这是我用来获取导航栏大小的代码.它的高度将在Point.y中

public static Point getNavigationBarSize(Context context) {

Point appUsableSize = getAppUsableScreenSize(context);

Point realScreenSize = getRealScreenSize(context);

// navigation bar on the right

if (appUsableSize.x < realScreenSize.x) {

return new Point(realScreenSize.x - appUsableSize.x, appUsableSize.y);

}

// navigation bar at the bottom

if (appUsableSize.y < realScreenSize.y) {

return new Point(appUsableSize.x, realScreenSize.y - appUsableSize.y);

}

// navigation bar is not present

return new Point();

}

public static Point getAppUsableScreenSize(Context context) {

WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);

Display display = windowManager.getDefaultDisplay();

Point size = new Point();

display.getSize(size);

return size;

}

public static Point getRealScreenSize(Context context) {

WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);

Display display = windowManager.getDefaultDisplay();

Point size = new Point();

if (Build.VERSION.SDK_INT >= 17) {

display.getRealSize(size);

} else if (Build.VERSION.SDK_INT >= 14) {

try {

size.x = (Integer) Display.class.getMethod("getRawWidth").invoke(display);

size.y = (Integer) Display.class.getMethod("getRawHeight").invoke(display);

} catch (IllegalAccessException e) {} catch (InvocationTargetException e) {} catch (NoSuchMethodException e) {}

}

return size;

}

编辑：要回答你的问题,我必须使用此功能,因为我想将ResideMenu添加到我的应用程序,但由于导航栏,我的应用程序底部结束了一个奇怪的空边距.

所以我编辑了Re​​sideMenu添加的这个函数,如下所示：

@Override

protected boolean fitSystemWindows(Rect insets) {

// Applies the content insets to the view's padding, consuming that content (modifying the insets to be 0),

// and returning true. This behavior is off by default and can be enabled through setFitsSystemWindows(boolean)

// in API14+ devices.

int bottomPadding = insets.bottom;

Point p = getNavigationBarSize(getContext());

if (Build.VERSION.SDK_INT >= 21 && p.x != 0) {

Resources resources = getContext().getResources();

int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");

if (resourceId > 0) {

bottomPadding += resources.getDimensionPixelSize(resourceId);

}

}

this.setPadding(viewActivity.getPaddingLeft() + insets.left, viewActivity.getPaddingTop() + insets.top,

viewActivity.getPaddingRight() + insets.right, viewActivity.getPaddingBottom() + bottomPadding);

insets.left = insets.top = insets.right = insets.bottom = 0;

return true;

}

希望能帮到你.
