BottomSheetDialogFragment的圆角

我有一个自定义的bittomsheetdialogfragment，我想在底部视图的顶部有圆角

这是我的自定义类，它膨胀了我想要从底部显示的布局

View mView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    mView = inflater.inflate(R.layout.charge_layout, container, false);
    initChargeLayoutViews();
    return mView;
}

我还有这个XML资源文件作为背景:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
    <corners android:topRightRadius="35dp"
        android:topLeftRadius="35dp"
        />
    <solid android:color="@color/white"/>

    <padding android:top="10dp"
        android:bottom="10dp"
        android:right="16dp"
        android:left="16dp"/>
</shape>

问题是，当我把这个资源文件设置为我的布局的根元素的背景，角仍然不是圆角。

我不能使用以下代码:

this.getDialog().getWindow().setBackgroundDrawableResource(R.drawable.charge_layout_background);

因为它覆盖了底部对话框的默认背景，底部视图上方不会有任何半透明的灰色。

修复此问题的另一种方法是扩展BottomSheetDialog并创建适合您需要的自定义类。您可以为布局xml文件做同样的事情，并添加背景或任何其他所需的自定义。这也有一个好处，你将不依赖于Android使用的id名称(Android .support.design. r.id .design_bottom_sheet)，而改变背景(尽管id名称的变化很少发生AFAIK)。

创建一个名为rounded_corners_shape的形状

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
    <corners
        android:topLeftRadius="8dp"
        android:topRightRadius="8dp"/>
    <solid android:color="@color/white"/>

</shape>

定义一个样式

  <style name="AppBottomSheetDialogTheme"
           parent="Theme.Design.Light.BottomSheetDialog">
        <item name="bottomSheetStyle">@style/AppModalStyle</item>
    </style>

    <style name="AppModalStyle" parent="Widget.Design.BottomSheet.Modal">
        <item name="android:background">@drawable/rounded_corners_shape</item>
    </style>

在你的自定义BottomSheetDialogFragment上使用这种风格，它会工作的!

 public class CustomDialogFragment extends BottomSheetDialogFragment {
      @Override
      public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(STYLE_NORMAL, R.style. AppBottomSheetDialogTheme);
      }

      ...
    }

完整的解决方案:

将下面的样式属性添加到style.xml。

<style name="AppBottomSheetDialogTheme"
    parent="Theme.Design.Light.BottomSheetDialog">
    <item name="bottomSheetStyle">@style/AppModalStyle</item>
</style>

<style name="AppModalStyle"
    parent="Widget.Design.BottomSheet.Modal">
    <item name="android:background">@drawable/bottom_sheet_background</item>
</style>

然后使用AppBottomSheetDialogTheme从您的代码创建一个底部表对话框。

private fun openBottomSheetTermsCondition() {
    val mBottomSheetDialog = BottomSheetDialog(requireContext(),R.style.AppBottomSheetDialogTheme)
    val sheetView = layoutInflater.inflate(R.layout.bottom_sheet_travel_advice_terms, null)
    mBottomSheetDialog.setContentView(sheetView)
    sheetView.tv_head.setOnClickListener {
        mBottomSheetDialog.dismiss()
    }

    sheetView.webView.loadDataWithBaseURL(null,getString(R.string.privacy_policy_body_html),"text/html", "utf-8", null)
    mBottomSheetDialog.show()
}

我使用下面的绘图来圆底稿背景。

    <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners
        android:topLeftRadius="@dimen/bottom_sheet_corner_radius"
        android:topRightRadius="@dimen/bottom_sheet_corner_radius" />
    <solid android:color="@color/white" />
</shape>

底页对话框具有弯曲的形状和偷看高度

    <!-- BottomSheet Dialog -->
<style name="BottomSheetDialog" parent="Theme.Design.Light.BottomSheetDialog">
    <item name="bottomSheetStyle">@style/CustomBottomSheet</item>

</style>


<style name="CustomBottomSheet" parent="Widget.MaterialComponents.BottomSheet">
    <item name="shapeAppearanceOverlay">@style/CustomShapeAppearanceBottomSheetDialog</item>
    <item name="behavior_peekHeight">420dp</item>
</style>

<style name="CustomShapeAppearanceBottomSheetDialog" parent="">

我找到了一个简单的解决办法。 使用com.google.android.material:material:1.6.1

class MyBottomSheet: BottomSheetDialogFragment() {
    
      override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
            super.onViewCreated(view, savedInstanceState)
            disableShapeAnimation()
        }
    
      @SuppressLint("RestrictedApi", "VisibleForTests")
      private fun disableShapeAnimation() {
            try {
                val dlg = dialog as BottomSheetDialog
                dlg.behavior.disableShapeAnimations()
            } catch (ex: Exception) {
                Log.e("BaseBottomSheet", "disableShapeAnimation Exception:", ex)
            }
        }
}

简单的解决方案:

class TopRoundedCornersFragment : BottomSheetDialogFragment() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        setStyle(STYLE_NORMAL, R.style.AppBottomSheetDialogTheme)
    }
}

在styles.xml

<style name="BottomSheetStyle" parent="Widget.Design.BottomSheet.Modal">
    <item name="android:background">@drawable/bottom_sheet_dialog_bg</item>
</style>

<style name="AppBottomSheetDialogTheme" parent="Theme.Design.Light.BottomSheetDialog">
    <item name="bottomSheetStyle">@style/BottomSheetStyle</item>
</style>

最后，创建一个顶部圆角可绘制资源(bottom_sheet_dialog_bg.xml)

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <solid android:color="@android:color/white" />
    <corners
        android:topLeftRadius="4dp"
        android:topRightRadius="4dp" />

</shape>
