyActivity extends Activity implements OnClickListener{

This activity references around 10+ buttons and has setOnClicklistener(this) method called on every button.

@Override 
public void onClick(View v){
    //here I need to get the id of the view that was clicked...
    //Depending on the button that was clicked different actions need to be called...
    //How do I get the ID of the button that was clicked...
}

Why not google it first? http://developer.android.com/reference/android/view/View.html#getId() — Eugene Popovich, May 01 '13 at 10:21

@Override 
public void onClick(View v){
switch(v.getId()){
    case R.id.btnCancel:
        //your code for onclick of that button
        break;
}

  @Override 
    public void onClick(View v){
        int id = v.getId();
        if(id == R.id.button_ok){

         }

    }

The View parameter that is sent to your onClick method is the actual button that was clicked, therefore you can check which one it is, for example:

@Override 
public void onClick(View v){
    switch(v.getId()) {
        case R.id.button_1: ...; break;
        case R.id.button_2: ...; break;
        case R.id.button_3: ...; break;
        ...
        default: //unknown button clicked
    }
}

This is only one option, there are other. Search google for more info.

use :

if(v.getId()==R.id.whatever)
{
// do something
}

or you can even use : Button btn = (Button)findViewById(R.id.btn);

if(v==btn)
{
// do something
}

but the second one is not recommended.
