單選按鈕找不到單擊方法

Question

我的單選按鈕不會找到onRadioButtonClicked單擊的方法。該方法說，它從來沒有使用過，當我嘗試radioButton應用程序崩潰，因爲沒有onRadioButtonClicked方法。

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

      <RadioButton 
       android:id="@+id/rbTerrorist" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:onClick="onRadioButtonClicked" 
       android:text="Terrorist" /> 

      <RadioButton 
       android:id="@+id/rbCounterTerrorist" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:onClick="onRadioButtonClicked" 
       android:text="Counter-Terrorist" /> 
     </RadioGroup> 

public void onRadioButtonClicked(View view) { 
     // Is the button now checked? 
     boolean checked = ((RadioButton) view).isChecked(); 

     // Check which radio button was clicked 
     switch (view.getId()) { 
      case R.id.rbTerrorist: 
       if (checked) 
        // Pirates are the best 
        break; 
      case R.id.rbCounterTerrorist: 
       if (checked) 
        // Ninjas rule 
        break; 
      default: 
       break; 
     } 
    }

你應該使用RadioButton叫什麼和RadioGroup是OnCheckedChangeListener

使用這種方法

RadioGroup rb = (RadioGroup) findViewById(R.id.your_Radio_group_id); 
    rb.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
     public void onCheckedChanged(RadioGroup group, int checkedId) { 
      switch (checkedId) { 
       case R.id.rbTerrorist: 
        // to task           
        break; 
       case R.id.rbCounterTerrorist: 
        // to task           
        break; 
      } 
     } 

    });
