Question

Who to capture the click of any button?

final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new View.OnClickListener() {
       public void onClick(View v) {
            Toast.makeText(WHKConversorActivity.this, "Hello World", Toast.LENGTH_SHORT).show();                    
       }
 });

this is a click on button1 but i need an function for all buttons :-/ .
Example in javascript:

$('button').click(function(){
    alert($(this).val());
});

Thanks 🙂

If you want all your buttons to do exactly the same thing (which is unlikely) you could bind the same click listener to each button. Eg:

final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(mGlobalClick);

final Button button2 = (Button) findViewById(R.id.button2);
button2.setOnClickListener(mGlobalClick);

... ect

OnClickListener mGlobalListener = new OnClickListener() {

    @Override
    public void onClick(View v) {
            //Stuff
            }
};

Or if you want a each button to do something different, but still need some sort of reapeated function for each, you could put that part of the code in a seperate method and reference it in every click listener

public void GlobalStuff(){
     //Stuff
}

OnClickListener mSpecificListener = new OnClickListener() {

    @Override
    public void onClick(View v) {
            GlobalStuff();
            //More Stuff
            }
};
