Java 如何在单击单选按钮后禁用单选按钮的Onclick？

我正在创建一个测验应用程序，其中有一个问题，并为用户提供选项。对于选项，我使用了RadioButton，因此我想要的是，一旦用户单击任何一个选项，它不应允许单击任何其他选项，但问题是它仍然可以单击。如果可能，请编写代码。谢谢

private int Question_no=0;
private Boolean Boolean_Var=false;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_question1);

    String[] Question_Array = getResources().getStringArray(R.array.Question1);
    TextView Questions = (TextView) findViewById(R.id.Question);
    Questions.setText(Question_Array[Question_no]);

    String[] Radio_Button1_Array = getResources().getStringArray(R.array.Option_1);
    RadioButton Radio_Button1 = (RadioButton) findViewById(R.id.radioButton1);
    Radio_Button1.setText(Radio_Button1_Array[Question_no]);

    String[] Radio_Button2_Array = getResources().getStringArray(R.array.Option_2);
    RadioButton Radio_Button2 = (RadioButton) findViewById(R.id.radioButton2);
    Radio_Button2.setText(Radio_Button2_Array[Question_no]);

    findViewById(R.id.MenuButton).setVisibility(View.INVISIBLE);
    findViewById(R.id.NextButton).setVisibility(View.INVISIBLE);
}

public void On_RadioButton1_Click (View view)
{
    if (Boolean_Var == false) {
        String[] CorrectAns_Array = getResources().getStringArray(R.array.Answer1);
        String CorrectAns = CorrectAns_Array[Question_no];
        String[] Answer_Array = getResources().getStringArray(R.array.Option_1);
        String Answer = Answer_Array[Question_no];


        if (Answer.equals(CorrectAns)) {
            RadioButton Right_Ans = (RadioButton) findViewById(R.id.radioButton1);
            Right_Ans.setTextColor(Color.GREEN);
            AnswerSubmitted();
        } else {
            RadioButton Wrong_Ans = (RadioButton) findViewById(R.id.radioButton1);
            Wrong_Ans.setTextColor(Color.RED);;
            GreenTick();
            AnswerSubmitted();
        }
    }
    Boolean_Var = true;

}

public void On_RadioButton2_Click(View view)
{
    if(Boolean_Var==false)
    {
        String[] CorrectAns_Array = getResources().getStringArray(R.array.Answer1);
        String CorrectAns = CorrectAns_Array[Question_no];
        String[] Answer_Array = getResources().getStringArray(R.array.Option_2);
        String Answer = Answer_Array[Question_no];


        if(Answer.equals(CorrectAns))
        {
            RadioButton Right_Ans = (RadioButton) findViewById(R.id.radioButton2);
            Right_Ans.setTextColor(Color.GREEN);
        }
        else
        {
            RadioButton Wrong_Ans = (RadioButton) findViewById(R.id.radioButton2);
            Wrong_Ans.setTextColor(Color.RED);
            GreenTick();
        }
    }
    Boolean_Var=true;
    AnswerSubmitted();
}

 public void GreenTick()
{
    String[] Answer1_Array = getResources().getStringArray(R.array.Option_1);
    String Answer1 = Answer1_Array[Question_no];

    String[] Answer2_Array = getResources().getStringArray(R.array.Option_2);
    String Answer2 = Answer2_Array[Question_no];

    String[] Answer3_Array = getResources().getStringArray(R.array.Option_3);
    String Answer3 = Answer3_Array[Question_no];

    String[] The_CorrectAns_Array = getResources().getStringArray(R.array.Answer1);
    String The_CorrectAnsIs = The_CorrectAns_Array[Question_no];

    if(The_CorrectAnsIs.equals(Answer1))
    {
        Button Option_with_CorrectAns = (Button) findViewById(R.id.radioButton1);
        Option_with_CorrectAns.setTextColor(Color.GREEN);
    }
    else if(The_CorrectAnsIs.equals(Answer2))
    {
        Button Option_with_CorrectAns = (Button) findViewById(R.id.radioButton2);
        Option_with_CorrectAns.setTextColor(Color.GREEN);
    }
    else if(The_CorrectAnsIs.equals(Answer3))
    {
        Button Option_with_CorrectAns = (Button) findViewById(R.id.radioButton3);
        Option_with_CorrectAns.setTextColor(Color.GREEN);

    else
    {
        Button Option_with_CorrectAns = (Button) findViewById(R.id.radioButton4);
        Option_with_CorrectAns.setTextColor(Color.GREEN);

如果我理解正确，您希望在单击某个单选按钮后禁用RadioGroup。只需添加一个OnCheckedChangedListener，如果单击的RadioButton的id是正确的，则使用setEnabled（false）禁用该组。当然，除非代码中有其他逻辑来执行重新启用，否则无法重新启用RadioGroup

RadioGroup radioGroup = (RadioGroup)findViewById (R.id.radioGroup1);
radioGroup.setOnCheckedChangedListener (new OnCheckedChangedListener(){
public void onCheckedChanged(RadioGroup group, int checkedId) 
{
 if (checkedId == R.id.radio0)
group.setEnabled(false);
}
});

编辑：似乎setEnabled（）不起作用，因此您应该尝试更改代码，以便在检查radio0时使用RadioButton：

if (checkedId == R.id.radio0){
 for(int i = 0; i < group.getChildCount(); i++){
        ((RadioButton)rg1.getChildAt(i)).setEnabled(false);
    }
}

if（checkedId==R.id.0）{
对于（int i=0；i

您可以使用

setClickable（false）。为此：

yourradiobutton.setClickable(false);

单击radiobutton后尝试此操作：

   yourradiobutton.setClickable(false);
yourradiobutton.setClickable(false);

仅供参考，如果您将单选按钮设置为Enabled（false），它将变灰，并且不会显示为“checked”。它不仅禁用单击，而且禁用整个单选按钮（因此不再显示“选中”状态）
