我一直试图只保留其中一个单选按钮，但每次用户都可以选择多个单选按钮。
如何只保留一个或当前选中的单选按钮？
我基本上有一个TableLayout，它有一个TableRow作为XML布局，从代码中发挥作用。此外，在RadioButton上应用了onClickListener，它为当前选定的单选按钮提取tag。
有人可以帮我解决这个问题吗？
对于参考。我的Table Row的XML布局：
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tblDynStoreRow"
android:layout_margin="0.0dp"
android:layout_width="match_parent" >
<TextView
android:id="@+id/tvStoreCount"
android:textSize="10sp"
android:layout_width="wrap_content"
android:layout_height="12dp"
android:singleLine="true"
android:scrollHorizontally="true" />
<RadioButton
android:id="@+id/rb1StoreName"
android:textSize="10sp"
android:layout_width="wrap_content"
android:layout_height="31dp"
android:singleLine="true"
android:scrollHorizontally="true" />
</TableRow>
onCreate（）方法：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_store_selection);
TableLayout tl = (TableLayout) findViewById(R.id.mainstoretable);
//RadioButton rb1;

// UsrGPSLock = i.getStringExtra("currUsrLat") + "," +

为了防止多次检查RadioButton，它们必须都在同一个RadioGroup中。
要么在XML中定义一个Radiogroup（但是从我看到你试图做的那个将是困难的）
或者您使用Java创建它：RadioGroup rg = new RadioGroup(this);

试试这个......希望它有效
RadioGroup rg = new RadioGroup(this);
RadioButton[] rb = new RadioButton[storeList.length];
for (int current = 0; current <= (storeList.length - 1); current++) {
TableRow storeRow = (TableRow)inflater.inflate(R.layout.store_table_row, tl, false);
TextView tv1 = (TextView)storeRow.findViewById(R.id.tvStoreCount);
rb[current] = (RadioButton)storeRow.findViewById(R.id.rb1StoreName);
rg.addView(rb[current]);
