Switching Color Of Buttons After Onclick

i have several buttons.i want when i click on any of the buttons its color should be changed and other buttons should remain the same.Next time when i click on other button its col

Solution 1:

try

button.setBackgroundColor( android.graphics.Color.GREEN);

Solution 2:

try this the problem in your code is you are putting a color filter on the button's bg property and it will remain even if you change the bg instead set the filter on the imgand set it as bg fr btn

 switch(v.getId())
    {
    case R.id.bt1:
        Drawable d=b11.getBackground();
        d.setColorFilter(Color.CYAN,PorterDuff.Mode.MULTIPLY);

        b11.setBackgroundDrawable(d);
        b12.setBackgroundResource(android.R.drawable.btn_default);
    break;

    case R.id.bt2:
    //b2.getBackground().setColorFilter(Color.CYAN,PorterDuff.Mode.MULTIPLY);
    Drawable dd=b12.getBackground();
    dd.setColorFilter(Color.CYAN,PorterDuff.Mode.MULTIPLY);

    b12.setBackgroundDrawable(dd);
    b11.setBackgroundResource(android.R.drawable.btn_default);
    break;
    }

Solution 3:

"next time everything is going wrong both the buttons remain in the CYAN color" because when you click other button, you are only changing other button background but color remained the same I guess. You have to change background color also.

switch(v.getId())
{
case R.id.bt1:
bt11.getBackground().setColorFilter(Color.CYAN,PorterDuff.Mode.Multiple);
bt12.setBackgroundResource(android.R.drawable.btn_default);
bt12.setBackgroundColor(Black);
break;

case R.id.bt2:
bt12.getBackground().setColorFilter(Color.CYAN,PorterDuff.Mode.Multiple);
bt11.setBackgroundResource(android.R.drawable.btn_default);
bt11.setBackgroundColor(Black);
break;
}
