如何允许BottomSheetDialog进行外部触摸? [英] How to Allow outside touch for BottomSheetDialog?

问题描述

我正在使用BottomSheetDialogFragment，我的要求是创建底部"菜单， 如果我在片段区域之外单击，它应该不取消对话框，并且应该保留.

问题: 片段外部"的事件应传播到较低的片段视图/片段.

我已经在下面尝试过(不适用于BottomDialogFragment): 允许DialogFragment进行外部触摸

要停止对话框，请尝试以下操作(我在BottomDialogFragment的onStart()中调用setCancelable(boolean)):

@Override
    public void setCancelable(boolean cancelable) {
        super.setCancelable(cancelable);

        BottomSheetDialog dialog = (BottomSheetDialog) getDialog();
        dialog.setCanceledOnTouchOutside(cancelable);

        View bottomSheetView = dialog.getWindow().getDecorView().findViewById(R.id.design_bottom_sheet);
        BottomSheetBehavior.from(bottomSheetView).setHideable(cancelable);
    }

此解决方案解决了这个问题，但将其整合到了一起更多问题.即所有的actionMode事件都不被导航，而其他所有应用程序事件都被导航.

这是我对此问题的最佳解决方法解决方案

解决方案

您应该使用android.support.design.widget.BottomSheetBehavior.

但是如果您想在其他课程中使用bottomSheet，我建议您使用Fragment，并在此fragment中打开您的bottomSheet

以这种方式打开您的片段 .

然后在您的片段中，使用以下代码打开bottomSheet:

在onInitViews

var mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheetCoordinatorLayout)
mBottomSheetBehavior!!.state = BottomSheetBehavior.STATE_HIDDEN

mBottomSheetBehavior!!.setBottomSheetCallback(object : BottomSheetBehavior.BottomSheetCallback() {
     override fun onStateChanged(bottomSheet: View, newState: Int) {
          when (newState) {
             BottomSheetBehavior.STATE_HIDDEN -> {
                  fragmentManager?.popBackStack()
             }
             //BottomSheetBehavior.STATE_COLLAPSED -> "Collapsed"
             //BottomSheetBehavior.STATE_DRAGGING -> "Dragging..."
             //BottomSheetBehavior.STATE_EXPANDED -> "Expanded"
             //BottomSheetBehavior.STATE_SETTLING -> "Settling..."
           }
      }

      override fun onSlide(bottomSheet: View, slideOffset: Float) {
          //text_view_state!!.text = "Sliding..."
      }
})

您的layout应该是这样的:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layoutDirection="ltr">

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/bottomSheetCoordinatorLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:behavior_hideable="true"
        app:behavior_peekHeight="55dp"
        app:layout_behavior="@string/bottom_sheet_behavior">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/top_radius_primary_color"
            android:paddingStart="@dimen/material_size_32"
            android:paddingEnd="@dimen/material_size_32">

        </RelativeLayout>
    </android.support.design.widget.CoordinatorLayout>
</android.support.design.widget.CoordinatorLayout>

I am working on BottomSheetDialogFragment my requirement is to create Bottom menu, Where if I click outside fragment area it should not cancel the Dialog and should persist.

ISSUE: And Event outside the Fragment should propagate to the lower fragment view/fragment.

I have already tried below(doesn't work for BottomDialogFragment): Allow outside touch for DialogFragment

To stop the dialog cancel i tried Below(i call setCancelable(boolean) in onStart() of BottomDialogFragment):

@Override
    public void setCancelable(boolean cancelable) {
        super.setCancelable(cancelable);

        BottomSheetDialog dialog = (BottomSheetDialog) getDialog();
        dialog.setCanceledOnTouchOutside(cancelable);

        View bottomSheetView = dialog.getWindow().getDecorView().findViewById(R.id.design_bottom_sheet);
        BottomSheetBehavior.from(bottomSheetView).setHideable(cancelable);
    }

EDIT: Found it the hard way there is no other go then using Coordinate layout.The best solution for BottomSheetDialog is here

• This Solution solve's the issue but bring's in one more issue. i.e all the actionMode event's are not navigated while all other app event's are.
• And this is my best solution to the problem

解决方案

you should use android.support.design.widget.BottomSheetBehavior.

but if you want to have a bottomSheet in other class I suggest you use a Fragment and in this fragment open your bottomSheet

open your fragment in this way.

And in your fragment, open your bottomSheet in the following code:

in onInitViews

var mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheetCoordinatorLayout)
mBottomSheetBehavior!!.state = BottomSheetBehavior.STATE_HIDDEN

mBottomSheetBehavior!!.setBottomSheetCallback(object : BottomSheetBehavior.BottomSheetCallback() {
     override fun onStateChanged(bottomSheet: View, newState: Int) {
          when (newState) {
             BottomSheetBehavior.STATE_HIDDEN -> {
                  fragmentManager?.popBackStack()
             }
             //BottomSheetBehavior.STATE_COLLAPSED -> "Collapsed"
             //BottomSheetBehavior.STATE_DRAGGING -> "Dragging..."
             //BottomSheetBehavior.STATE_EXPANDED -> "Expanded"
             //BottomSheetBehavior.STATE_SETTLING -> "Settling..."
           }
      }

      override fun onSlide(bottomSheet: View, slideOffset: Float) {
          //text_view_state!!.text = "Sliding..."
      }
})

And your layout should be like this:

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layoutDirection="ltr">

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/bottomSheetCoordinatorLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:behavior_hideable="true"
        app:behavior_peekHeight="55dp"
        app:layout_behavior="@string/bottom_sheet_behavior">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/top_radius_primary_color"
            android:paddingStart="@dimen/material_size_32"
            android:paddingEnd="@dimen/material_size_32">

        </RelativeLayout>
    </android.support.design.widget.CoordinatorLayout>
</android.support.design.widget.CoordinatorLayout>
