When inflating a layout xml dynamically multiple times, how can I differentiate or identify the Button widgets?

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

You can use setTag() to each button. Inside the for loop you can assign button.setTag(). And you can use getTag() to retrieve button's tag. After you inflate the layout, add a tag to your button

EDIT2: You should inflate the layout and then look up for your button id. See below:

    public class InflateExActivity extends Activity {
            /** Called when the activity is first created. */
            @Override
            public void onCreate(Bundle savedInstanceState) {
                LinearLayout lLayout;
                final 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);
View v = inflater.inflate(R.layout.buttons, null);
b = v.findViewById(R.id.your_button_id);
    //                 b = (Button) inflater.inflate(R.layout.buttons, null);
                       b.setTag(i); // you'll get 0,1,2 as tags
                    lLayout = (LinearLayout) findViewById(R.id.layout1);
                    lLayout.addView(b);
                    b.setOnClickListener(new OnClickListener() {

                        public void onClick(View v) {
    int specificButton = (Integer)v.getTag();//Changed here.......
                            Toast.makeText(InflateExActivity.this, "Button Clicked"+Integer.toString(specificButton),
                                    Toast.LENGTH_LONG).show();
                        }
                    });
                }
            }  
        }
