创建自定义样式,方法如下:
<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_corner_top_only</item>
</style>
然后在自定义片段中覆盖此方法。
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//bottom sheet round corners can be obtained but the while background appears to remove that we need to add this.
setStyle(DialogFragment.STYLE_NO_FRAME,R.style.AppBottomSheetDialogTheme);
}
这对我有效,希望对你也有用。
您需要更改底部弹出框主题
以实现顶部圆角布局
创建自定义可绘制的background_bottom_sheet_dialog_fragment.xml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="8dp"
android:topRightRadius="8dp" />
<padding android:top="0dp" />
<solid android:color="@color/white" />
</shape>
然后在styles.xml上使用drawable作为背景覆盖bottomSheetDialogTheme:
<!--Bottom sheet-->
<style name="BottomSheet" parent="@style/Widget.Design.BottomSheet.Modal">
<item
name="android:background">@drawable/background_bottom_sheet_dialog_fragment
</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" />
这将更改您底部工作表的背景布局
注意:从您的底部工作表对话框视图布局中删除所有背景
在你的BottomSheetDialogFragment中重写此方法
@Override
public void setupDialog(Dialog dialog, int style) {
View view = View.inflate(getContext(), R.layout.YOUR_LAYOUT, null);
dialog.setContentView(view);
((View) view.getParent()).setBackgroundColor(getResources().getColor(android.R.color.transparent));
}
BottomSheetDialogFragment
类的onStart()
方法中添加getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
