我需要 BottomSheet
停在两个位置。我有以下 BottomSheet
代码。
<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:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
....
</RelativeLayout>
<FrameLayout
android:id="@+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/white"
android:minHeight="1000dp"
android:orientation="vertical">
....
</LinearLayout>
</ScrollView>
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
和
View bottomSheet = coordinatorLayout.findViewById(R.id.bottom_sheet);
final BottomSheetBehavior behavior = BottomSheetBehavior.from(bottomSheet);
behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
// React to state change
Log.e("onStateChanged", "onStateChanged:" + newState);
if (newState == BottomSheetBehavior.STATE_EXPANDED) {
behavior.setPeekHeight(600);
showAgain.setVisibility(View.GONE);
mMap.getUiSettings().setScrollGesturesEnabled(false);
} else if (newState == BottomSheetBehavior.STATE_COLLAPSED) {
if (behavior.getPeekHeight() == 600) {
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
behavior.setPeekHeight(80);
mMap.getUiSettings().setScrollGesturesEnabled(false);
} else if (behavior.getPeekHeight() == 80) {
showAgain.setVisibility(View.VISIBLE);
mMap.getUiSettings().setScrollGesturesEnabled(true);
}
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
// React to dragging events
Log.e("onSlide", "onSlide " + slideOffset);
}
});
behavior.setPeekHeight(600);
除一件事外,这段代码工作正常。第一次我必须向上滚动 BottomSheet
然后我可以向下滚动它。我无法直接向下滚动工作表。
我们将不胜感激。
最佳答案
我不知道这是否能解决您的问题,但我通过替换 BottomSheet
中的BottomSheet
带有 NestedScrollView
。
关于java - BottomSheet 的滚动问题 - Android,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/37655712/
