本文介绍了如何在Android中获取statusBarHeight、titleBarHeight以及DisplayWidth和DisplayHeight。通过调用getResources().getIdentifier获取statusBarHeight，使用getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop()计算TitleBar高度，利用getWindowManager().getDefaultDisplay().getHeight()和自定义方法获取屏幕显示区域高度。

        requestWindowFeature(Window.FEATURE_NO_TITLE);
//       requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
       setContentView(R.layout.activity_main);
//       getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title);

   a. 得到statusBarHeight：
       public static int getStatusBarHeight(Context context) {
       int result = 0;
       int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen",
                "android");
       if (resourceId > 0) {
       result = context.getResources().getDimensionPixelSize(resourceId);
       }
       return result;
       }

   b.得到TitleBar高度
            int contentViewTop = getWindow().findViewById(Window.ID_ANDROID_CONTENT).getTop();
       int titleBarHeight = contentViewTop - statusBarHeight;

   c.得到屏幕可显示区域高度
   public static int getDisplayHeight(Context context) {
        Rect frame = new Rect();
        ((Activity)context).getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
        int statusBarHeight = getStatusBarHeight(context);
   //得到屏幕的整个高度
        int mFullDisplayHeight = ((Activity)context).getWindowManager().getDefaultDisplay()
                .getHeight();

   //得到可显示屏幕高度
        int mDisplayHeight = mFullDisplayHeight - statusBarHeight - titleBarHeight;
        // Log.d("TEST", "status bar height:" + statusBarHeight);
        // Log.d("TEST", "mFullDisplayHeight====" + mFullDisplayHeight);
        return mDisplayHeight;
    }

        public static void getDisplaySize(Context context) {
        Display display = ((Activity)context).getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        int width = size.x;
        int height = size.y;
        Log.d("Display sise", "width:" + width + "---height:" + height);
    }


   private void getScreenSize() {
        DisplayMetrics metric = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metric);
        int screenWidth = metric.widthPixels;
        int screenHeight = metric.heightPixels;
        Log.d("Screen", "width: =" + screenWidth + " Height: =" + screenHeight);
    }
