如何禁用BottomSheetDialogFragment手指拖动？

我看到了类似的问题，但它们都是BottomSheet而不是BottomSheetDialogFragment。

Answer 1

创建MyActivity如下：

public class MyActivity extends AppCompatActivity {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);

        new MyBottomSheetFragment().show(getSupportFragmentManager(), "tag");
    }

    public static class MyBottomSheetFragment extends BottomSheetDialogFragment {

        @Override
        public void setupDialog(Dialog dialog, int style) {
            BottomSheetDialog bottomSheetDialog = (BottomSheetDialog) dialog;
            bottomSheetDialog.setContentView(R.layout.sample);

            try {
                Field behaviorField = bottomSheetDialog.getClass().getDeclaredField("behavior");
                behaviorField.setAccessible(true);
                final BottomSheetBehavior behavior = (BottomSheetBehavior) behaviorField.get(bottomSheetDialog);
                behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {

                    @Override
                    public void onStateChanged(@NonNull View bottomSheet, int newState) {
                        if (newState == BottomSheetBehavior.STATE_DRAGGING{ 
                            behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
                        }
                    }

                    @Override
                    public void onSlide(@NonNull View bottomSheet, float slideOffset) {
                    }
                });
            } catch (NoSuchFieldException e) {
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            }
        }
    }
}

R.layout.sample是一个简单的布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <View
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:background="#e479da" />

    <View
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:background="#798de4" />

    <View
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:background="#e4db79" />

</LinearLayout>

您将获得以下输出：

Answer 2

发布材料设计1.2.0之后，有一种更简单的方法来实现相同的目的。

https://developer.android.com/reference/com/google/android/material/bottomsheet/BottomSheetBehavior#setdraggable

从BottomSheetDialogFragment拨打电话时：

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        val bottomSheetDialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog
        bottomSheetDialog.setOnShowListener {
            val bottomSheet = bottomSheetDialog
                .findViewById<FrameLayout>(com.google.android.material.R.id.design_bottom_sheet)

            if (bottomSheet != null) {
                val behavior: BottomSheetBehavior<*> = BottomSheetBehavior.from(bottomSheet)
                behavior.isDraggable = false
            }
        }
        return bottomSheetDialog
    }

或具有样式：

    <style name="SomeStyle" parent="Theme.MaterialComponents.Light.BottomSheetDialog">
        <item name="behavior_draggable">false</item>
    </style>

然后在对话框片段的onCreate中：

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setStyle(DialogFragment.STYLE_NORMAL, R.style.SomeStyle)
    }

Answer 3

我的版本。它运作完美。

class FragMenuBDrawer : BottomSheetDialogFragment() {

    ...

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        val dialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog

        dialog.setOnShowListener {
            val bottomSheet = (it as BottomSheetDialog).findViewById<View>(com.google.android.material.R.id.design_bottom_sheet) as FrameLayout?
            val behavior = BottomSheetBehavior.from(bottomSheet!!)
            behavior.state = BottomSheetBehavior.STATE_EXPANDED

            behavior.setBottomSheetCallback(object : BottomSheetBehavior.BottomSheetCallback() {
                override fun onStateChanged(bottomSheet: View, newState: Int) {
                    if (newState == BottomSheetBehavior.STATE_DRAGGING) {
                        behavior.state = BottomSheetBehavior.STATE_EXPANDED
                    }
                }

                override fun onSlide(bottomSheet: View, slideOffset: Float) {}
            })
        }

        // Do something with your dialog like setContentView() or whatever
        return dialog
    }

    ...
}

Answer 4

只需添加 void PrintEntity(class Entity* e);

您可以在BottomshitDialogFragment中获取BottomshitBehaviour的对象。

bottomSheetBehavior.setHideable(false);

Answer 5

如果要停用BottomSheetDialog拖动，请尝试设置setCancelable(false)。

Answer 6

评分最高的答案包含样板代码，例如Field和try-catches。

因此，这是Kotlin中更好的版本：

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    return super.onCreateDialog(savedInstanceState).apply {
        setOnShowListener(::onShow)
    }
}

private fun onShow(dialogInterface: DialogInterface) {
    val dialog = dialogInterface as BottomSheetDialog
    val frameLayout =
        dialog.findViewById<FrameLayout>(com.google.android.material.R.id.design_bottom_sheet)
            ?: return

    BottomSheetBehavior.from(frameLayout).apply {
        addBottomSheetCallback(object : BottomSheetBehavior.BottomSheetCallback() {
            override fun onStateChanged(bottomSheet: View, newState: Int) {
                if (newState == BottomSheetBehavior.STATE_DRAGGING)
                    state = BottomSheetBehavior.STATE_EXPANDED
            }

            override fun onSlide(bottomSheet: View, slideOffset: Float) = Unit
        })
    }
}

在BottomSheetDialogFragment

中使用它

Answer 7

这是azizbekian's答案的Kotlin版本，因为有人问有关使用数据绑定的问题

mydictofdict[1].update({'mykey1':'myval1'})

Answer 8

这是我设法解决的方法：

df['i']

Answer 9

我得到了答案here，我刚刚添加了pacakge.json，使“底页对话框”的片段高度为match_parent，并在显示时变软。

content.setLayoutParams(new CoordinatorLayout.LayoutParams(CoordinatorLayout.LayoutParams.MATCH_PARENT, CoordinatorLayout.LayoutParams.MATCH_PARENT));

Answer 10

简单的解决方案

    CoordinatorLayout.Behavior<View> behavior;

    View profile_config_layout_bottom_sheet = findViewById(R.id.list_view_audience_profile_config_layout);

    CoordinatorLayout.LayoutParams layoutParams = (CoordinatorLayout.LayoutParams) profile_config_layout_bottom_sheet.getLayoutParams();
    behavior = layoutParams.getBehavior();
    assert behavior != null;
    ((BottomSheetBehavior<View>) behavior).addBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
        @Override
        public void onStateChanged(@NonNull View bottomSheet, int newState) {
            if (newState == BottomSheetBehavior.STATE_DRAGGING) {
                ((BottomSheetBehavior<View>) behavior).setState(BottomSheetBehavior.STATE_EXPANDED);
            } 
        }
        @Override
        public void onSlide(@NonNull View bottomSheet, float slideOffset) {}
    });

Answer 11

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
    //Disable dragging by set isDraggable to false
    val bottomSheetDialog = dialog as BottomSheetDialog
    val bottomSheetBehavior = bottomSheetDialog.behavior
    bottomSheetBehavior.isDraggable = false
}

Answer 12

这是我的解决方案：

setOnShowListener {
            Handler().post {
                val bottomSheet = findViewById<View>(R.id.design_bottom_sheet) as? FrameLayout
                bottomSheet?.let {
                    BottomSheetBehavior.from(it).state = STATE_EXPANDED

                    // Disable dialog dragging behavior which causes issue on EditText scroll!
                    BottomSheetBehavior.from(it).isDraggable = false
                }

            }
        }

Answer 13

先生，这对我有用

override fun onCreateDialog(savedInstanceState : Bundle?) : Dialog {
    val dialog = super.onCreateDialog(savedInstanceState);
    dialog.setOnShowListener {
        val bottomSheetDialog : BottomSheetDialog = it as BottomSheetDialog;
        var bottomSheetBehavior = BottomSheetBehavior<FrameLayout>();
        bottomSheetBehavior = bottomSheetDialog.getBehavior()
        bottomSheetBehavior.setDraggable(false);
    }
    return dialog }

Answer 14

我的简单解决方案：

 override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    val dialog = BottomSheetDialog(requireContext(), R.style.DialogRoundedCornerStyle)
    dialog.behavior.apply {
        state = BottomSheetBehavior.STATE_EXPANDED
        isDraggable = false
    }
    return dialog
}

Answer 15

在您的oncreateView

//Kotlin
val baseDialog = dialog
if (baseDialog is BottomSheetDialog) {
    baseDialog.behavior.isDraggable = false
}
//If cancelable also not required.
isCancelable = false

Answer 16

他们也可以通过设置可拖动来做到这一点，所以这是我的另一个例子。

我的BottomSheetDialogFragment里面包含了一个RecyclerView，如果你需要一个BottomSheetDialogFragment禁止向上拖动，可以向下拖动，我做的是把RecyclerView设置为绝对高度

 <androidx.recyclerview.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="367dp"/>

Answer 17

为时已晚，但值得分享。

  behavior.setDraggable(false)

这行完成了工作。
