Set textview focus color programmatically / change focus color in themes


1) Is it possible to set a TextView's color programmatically? If so what's the easiest way?

I want something else other that the default 4.0+ light-blue color.

I found and tried the following code without success:

StateListDrawable states = new StateListDrawable();
states.addState(new int[] {android.R.attr.state_pressed}, new ColorDrawable(0x1A000000));
states.addState(new int[] {android.R.attr.state_focused}, new ColorDrawable(0x1A000000));

if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    tv.setBackgroundDrawable(states);
} else {
    tv.setBackground(states);
}

I do not wish any XML involved.

2) Can I change the focus color in my themes in general? If yes how?

XML is obviously fine here.


Solution

  • You can use ColorStateList, to specify the state color programmatically.

        int[][] states = new int[][] {
            new int[] { android.R.attr.state_pressed}, // pressed
            new int[] { android.R.attr.state_focused}, // focused
            new int[] { android.R.attr.state_enabled} // enabled
        };
    
        int[] colors = new int[] {
            Color.parseColor("#008000"), // Green
            Color.parseColor("#0000FF"), // Blue
            Color.parseColor("#FF0000")  // Red
        };
        
        ColorStateList list = new ColorStateList(states, colors);
        textView.setTextColor(list);        
        textView.setClickable(true);
        textView.setFocusableInTouchMode(true);
