这是我用来获取导航栏大小的代码。它的高度将在Point.y
感谢this answer
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,我有,因为我想ResideMenu添加到我的应用程序使用此fonction,但最终得到一个奇怪的由于导航栏的原因,我的应用程序底部出现了空边距。
所以我编辑这fonction通过ResideMenu加入这样的:
@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;
}
希望这将帮助你。
你想达到什么目的?说一些关于这方面的细节。可能你根本不需要计算导航栏高度。 –
@Jabbar_Jigariyo当用户有一个导航栏(我使用透明导航栏)时,我需要设置填充到包含ImageButtons和更多的底部视图 –
如果您使用透明导航栏,那么为什么会需要隐藏它?对于那些有导航栏的设备,它已经是透明的了,对于那些有物理按钮的设备,不会有导航栏。对 ? –
