How to add a common listener for all buttons (no intrusive)?

I try to play a sound when you press any application button.

How is a secondary intrusive way to add a listener to all buttons in an application?

Is it possible to add overwrite (and expand) the common Android receiver?

Thank.

You can set one listener for all buttons and can also identify the tag.

View.OnClickListener myClickLIstener= new View.OnClickListener() {
    public void onClick(View v) {
        String tag = (String) v.getTag();
        Log.e("","tag : "+tag)
       // your stuff
    }
};

tuning listeners ...

btn1.setOnClickListener(myClickLIstener);
btn1.setTag("btn1");
btn2.setOnClickListener(myClickLIstener);
btn2.setTag("btn2");

EDIT:

You are looking for ...

class superTop implements View.OnClickListener {

        @Override
        public void onClick(View v) {
            Log.e("", "onClick superTop");
        }

    }

    class NewClick extends superTop implements View.OnClickListener {

        @Override
        public void onClick(View v) {
            Log.e("", "onClick NewClick");

            super.onClick(v);

        }

    }

    findViewById(R.id.button1).setOnClickListener(new NewClick());

You can also call a listener ...

OR SIMPLY

class YourClass implements OnClickListener{
    buttonOne.setOnclickListener(this);
    buttonTwo.setOnclickListener(this);
    buttonThree.setOnclickListener(this);

    public void onClick(View v){
        //do your stuff;
    }
}

Or, if you want, make your custom button:

Class Yourbutton extends Button implements Button.OnClickListener{
    public Yourbutton(Context c) {
        super(c);
    }
    public Yourbutton(Context c,AttributeSet s){
        super(c,s);
    }
    public void onClick(View v){
        //do your stuff;
    }
}

So, now you can use Yorkbutton as a common button that performs common tasks.

, OnClickListener

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

onClick :

public void onClick(View view) {


    switch(view.getId()){

//here you need the id of the button i.e. its id in the xml file
    case R.id.button1:
        // do whatever you want button1 to do
        break;
    case R.id.button2:
        // do whatever you want button2 to do
        break;
    }
}

android:onClick. onClick :

<Button
[...]
android:onClick="handleButton"/>

<Button
[...]
android:onClick="handleButton"/>

java :

public void handleButton(View v){
// do some stuff
}

Listener, , , ,

View.OnClickListener yourClickListener = new View.OnClickListener() {
        public void onClick(View v) {
            //play the music
        }
    };


button1.setOnClickListener(yourClickListener);
button2.setOnClickListener(yourClickListener);
button3.setOnClickListener(yourClickListener);

, ,

<LinearLayout ...>
  <Button android:text="1" onClick="onButtonClicked" clickable="true" />
  <Button android:text="2" onClick="onButtonClicked" clickable="true" />
  <Button android:text="3" onClick="onButtonClicked" clickable="true" />
  <Button android:text="4" onClick="onButtonClicked" clickable="true" />
</LinearLayout>

, onClick , java- findViewById.

, ,

public void onButtonClicked(View v){
     // do whatever needs to be done. For example:
     Toast.makeText(getApplicationContext(), ((Button) v).getText() + " clicked", Toast.LENGTH_SHORT).show(); 
}

You do not need to repeat the same code for everyone. You can try the general receiver, for example:

private OnClickListener genericClickListener= new OnClickListener() { 
    public void Click(View v) {
            // do something
    } 
};

Then all you have to do is register all three buttons to use this genericClickListener. That is, inside onCreate(),

Button firstbtn  = (Button) findViewById(R.id.firstbtn); 
Button secondbtn = (Button) findViewById(R.id.secondbtn); 
Button thirdbtn  = (Button) findViewById(R.id.thirdbtn); 

firstbtn.setOnClickListener(genericClickListener);
secondbtn.setOnClickListener(genericClickListener);
thirdbtn.setOnClickListener(genericClickListener);

Third method

Create one function / method and onClick for all buttons calls the same Method/Function.
