单击后如何禁用 RadioButton 的 Onclick？

Question

我正在创建一个测验应用程序，在其中提出问题并为用户提供选项。对于我使用 RadioButton 的选项所以我想要的是，一旦用户单击任何一个选项，它就不应该允许任何其他选项点击了，但问题是它仍然可以点击。如果可能，请写代码。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];

    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);

Answer 1

点击单选按钮后试试这个：

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

Answer 2

您可以使用setClickable(false);。为此：

yourradiobutton.setClickable(false);

Answer 3

如果我理解正确，您希望在单击某个 RadioButton 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，您无法重新启用 RadioGroup，除非您的代码中有其他逻辑可以重新启用。

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 it loops through each RadioButton 在检查 radio0 时：

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