Question

I am inflating an xml having button, multiple times and i am able to do so perfectly but the problem is when I click the button,i want to show which button is clicked.

Answer 1

items you are adding programmatically, you must have to assign ids to them.

b.setId(1);

EDITED:

public class DynamicLayoutActivity extends Activity implements OnClickListener{
private static final int MY_BUTTON = 9000;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    LinearLayout ll = (LinearLayout)findViewById(R.id.layout1);

    // add button
    Button b = new Button(this);
    b.setText("Button added dynamically!");
    b.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,   LayoutParams.WRAP_CONTENT));
    b.setId(MY_BUTTON);
    b.setOnClickListener(this);
    ll.addView(b);
}
 public void onClick(View v) {
        Toast toast;
        Log.w("ANDROID DYNAMIC VIEWS:", "View Id: " + v.getId());
        switch (v.getId()) {
        case MY_BUTTON:
            toast = Toast.makeText(this, "Clicked on my dynamically added button!", Toast.LENGTH_LONG);
            toast.setGravity(Gravity.TOP, 25, 400);
            toast.show();    
        }
    }

public class InflateExActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        LinearLayout lLayout;
        Button b = null;
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        for(int i=0;i<3;i++){
            final LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
             b = (Button) inflater.inflate(R.layout.buttons, null);
             b.setId(i);
            lLayout = (LinearLayout) findViewById(R.id.layout1);
            lLayout.addView(b);
            b.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                Toast.makeText(InflateExActivity.this, "Button Clicked :"+v.getId(),
                        Toast.LENGTH_LONG).show();
            }
        });
    }
