使用22.2.1设计支持库和API 22(尚未在早期版本上测试过),我在切换片段时遇到状态栏填充问题。初始片段加载正常,但在片段事务处理后,状态栏填充消失,将所有视图推到他们不应该的位置。弹出后栈后,原始片段也会发生同样的事情。旋转设备可以固定它,就像打开软键盘一样(但仅限于纵向,而不是横向)。
main fragment on initial load or after rotation(desired)
main fragment after back pressed
other fragment after rotation or keyboard(desired)
主要片段:
// Days late
System.out.print("Days late: ");
int daysLate = in.nextInt();
// You will probably need to get rid of the new line character here
in.nextLine();
// Daily Fine
System.out.print("Daily fine: ");
double dailyFine = in.nextDouble();
// And here..
in.nextLine();
//daily fine calculation
double fine = daysLate * dailyFine;
第二个片段:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainFragment">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
style="@style/RecyclerView"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
style="@style/Fab"
android:src="@drawable/ic_person_add_white_24dp"
app:backgroundTint="@color/accent_dark"
app:borderWidth="2dp"/>
主题将windowDrawsSystemBarBackgrounds设置为true,将statusBarColor设置为透明。
答案 0 :(得分:7)
解决了它,感谢Chris Banes。
问题是它不知道窗口插入。您必须在onViewCreated中请求ApplicationInsets。
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
ViewCompat.requestApplyInsets(coordinatorLayout);
}
