you can dynamically set width and height of textview by

private TextView mTxtView;
private int screenWidth, screenHeight;
Display display = getWindowManager().getDefaultDisplay(); 
    screenWidth = display.getWidth();
    screenHeight = display.getHeight();


LayoutParams params = mTxtView.getLayoutParams();
    params.width = screenWidth-30;
    mTxtView.setLayoutParams(params);
