获得控件的高度

1.获取屏幕的宽高

//        (1)
        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        int widthPixels = dm.widthPixels;
        int heightPixels = dm.heightPixels;
//        (2)
        Point point = new Point();
        getWindowManager().getDefaultDisplay().getSize(point);
        int x = point.x;
        int y=point.y;
//        (3)
        int height = getWindowManager().getDefaultDisplay().getHeight();
        int width = getWindowManager().getDefaultDisplay().getWidth();
//        (4)
        int heightPixels1 = getResources().getDisplayMetrics().heightPixels;
        int widthPixels2 = getResources().getDisplayMetrics().widthPixels;

int screenHeight = getResources().getDisplayMetrics().heightPixels;
        LayoutParams params = mMineDataPager.getLayoutParams();
        params.height=screenHeight/2;
        mMineDataPager.setLayoutParams(params);
