android - 向 BottomSheetDialogFragment 添加边距

Question

我尝试向我的 BottomSheetDialogFragment 添加边距，但它对边距没有任何作用。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_margin="16dp">

    <TextView
        android:id="@+id/alertdialog_fragmail_newmessage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Test 1"
        android:textStyle="bold"
        android:padding="16dp"
        android:textColor="@color/colorBlackFont"
        android:layout_alignParentTop="true"
        android:gravity="center_vertical"
        android:drawablePadding="16dp"/>


  //More Textviews

</RelativeLayout>

我已经尝试将 XML 更改为下面的答案，但是它仍然没有为我的 bottomsheetdialogfragment 创建边距。

底部工作表对话框 fragment 类的代码:

public class FragMailMoreDialog extends BottomSheetDialogFragment {

    private static final String TAG = "FragMailMoreDialog";

    private Context mContext;


    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mContext = getContext();
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater,
                             @Nullable ViewGroup container,
                             @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.alertdialog_layout_fragmailmore, container, false);
        ButterKnife.bind(this, view);


        return view;
    }
}

充气底片的代码:

private void inflateMoreDialog(){
        FragMailMoreDialog moreDialog = new FragMailMoreDialog();
        if (getFragmentManager() != null) {
            moreDialog.show(getFragmentManager(), "FRAGMAIL_MORE_DIALOG");
        }
    }

有点hacky的解决方案:

我将布局包裹在另一个 RelativeLayout 中，并使该布局的背景透明。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="@android:color/transparent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorWhite"
        android:layout_margin="16dp">

    <TextView
        android:id="@+id/alertdialog_fragmail_newmessage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Test 1"
        android:textStyle="bold"
        android:padding="16dp"
        android:textColor="@color/colorBlackFont"
        android:layout_alignParentTop="true"
        android:gravity="center_vertical"
        android:drawablePadding="16dp"
        android:background="?attr/selectableItemBackground"/>
    </RelativeLayout>
</RelativeLayout>

在 BottomSheetDialogFragment 中，您需要覆盖 setupDialog

@Override
    public void setupDialog(Dialog dialog, int style) {
        View contentView = View.inflate(getContext(), R.layout.alertdialog_layout_fragmailmore, null);
        dialog.setContentView(contentView);
        ((View) contentView.getParent()).setBackgroundColor(getResources().getColor(android.R.color.transparent));
    }
