Anyone can help? Thank you four your time and help.

Answer 1

First, You can't split a TextView. But you can achieve by setting a right image as android:setDrawableBottom="yourImage"

Answer 2

You are able to customise a View in Android by overrideing the onDraw method of that View .

Something you might consider would be:

@Override
protected void onDraw(Canvas canvas) {
    // paint a line through the centre
    Paint paint = new Paint();
    canvas.drawLine(0, canvas.getWidth(), canvas.getHeight()/2, 
                    canvas.getHeight()/2, paint);
    super.onDraw(canvas);
}

This would draw a line through the centre of the View (in your case a TextView ). You could use the same method for your 10%/90% colouring.

Eg.

@Override
protected void onDraw(Canvas canvas) {
    // paint a region blue
    Paint paint = new Paint();
    paint.setColor(Color.BLUE);//or whatever colour you want
    canvas.drawRect(0, canvas.getHeight()/10, canvas.getWidth(),
                    canvas.getHeight(), paint)
    super.onDraw(canvas);
}

Draw rect takes the arguments:

canvas.drawRect(left, top, right, bottom, paint)

And there are alternatives where you can pass in the actual drawing Rectangle etc.
