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。
在你的BottomsheetDialogFragment类中添加这两个方法。
public void setDialogBorder(Dialog dialog) {
FrameLayout bottomSheet = (FrameLayout) dialog.getWindow().findViewById(android.support.design.R.id.design_bottom_sheet);
bottomSheet.setBackground(new ColorDrawable(Color.TRANSPARENT));
setMargins(bottomSheet, 10, 0, 10, 20);
}
private void setMargins(View view, int left, int top, int right, int bottom) {
if (view.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
p.setMargins(left, top, right, bottom);
view.requestLayout();
}
}
现在调用你的BottomsheetDialogFragment类的setupDialog()方法中的setDialogBorder(dialog)方法。
现在在可绘制文件夹中创建一个形状文件。
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="20dp" />
<solid android:color="@color/white" />
<stroke
android:width="1dp"
android:color="@color/transparent" />
</shape>
现在在xml文件中设置父视图组对话框视图的背景。
android:background="@drawable/round_border_white"
完成了! !

android:background="@drawable/round_border_white"
完成了! !
底部对话框设置了默认的白色背景色，这就是为什么角落是不可见的，为了显示它们，你需要通过覆盖底部对话框的风格使对话框的背景透明。
在res/values/styles/styles.xml中定义此样式
<style name="BottomSheetDialog" parent="Theme.Design.Light.BottomSheetDialog">
<item name="bottomSheetStyle">@style/bottomSheetStyleWrapper</item>
</style>
<style name="bottomSheetStyleWrapper" parent="Widget.Design.BottomSheet.Modal">
<item name="android:background">@android:color/transparent</item>
</style>
并将此样式设置为您的BottomSheetDialog
View view = getLayoutInflater().inflate(R.layout.chooser_bottom_sheet, null);
BottomSheetDialog dialog = new BottomSheetDialog(this,R.style.BottomSheetDialog); // Style here
dialog.setContentView(view);
dialog.show();
我今天也检查了同样的事情，是的，你是对的，下面的代码
this.getDialog().getWindow().setBackgroundDrawableResource(R.drawable.charge_layout_background);
这适用于片段背景，所以相反，你应该从对话框窗口获得底部表视图，并改变背景，这里是代码
@SuppressLint("RestrictedApi")
@Override
public void setupDialog(Dialog dialog, int style) {
super.setupDialog(dialog, style);
View rootView = getActivity().getLayoutInflater().inflate(R.layout.view_member_info,null,false);
unbinder = ButterKnife.bind(this, rootView);
adjustUIComponents();
dialog.setContentView(rootView);
FrameLayout bottomSheet = (FrameLayout) dialog.getWindow().findViewById(android.support.design.R.id.design_bottom_sheet);
bottomSheet.setBackgroundResource(R.drawable.container_background);
}
这里的底部是你想要改变的实际视图。
Create a shape drawable .. which we will use as background for bottom sheet .
Provide the appropriate value for radius of top left and right corner .
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:topLeftRadius="24dp"
android:topRightRadius="24dp" />
<padding android:top="2dp" />
<solid android:color="@color/white" />
</shape>
Now create style for " Bottom sheet dialog fragment "
<style name="BottomSheet" parent="@style/Widget.Design.BottomSheet.Modal">
<item name="android:background">@drawable/drawable_bottomsheet_background</item>
</style>
<style name="BaseBottomSheetDialog" parent="@style/Theme.Design.Light.BottomSheetDialog">
<item name="android:windowIsFloating">false</item>
<item name="bottomSheetStyle">@style/BottomSheet</item>
</style>
<style name="BottomSheetDialogTheme" parent="BaseBottomSheetDialog" />
Now create a custom class that will extend BottomSheetDilogFragment ,where you provide your style .
open class CustomRoundBottomSheet : BottomSheetDialogFragment() {
override fun getTheme(): Int = R.style.BottomSheetDialogTheme
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog = BottomSheetDialog(requireContext(), theme)
}
Now use this class wherever you want to have round corner bottom sheet .
eg
class BottomSheetSuccess : CustomRoundBottomSheet() {
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
return inflater.inflate(R.layout.bottomsheet_shopcreate_success, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
}
}
