What I am trying to do: I am trying to make a custom dialog in android With rounded corners.

正在发生的事情:我可以创建自定义对话框，但它没有圆角.我尝试添加选择器，但仍然无法实现圆角.

What is happening: I am able to make custom dialog but it doesn't have rounded corners. I tried adding a selector but still I couldn't achieve rounded corners.

以下是我的相同代码:

Java代码:

private void launchDismissDlg() {

        dialog = new Dialog(getActivity(), android.R.style.Theme_Dialog);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.dlg_dismiss);
        dialog.setCanceledOnTouchOutside(true);

        Button btnReopenId = (Button) dialog.findViewById(R.id.btnReopenId);
        Button btnCancelId = (Button) dialog.findViewById(R.id.btnCancelId);

        btnReopenId.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {



            }
        });


        btnCancelId.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {



            }
        });
        dialog.setCanceledOnTouchOutside(false);
        dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
        dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
        dialog.show();

    }

xml代码:

<?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="match_parent"

                android:textColor="@android:color/black"
                android:textStyle="bold" />
        </TableRow>



        <TableRow

            android:layout_width="match_parent"
            android:layout_height="wrap_content" >

            <Button

            <Button

                android:padding="5dp"
                android:textSize="14sp"
                android:textColor="@android:color/white"
                android:textStyle="bold" />
        </TableRow>
    </TableLayout>

</LinearLayout>

推荐答案

在drawable中创建xml，例如dialog_bg.xml

Create a xml in drawable , say dialog_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid
        android:color="@color/white"/>
    <corners
        android:radius="30dp" />
    <padding
        android:left="10dp"
        android:top="10dp"
        android:right="10dp"
        android:bottom="10dp" />
</shape>

将其设置为布局xml中的背景

set it as the background in your layout xml

android:background="@drawable/dialog_bg"

将对话框的根视图的背景设置为透明，因为Android会将对话框布局放置在根视图中，该视图隐藏了自定义布局中的各个角.

Set the background of the dialog's root view to transparent, because Android puts your dialog layout within a root view that hides the corners in your custom layout.

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
