在Android中是否有办法获得软按钮栏和状态栏的大小?或者一种方法去获得没有这两个高度的屏幕高度? (它们并不总是相同的,例如看看nexus 7)
答案 0 :(得分:33)
状态栏的高度
状态栏的高度取决于屏幕尺寸,例如,在屏幕尺寸 240 X 320 的设备中,状态栏高度 20px ,对于设备屏幕尺寸为 320 X 480 ,状态栏高度 25px ,对于 480 x 800 的设备,状态栏高度必须为38px
因此我建议使用此脚本获取状态栏高度
Rect rectangle = new Rect();
Window window = getWindow();
window.getDecorView().getWindowVisibleDisplayFrame(rectangle);
int statusBarHeight = rectangle.top;
int contentViewTop = window.findViewById(Window.ID_ANDROID_CONTENT).getTop();
int titleBarHeight= contentViewTop - statusBarHeight;
Log.i("*** Value :: ", "StatusBar Height= " + statusBarHeight + " , TitleBar Height = " + titleBarHeight);
要获取活动的onCreate()
方法的状态栏的高度,请使用以下方法:
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
软键按钮栏
此方法对于在Android KitKat(4.4)中设置布局填充非常有用。使用此功能,您可以避免在布局上重叠的软按钮栏。
getRealMetrics
方法仅适用于API 17和+
@SuppressLint("NewApi")
private int getSoftButtonsBarHeight() {
// getRealMetrics is only available with API 17 and +
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int usableHeight = metrics.heightPixels;
getWindowManager().getDefaultDisplay().getRealMetrics(metrics);
int realHeight = metrics.heightPixels;
if (realHeight > usableHeight)
return realHeight - usableHeight;
else
return 0;
}
return 0;
}

对我来说,在android note 10中,我需要按dimen获取导航栏的高度:
fun getSoftNavigationBarSize(resources: Resources): Int {
var result = 0
val resourceId: Int = resources.getIdentifier("navigation_bar_height", "dimen", "android")
if (resourceId > 0) {
result = resources.getDimensionPixelSize(resourceId)
}
return result
}
答案 2 :(得分:0)
我知道这已经得到了回答,但我刚刚发现这个解决方案似乎比其他解决方案更容易。我只在底部按钮栏上尝试过。不过,我很确定它对状态栏的工作方式相同。
view.rootWindowInsets?.let { inset ->
Log.e("XXX", "button bar height: ${inset.systemWindowInsetBottom}")
}
注意:此时您需要一个附加到窗口的视图。

private void getStatusAndNavigationBarsHeight() {
float deviceDensity = getResources().getDisplayMetrics().density;
float statusHeight = 0;
float navigationHeight = 0;
Resources myResources = getApplicationContext().getResources();
int idStatusBarHeight = myResources.getIdentifier( "status_bar_height", "dimen", "android");
statusHeight = idStatusBarHeight > 0 ? getResources().getDimensionPixelSize(idStatusBarHeight)/deviceDensity : 0;
statusHeight = Math.round(statusHeight);
Log.d("StatusBar Height(dp):", String.valueOf(statusHeight));
int idNavigationBarHeight = myResources.getIdentifier("navigation_bar_height", "dimen", "android");
navigationHeight = idNavigationBarHeight > 0 ? getResources().getDimensionPixelSize(idNavigationBarHeight)/deviceDensity : 0;
navigationHeight = Math.round(navigationHeight);
Log.d("Navigation Bar Height(dp):", String.valueOf(navigationHeight));
}
