Android得到屏幕分辨率

private void getScreenSize(Context context) {
    DisplayMetrics dm = context.getResources().getDisplayMetrics();
    int screen_width = dm.widthPixels;
    int screen_height = dm.heightPixels;
    /** 手机的屏幕密度 */
    float density = dm.density;
    Log.i(TAG, "屏幕宽高：" + SCREEN_WIDTH + " X " + SCREEN_HEIGHT);
    Log.i(TAG, "屏幕分辨率:" + density);
    // 将像素转换成dp
    int CORNER_HEIGHT = (int) (CORNER_HEIGHT * density);/** 四个边角对应的长度 */
    int TEXT_SIZE = (int) (TEXT_SIZE * density);/** 字体大小 */
}
