Can't hide Bottom Sheet, Android
提问by alb
I'm having problems with my bottom-sheetbecause when I open the activity it is on, blocking the view
我的底部工作表有问题，因为当我打开活动时，它会挡住视图
This happens, I think, because of the XML attribute declaring the bottom-sheetwith 350dp of height:
我认为发生这种情况是因为 XML 属性声明了具有 350dp 高度的底表：
<android.support.v4.widget.NestedScrollView
android:id="@+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="350dp"
android:background="?android:attr/windowBackground"
android:clipToPadding="true"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
The thing is, I can't change that value to 0dp because the next time when I try to open the bottom-sheet, there is no bottom-sheet, because the height is 0dp, so it won't show anything. My question is, is there a way to declare the bottom-sheetoff? (I've tried to setState to STATE_COLLAPSED but didn't work). Bellow is the java code that interacts with the Bottom Sheet. JAVA:
问题是，我无法将该值更改为 0dp，因为下次当我尝试打开bottom-sheet 时，没有bottom-sheet，因为高度是 0dp，所以它不会显示任何内容。我的问题是，有没有办法声明底部工作表？（我试图将 setState 设置为 STATE_COLLAPSED 但没有奏效）。Bellow 是与Bottom Sheet 交互的java 代码。爪哇：
View bottomSheet = findViewById( R.id.bottom_sheet );
mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
mBottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_COLLAPSED) {
//mBottomSheetBehavior.setPeekHeight(0);
//mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
//mBottomSheetBehavior.isHideable();
}
}
@Override
public void onSlide(View bottomSheet, float slideOffset) {
}
});

first you have to add the attribute
首先你必须添加属性
app:behavior_hideable="true"
in your
在你的
<android.support.v4.widget.NestedScrollView
android:id="@+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="350dp"
android:background="?android:attr/windowBackground"
android:clipToPadding="true"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
And then you can hide the bottom sheet using
然后您可以使用隐藏底部工作表
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_HIDDEN)
and not
并不是
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED)
the state COLLAPSED is between HIDDEN and EXPANDED and his heigth must be specified by the attribute:
COLLAPSED 状态介于 HIDDEN 和 EXPANDED 之间，其高度必须由属性指定：
app:behavior_peekHeight="200dp"

Write this:
写这个：
mBottomSheetBehavior.setPeekHeight(0);

In my case i was not able to hide the bottomsheet and it was placed on top of my view. I found out that animateLayoutChanges = "true"in my layout file was causing this issue.
在我的情况下，我无法隐藏底片，它被放置在我的视图顶部。我发现animateLayoutChanges = "true"在我的布局文件中导致了这个问题。

Inside onCreateadd these lines, it can hide the bottombar
在里面onCreate添加这些行，它可以隐藏底栏
mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
mBottomSheetBehavior.setHideable(true); //Important to add
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_HIDDEN); //Important to add

In my case I was using BottomSheetDialog.
就我而言，我使用的是BottomSheetDialog.
app:behavior_hideable- attribute is used to determine if our bottom sheet will hide when it is swiped down. In other words bottom sheet top be off screen, if the peek height isn't set.
app:behavior_hideable- 属性用于确定我们的底部工作表在向下滑动时是否会隐藏。换句话说，如果未设置窥视高度，则底部工作表顶部不在屏幕上。
app:behavior_peekHeight- attribute value used to represent how much pixels the bottom sheet will be visible.
app:behavior_peekHeight- 用于表示底部工作表可见的像素数的属性值。
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/bottom_sheet_container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="10dp"
android:orientation="vertical"
android:background="@color/colorPrimaryDerived"
app:layout_behavior="@string/bottom_sheet_behavior"
app:behavior_hideable="true"
app:behavior_peekHeight="0dp"> ........... </LinearLayout>
I set the peekHeight to 50dp. And peek height has nothing to do with the bottomSheet layout height itself which I set 200dp (for example only).
我将 peekHeight 设置为 50dp。并且 peek height 与我设置为 200dp 的 bottomSheet 布局高度本身无关（仅作为示例）。
You can view the changes in your XML viewer if the bottom sheet is expanded, if so add the app:behavior_peekHeight = 0dpfrom the xml layout and it will hide and also inform you of the current state.
如果底部工作表被展开，您可以在 XML 查看器中查看更改，如果是这样，app:behavior_peekHeight = 0dp则从 xml 布局添加它，它会隐藏并通知您当前状态。

You can manually hide that bottom sheet by setting the visibility of the parent linear layout to gone put this line in your code when you want
您可以通过将父线性布局的可见性设置为在需要时将此行放入代码中来手动隐藏该底部工作表
if (confirmLayoutBehaviour.getState() != BottomSheetBehavior.STATE_EXPANDED) {
//todo hide your bottom sheet if its already open
confirmLayout.setVisibility(View.GONE);
} else {
//set it to visible if its not open
confirmLayout.setVisibility(View.VISIBLE);
}
if (confirmLayoutBehaviour.getState() != BottomSheetBehavior.STATE_EXPANDED) {
//todo hide your bottom sheet if its already open
confirmLayout.setVisibility(View.GONE);
} else {
//set it to visible if its not open
confirmLayout.setVisibility(View.VISIBLE);
}
it worked for me please try it
它对我有用，请试试
