華為以及nexus一些機(jī)型的NavigationBar存在遮擋App頁(yè)面的問(wèn)題
1、遮擋布局 布局內(nèi)加上android:fitsSystemWindows="true" 就可以了。
網(wǎng)上還有一種辦法是
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
getWindow().getDecorView().setSystemUiVisibility(View.STATUS_BAR_HIDDEN);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_SHOW_FULLSCREEN);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
這種辦法一開(kāi)始是會(huì)隱藏，但是點(diǎn)擊布局，navicationBar又出現(xiàn)了。
2、遮擋控件（比如底部彈窗）
這個(gè)時(shí)候我們可以采用下面這種辦法來(lái)解決
public staticPointgetNavigationBarSize(Context context) {
Point appUsableSize =getAppUsableScreenSize(context);
Point realScreenSize =getRealScreenSize(context);
// navigation bar on the right
if(appUsableSize.x< realScreenSize.x) {
return newPoint(realScreenSize.x- appUsableSize.x,appUsableSize.y);
}
// navigation bar at the bottom
if(appUsableSize.y< realScreenSize.y) {
return newPoint(appUsableSize.x,realScreenSize.y- appUsableSize.y);
}
// navigation bar is not present
return newPoint();
}
public staticPointgetAppUsableScreenSize(Context context) {
WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Display display = windowManager.getDefaultDisplay();
Point size =newPoint();
display.getSize(size);
return size;
}
public staticPointgetRealScreenSize(Context context) {
WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
Display display = windowManager.getDefaultDisplay();
Point size =newPoint();
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;
}
