How to know what is the button id that was clicked - android

I have created 3 buttons in my application which when clicked, will go to the method giveClue.

<ImageButton
        android:id="@+id/imageButton1"
        android:layout_width="24dp"
        android:layout_height="22dp"
        android:layout_alignTop="@+id/lifeButtonsLbl"
        android:layout_toLeftOf="@+id/ImageButton2"
        android:src="@drawable/icon"
        android:onClick="giveClue" />

    <ImageButton
        android:id="@+id/ImageButton2"
        android:layout_width="24dp"
        android:layout_height="22dp"
        android:layout_alignTop="@+id/imageButton1"
        android:layout_toLeftOf="@+id/ImageButton3"
        android:src="@drawable/icon" 
        android:onClick="giveClue"/>

    <ImageButton
        android:id="@+id/ImageButton3"
        android:layout_width="24dp"
        android:layout_height="22dp"
        android:layout_alignRight="@+id/frameLayout1"
        android:layout_alignTop="@+id/ImageButton2"
        android:src="@drawable/icon"
        android:onClick="giveClue" />

NOTE: I don't want to use different method for the

ACTIVITY CLASS:

public void giveClue(View view) {
        gameAdapter.giveClue(game);
    }

My problem is that I want to disable the button that was clicked.I don't want to use different method for each button. Is it possible to determine which button was clicked so I can disable it.

Thank you.

Implement one method as follows which gets the id's of child objects of layout

public static void ButtonBar(final Activity a) {
    //if linear instantiate LinearLayout, if RelativeLayout instantiate RelaytiveLayout
   final LinearLayout ll = (LinearLayout) a.findViewById(R.id.your_layout_id);
      for (int i = ll.getChildCount() - 1; i >= 0; i--) {

        View v = ll.getChildAt(i);

        v.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {

                switch (v.getId()) {
                case R.id.ImageButton1:
                    //disable here
                    break;
                case R.id.ImageButton2:
            //disable here                      
            break;
                    case R.id.ImageButton3:
            //disable here                      
            break;

                }}});
    }
  }

In giveClue method just call the above method..

public void giveClue(View view) {
       ButtonBar(this);
          // gameAdapter.giveClue(game);

}

I think this may works..

Have your class implement `View.OnClickListener', like

public class MyActivity extends Activity implements View.OnClickListener {

Button button1, button2, button3;

@Override
public void onCreate(Bundle bundle) {
    super.onCreate();

    ...

    button1 = (Button) findViewById(R.id.button1);
    button2 = (Button) findViewById(R.id.button2);
    button3 = (Button) findViewById(R.id.button3);

    button1.setOnClickListener(this);
    button2.setOnClickListener(this);
    button3.setOnClickListener(this);
    }

     @Override
      public void onClick(View v) {
       switch(v.getId()) {
         case R.id.button1:
       // do stuff;
       break;
       case R.id.button2:
       // do stuff;
       break;
   ...
       }
      }

As from: Android OnClickListener - identify a button

You will learn the way to do it, in an easy way, is:

public class Mtest extends Activity {
  Button b1;
  Button b2;
  public void onCreate(Bundle savedInstanceState) {
    ...
    b1 = (Button) findViewById(R.id.b1);
    b2 = (Button) findViewById(R.id.b2);
    b1.setOnClickListener(myhandler1);
    b2.setOnClickListener(myhandler2);
    ...
  }
  View.OnClickListener myhandler1 = new View.OnClickListener() {
    public void onClick(View v) {
      // it was the 1st button
    }
  }
  View.OnClickListener myhandler2 = new View.OnClickListener() {
    public void onClick(View v) {
      // it was the 2nd button
    }
  }
}

Or, if you are working with just one clicklistener, you can do:

View.OnClickListener myOnlyhandler = new View.OnClickListener() {
  public void onClick(View v) {
      if( b1.getId() == ((Button)v).getId() ){
          // it was the first button
      }
      else if( b2.getId() == ((Button)v).getId() ){
          // it was the second button
      }
  }
}

Though, I don't recommend doing it that way since you will have to add an if for each button you use. That's hard to maintain.

Since the view that you get as an argument to onClick represents the view that was clicked, you can just call setEnabled(false) to disable the button.

public void giveClue(View view) {
    ((Button)view).setEnabled(false);  // disable button
}

Like that..

public void giveClue(View view) {
    if( b1.getId() == view.getId() ){
      // it was the first button
    }
    else if( b2.getId() == view.getId() ){
      // it was the second button
    }
  }
