狀態(tài)欄即statusBar装盯，導航欄即某些手機底部有返回鍵的虛擬鍵那一欄，叫navigationBar甲馋。

1. 獲取頂部statusBar高度

private int getStatusBarHeight() {
    Resources resources = mActivity.getResources();
    int resourceId = resources.getIdentifier("status_bar_height", "dimen","android");
    int height = resources.getDimensionPixelSize(resourceId);
    Log.v("dbw", "Status height:" + height);
    return height;
}

2. 獲取底部navigationBar高度

private int getNavigationBarHeight() {
    Resources resources = mActivity.getResources();
    int resourceId = resources.getIdentifier("navigation_bar_height","dimen", "android");
    int height = resources.getDimensionPixelSize(resourceId);
    Log.v("dbw", "Navi height:" + height);
    return height;
}

3. 獲取設備是否存在NavigationBar

//獲取是否存在NavigationBar
    public static boolean checkDeviceHasNavigationBar(Context context) {
        boolean hasNavigationBar = false;
        Resources rs = context.getResources();
        int id = rs.getIdentifier("config_showNavigationBar", "bool", "android");
        if (id > 0) {
            hasNavigationBar = rs.getBoolean(id);
        }
        try {
            Class systemPropertiesClass = Class.forName("android.os.SystemProperties");
            Method m = systemPropertiesClass.getMethod("get", String.class);
            String navBarOverride = (String) m.invoke(systemPropertiesClass, "qemu.hw.mainkeys");
            if ("1".equals(navBarOverride)) {
                hasNavigationBar = false;
            } else if ("0".equals(navBarOverride)) {
                hasNavigationBar = true;
            }
        } catch (Exception e) {

        }
        return hasNavigationBar;

    }

4. 在頁面未加載出來前埂奈，獲取控件的寬高

    view.post(new Runnable() {
       @Override
        public void run() {
           int viewWidth = view.getWidth();//view寬度
                int viewHeight = view.getHeight();//view高度
            }
    });

5. 獲取屏幕寬度

在頁面未加載出來前，直接通過getWidth()獲取的寬度為0定躏，即使你在onResume()方法中執(zhí)行這個方法也是一樣账磺。

    public static int getScreenWidth(Context context) {
        DisplayMetrics dm = context.getResources().getDisplayMetrics();
        return dm.widthPixels;
    }

6. 獲取屏幕高度

    public static int getScreenHeight(Context context) {
        DisplayMetrics dm = context.getResources().getDisplayMetrics();
        return dm.heightPixels;
    }
