Java 按单选按钮后通过文本视图显示字符串中的文本

我试图在按下单选按钮后自动显示“这是正确答案”或“再试一次”

我的问题是：

如何添加两个字符串

    <string name="Good_answer">That is the correct answer</string>
<string name="Wrong_answer">Try again</string>

这是setOnClick。。。（一开始是用“mbuton”复选按钮）

Xml

和字符串

   <string name="Good_answer">That is the correct answer</string>
<string name="Wrong_answer">Try again</string>

这是正确的答案
再试一次

如果您的问题只是在TextView中设置这些字符串，请尝试以下操作：

//For correct answer.
String CorrectAnswer = getString(R.string.Good_answer);
tv.setText(CorrectAnswer);

//For wrong answer.
String WrongAnswer = getString(R.string.Wrong_answer);
tv.setText(WrongAnswer);

代码仍然不清楚（我不知道mButton是什么）。 但是，您也可以共享您的布局xml吗？我建议您创建一个由X个您喜欢的单选按钮（选项）组成的单选组，并将其置于checkedChangeListener上

<RadioGroup
    android:id="@+id/rgroup"
    android:layout_width="fill_parent"
    android:layout_height="45dp"
    android:background="@drawable/background"
    android:gravity="center"
    android:orientation="horizontal" >

    <RadioButton
        android:id="@+id/option1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:background="@drawable/test_image"
        android:button="@null" />

 <RadioButton
        android:id="@+id/option2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dp"
        android:background="@drawable/test_image"
        android:button="@null" />


</RadioGroup>

}

---

假设您可能在动态位置有答案，您可能希望在on checked change方法中编写一些逻辑。希望这对布局文件有帮助；看看这些问题和答案。我已经在这里硬编码了字符串。您可以在字符串资源文件中设置它，并使用

@string

在此处获取它，或者使用

yourTextView.setText（）方法动态设置它
