Display disp = getWindowManager().getDefaultDisplay();
        int screenWidth = disp.getWidth();
        int screenHeight = disp.getHeight();

設置控件寬高

LinearLayout.LayoutParams l = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT);
l.width = 100;
l.height = 200;
