How to write a TextView in a determined coordinates of the screen? (frame layout)

You might want to add an AbsoluteLayout overlay, calculate the absolute position on the screen using screen dimensions and set the position of the view accordingly.

Edit

Since the AbsoluteLayout is deprecated, you can use the following technique to position the text in a RelativeLayout:

text = (TextView) findViewById(R.id.text);

RelativeLayout.LayoutParams position = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

position.leftMargin = 20;
position.topMargin  = 40;

text.setLayoutParams(position);
