MyActivity.java

publicclassMyActivityextendsActivityimplementsView.OnClickListener{


    private Button button1;
    private Button button2;
    private Button button3;
    private Button button4;
    @Overrideprotected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        button1 = (Button) findViewById(R.id.button1);
        button2 = (Button) findViewById(R.id.button2);
        button3 = (Button) findViewById(R.id.button3);
        button4 = (Button) findViewById(R.id.button4);

        button1.setOnClickListener(this);
        button2.setOnClickListener(this);
        button3.setOnClickListener(this);
        button4.setOnClickListener(this);

    }

    @Overridepublic void onClick(View v) {
        switch (v.getId()){
            case R.id.button1:
                Toast.makeText(this,"Button 1 click",Toast.LENGTH_SHORT).show();
                break;
            case R.id.button2:
                Toast.makeText(this,"Button 2 click",Toast.LENGTH_SHORT).show();
                break;
            case R.id.button3:
                Toast.makeText(this,"Button 3 click",Toast.LENGTH_SHORT).show();
                break;
            case R.id.button4:
                Toast.makeText(this,"Button 4 click",Toast.LENGTH_SHORT).show();
                break;
            default:
                break;
        }
    }
}

Solution 2:

You need to set tag to your views and set them to be clickable.

Later on you can get the id by view.gettag() inside this method

publicvoidonClick(View v){
int id = v.getTag();
    switch(id){
      case0:
      break;
      default:
      break;
    }
}

Solution 3:

You can try this:

parent.setOnClickListener(newOnClickListener(){

    @OverridepublicvoidonClick(View v) {
    ViewGroupparent= (ViewGroup)v;

        for(intindex=0; index < parent.getChildCount(); index++){
            Viewchild= parent.getChildAt(index);

        }
    }

});

Solution 4:

for every child

android:duplicateParentState="true"
