When click the floating action button "+", the bottomsheet show up like this:
Here is the activity_task.xml file:
<?xml version="1.0" encoding="utf-8"?>

Everything seems OK, but when I click above the bottomsheet, it doesn't disappear totally as I expect:
What's wrong?
回答1:
"By attaching a BottomSheetBehavior to a child View of a
CoordinatorLayout(i.e., addingapp:layout_behavior=”android.support.design.widget.BottomSheetBehavior”), you’ll automatically get the appropriate touch detection to transition between five state...".Try changing yourLinear LayouttoFrame Layoutwill do.
Try to use like this.
<FrameLayout
android:id="@+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ff0000"
app:behavior_hideable="true"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<Button
android:id="@+id/buildProjectButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/buildProject" />
<Button
android:id="@+id/buildTaskButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/buildTask" />
</FrameLayout>
Modify your code as this.
View bottomSheet = findViewById(R.id.bottom_sheet);
BottomSheetBehavior bottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
bottomSheetBehavior.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) {
// Hide your state here.
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
// React to dragging events
Log.e("onSlide", "onSlide");
}
});
EDIT 1:
Bottom sheets behavior is not hideable by default. You need to add this.
bottomSheetBehavior.setHideable(true);
回答2:
You are using a Persistent bottom sheet, this type of bottom sheet responds mainly to drag events i.e. you have to close it by dragging it down. If you want a bottom sheet that responds to clicking outside the dialog, consider Modal bottom sheet.
Alternatively, you can also use the fab to toggle the state of the bottom sheet i.e onClick of the fab it should expand the sheet if collapsed or collapse it if expanded.
