好吧,状态栏的高度取决于屏幕的大小,例如在一个设备中
对于240 X 320屏幕尺寸的设备,状态栏高度为20px,对于320 X 480屏幕尺寸的设备,状态栏高度为25px,对于480 X 800设备,状态栏高度必须为38px
所以我建议使用这个脚本来获取状态栏的高度
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("*** Elenasys :: ", "StatusBar Height= " + statusBarHeight + " , TitleBar Height = " + titleBarHeight);
(旧方法)在你的活动的onCreate()方法上获取状态栏的高度,使用这个方法:
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
private static final int LOW_DPI_STATUS_BAR_HEIGHT = 19;
private static final int MEDIUM_DPI_STATUS_BAR_HEIGHT = 25;
private static final int HIGH_DPI_STATUS_BAR_HEIGHT = 38;
在onCreate内部:
DisplayMetrics displayMetrics = new DisplayMetrics();
((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getMetrics(displayMetrics);
int statusBarHeight;
switch (displayMetrics.densityDpi) {
case DisplayMetrics.DENSITY_HIGH:
statusBarHeight = HIGH_DPI_STATUS_BAR_HEIGHT;
break;
case DisplayMetrics.DENSITY_MEDIUM:
statusBarHeight = MEDIUM_DPI_STATUS_BAR_HEIGHT;
break;
case DisplayMetrics.DENSITY_LOW:
statusBarHeight = LOW_DPI_STATUS_BAR_HEIGHT;
break;
default:
statusBarHeight = MEDIUM_DPI_STATUS_BAR_HEIGHT;
}
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ViewGroup decorView = (ViewGroup) this.getWindow().getDecorView();
decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
if (Build.VERSION.SDK_INT >= 16) {
decorView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
} else {
// Nice one, Google
decorView.getViewTreeObserver().removeGlobalOnLayoutListener(this);
}
Rect rect = new Rect();
decorView.getWindowVisibleDisplayFrame(rect);
rect.top; // This is the height of the status bar
}
}
}
<!-- Height of the status bar -->
<dimen name="status_bar_height">24dp</dimen>
<!-- Height of the bottom navigation / system bar. -->
<dimen name="navigation_bar_height">48dp</dimen>
