Retrieving The Id Of The View That Was Clicked

I'm using MyActivity extends Activity implements OnClickListener{ This activity references around 10+ buttons and has setOnClicklistener(this) method called on every button. @Overr

Solution 1:

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

Solution 2:

you can use following method to get id.

v.getId()

Solution 3:

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

         }

    }

Solution 4:

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.

Solution 5:

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.
