Question

我有Fragment，显示Dialog。在Dialog内，有一个RadioGroup。我试图为这个RadioGroup创建一个听众，但我没有成功。

Fragment - ＆gt; Dialog - ＆gt; RadioGroup

我尝试了四种方式：

OnCheckedChangeListener

RadioGroup。

OnClickListener

RadioGroup

OnCheckedChangeListener

RadioButton

OnClickListener RadioButton

没有人工作。

这是我的代码：

Dialog - 布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical">


    <RadioGroup
        android:id="@+id/bS_rg"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:orientation="vertical">

        <RadioButton
            android:id="@+id/r_id"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:text="ID"
            android:textSize="24sp" />

        <RadioButton
            android:id="@+id/r_title"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:text="Title"
            android:textSize="24sp" />

        <RadioButton
            android:id="@+id/r_genre"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:text="Genre"
            android:textSize="24sp" />

        <RadioButton
            android:id="@+id/r_author"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:text="Author"
            android:textSize="24sp" />

    </RadioGroup>

    <AutoCompleteTextView
        android:id="@+id/c_bSearch"
        android:layout_width="278dp"
        android:layout_height="72dp"
        android:singleLine="true"/>

</LinearLayout>

Fragment - 布局：

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

    <de.codecrafters.tableview.TableView
        android:id="@+id/tableView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

和Fragment - 代码:(我标记的问题在哪里，其他代码并不重要）

package com.example.adiel.library_app_30;

import .....;

public class ShowAllBooks extends Fragment {
    View v;
    TableLayout table;
    TableRow row;
    String[] spaceProbeHeaders = {"ID", "Title"};
    String[][] spaceProbes;
    AutoCompleteTextView c_search;


    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
        v = inflater.inflate(R.layout.show_all_books, container, false);
        setHasOptionsMenu(true);

        /*
        ------The problem is here----
        */
        LayoutInflater li = LayoutInflater.from(v.getContext());
        View promptsView = li.inflate(R.layout.b_search_dialog, null);
        c_search = (AutoCompleteTextView) promptsView.findViewById(R.id.c_bSearch);
        RadioGroup rg = (RadioGroup) promptsView.findViewById(R.id.bS_rg);
        rg.check(R.id.r_id);

        rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId)
            {
                Log.d("Log", "Clicked");
            }
        });

        rg.setOnClickListener(new View.OnClickListener() {

                    tb.setDataAdapter(new SimpleTableDataAdapter(v.getContext(), spaceProbes));
