public class RadioDialog implements View.OnClickListener {
    Dialog mRadioDialog;
    private TextView mBtnOk;
    private TextView mBtnCancel;
    private View.OnClickListener okOnClickListener;
    private View.OnClickListener cancelOnClickListener;
    String item;//选择的选项值
    public void setOkOnClickListener(View.OnClickListener okOnClickListener) {
        this.okOnClickListener = okOnClickListener;
    }

    public void setCancelOnClickListener(View.OnClickListener cancelOnClickListener) {
        this.cancelOnClickListener = cancelOnClickListener;
    }
    public String getItem() {
      return item;
    }
    public RadioDialog(Activity context, String prompt,
                       String okName, String caName) {
        // 首先得到整个View
        View view = LayoutInflater.from(context).inflate(
                R.layout.radio_dialog, null);
        // 页面中显示文本
        TextView mPrompt =  view.findViewById(R.id.text_title);
        //单选组
        RadioGroup radioGroup=view.findViewById(R.id.radio_dialog_radiogroup);
        radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup radioGroup, int i) {
                //获取选择的选项，取值
                RadioButton rb = view.findViewById(radioGroup.getCheckedRadioButtonId());
                item=rb.getText().toString();
            }
        });
        mBtnOk =  view.findViewById(R.id.button_ok);
        mBtnCancel =  view.findViewById(R.id.button_cancel);
        // 显示文本
        mPrompt.setText(prompt);
        mBtnOk.setText(okName);
        mBtnCancel.setText(caName);
        mBtnOk.setOnClickListener(this);
        mBtnCancel.setOnClickListener(this);
        // 创建自定义样式的Dialog
        mRadioDialog = new Dialog(context, R.style.loading_dialog);
        int w = context.getWindowManager().getDefaultDisplay().getWidth();
        view.setMinimumWidth(w * 4 / 5);//设置dialog的宽度
        // 设置返回键无效
        mRadioDialog.setCancelable(false);        mRadioDialog.setContentView(view, new ActionBar.LayoutParams(//设置dialog
                android.view.ViewGroup.LayoutParams.WRAP_CONTENT,
                android.view.ViewGroup.LayoutParams.WRAP_CONTENT));
    }

    public void show() {
        if (!mRadioDialog.isShowing()){
            mRadioDialog.show();
        }
    }

    public void close() {
        if (mRadioDialog != null) {
            mRadioDialog.dismiss();
            mRadioDialog = null;
        }
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.button_cancel:
                if (cancelOnClickListener != null) {
                    cancelOnClickListener.onClick(view);
                }
                break;
            default:
                if (okOnClickListener != null) {
                    okOnClickListener.onClick(view);
                }
                break;
        }
    }
}

二、自定义的Dialgo的style

<style name="loading_dialog" parent="android:style/Theme.Dialog">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:windowContentOverlay">@null</item>
</style>

三、布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    style="@android:style/Theme.Dialog"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/newfolder_dilaog_back"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            android:id="@+id/text_title"
            android:layout_width="match_parent"
            android:layout_height="@dimen/title_tab"
            android:gravity="center"
            android:text="送达结果"
            android:textColor="@color/text_color"
            android:textSize="@dimen/content_text" />
        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="16dp">

            <TextView
                android:layout_width="match_parent"
                android:layout_height="@dimen/lines_weight_2px"
                android:background="@color/activity_background" />
        </FrameLayout>

        <RadioGroup
            android:id="@+id/radio_dialog_radiogroup"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:orientation="vertical"
            android:paddingLeft="@dimen/height_30dp"
            android:paddingRight="@dimen/height_30dp">

            <RadioButton
                android:layout_width="200dp"
                android:layout_height="match_parent"
                android:layout_gravity="center"
                android:layout_marginBottom="8dp"
                android:background="@drawable/radiobutton_select_backgroud"
                android:button="@null"
                android:gravity="center"
                android:padding="4dp"
                android:text="完成"
                android:textColor="@color/radiobutton_text_select_backgroud"
                android:textSize="@dimen/textsize15" />

            <RadioButton
                android:layout_width="200dp"
                android:layout_height="match_parent"
                android:layout_gravity="center"
                android:layout_marginBottom="8dp"
                android:background="@drawable/radiobutton_select_backgroud"
                android:button="@null"
                android:gravity="center"
                android:padding="4dp"
                android:text="拒收"
                android:textColor="@color/radiobutton_text_select_backgroud"
                android:textSize="@dimen/textsize15" />

            <RadioButton
                android:layout_width="200dp"
                android:layout_height="match_parent"
                android:layout_gravity="center"
                android:layout_marginBottom="8dp"
                android:background="@drawable/radiobutton_select_backgroud"
                android:button="@null"
                android:gravity="center"
                android:padding="4dp"
                android:text="留置"
                android:textColor="@color/radiobutton_text_select_backgroud"
                android:textSize="@dimen/textsize15" />

            <RadioButton
                android:layout_width="200dp"
                android:layout_height="match_parent"
                android:layout_gravity="center"
                android:layout_marginBottom="16dp"
                android:background="@drawable/radiobutton_select_backgroud"
                android:button="@null"
                android:gravity="center"
                android:padding="4dp"
                android:text="其他"
                android:textColor="@color/radiobutton_text_select_backgroud"
                android:textSize="@dimen/textsize15" />

        </RadioGroup>
    </LinearLayout>

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

        <TextView
            android:layout_width="match_parent"
            android:layout_height="@dimen/lines_weight_2px"
            android:background="@color/text_color" />
    </FrameLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/button_cancel"
            android:layout_width="0dp"
            android:layout_height="@dimen/title_tab"
            android:layout_weight="1"
            android:background="@drawable/button_cancel_selector_back"
            android:gravity="center"
            android:padding="10dp"
            android:text="取消"
            android:textColor="@color/colorPrimary"
            android:textSize="@dimen/content_text" />

        <FrameLayout
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_marginBottom="2dp"
            android:layout_marginTop="2dp">

            <TextView
                android:layout_width="@dimen/lines_weight_2px"
                android:layout_height="match_parent"
                android:background="@color/text_color" />
        </FrameLayout>

        <TextView
            android:id="@+id/button_ok"
            android:layout_width="0dp"
            android:layout_height="@dimen/title_tab"
            android:layout_weight="1"
            android:background="@drawable/button_ok_selector_back"
            android:gravity="center"
            android:padding="10dp"
            android:text="确定"
            android:textColor="@color/colorPrimary"
            android:textSize="@dimen/content_text" />
    </LinearLayout>

</LinearLayout>

四、单选按钮的background

再drawable下创建新的xml文件

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/radiobutton_background_unchecked" android:state_checked="false" />
    <item android:drawable="@drawable/radiobutton_background_checked" android:state_checked="true" />
</selector>

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <!-- 填充 -->
    <solid android:color="@color/colorPrimary" />
    <!-- 圆角 -->
    <corners android:radius="24dp" />
</shape>

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <!-- 填充 -->
    <solid android:color="@color/activity_background" />
    <!-- 圆角 -->
    <corners android:radius="24dp" />
</shape>

五、单选按钮文字颜色

再res创建color文件夹，新建xml文件
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/text_color"
        android:state_checked="false" />
    <item android:color="@color/text_color_white"
        android:state_checked="true" />
</selector>

六、java代码中使用

RadioDialog radioDialog=new RadioDialog(this,"送达结果","确定","取消");
radioDialog.show();
radioDialog.setCancelOnClickListener(v -> radioDialog.close());
radioDialog.setOkOnClickListener(v -> {
    String item=radioDialog.getItem();
    Toast.makeText(context,item,Toast.LENGTH_SHORT).show();
    radioDialog.close();
});
