Question

This is to create a greeting card application and here i have to change the background color of the view( which is the background of the card) when a button is clicked. When i click the button labeled red the view should change it’s color to red. and so on. Can someone help me with this?

 public void myClickHandler(View view) {
    switch (view.getId()) {
      case R.id.btn1:

        layout= (FrameLayout) findViewById(R.id.laidout);
        layout.setBackgroundColor(Color.RED);
        break;

        }

Answer 1

You should write your code in onClick(View view) method instead of myClickHandler().And the id “btn1” should be the id name which you declared in your xml file.
