在简历上有单选按钮的值

我有resume方法中存储的单选按钮的值,但是当我尝试注册值时,我有NO VALUE IS DETECTED。奇怪的是,我看到选中了单选按钮,但值为零。 所以,当我去数据库时,我有一个= 0和b = 0,这意味着没有点击单选按钮, 当我再次单击单选按钮,然后按下按钮,我在数据库中有正确的值,我正在寻找的是我不必再单击单选按钮。

    public class ActivityUn extends Activity {
        public void  ajouter(View v) {

      db.open();               
          db.insertMENAGE(a,b);                   
          db.close();
          Toast.makeText(getApplicationContext(), "Données Enregistrées",            Toast.LENGTH_SHORT).show();
              } 


   @Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_un);       

         Button bton = (Button)findViewById(R.id.ajoutUn);
         bton.setOnClickListener(new View.OnClickListener() {  

          @Override
             public void onClick(View v) {

                   ajouter(v);                                            }
         });

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.rm_13_1:
                    if (checked)
                          a=1;
                        break;
                case R.id.rm_13_2:
                    if (checked)
                        a=2;
                        break;

                case R.id.rm_14_1:
                    if (checked)
                        b=1;

                    break;
                case R.id.rm_14_2:
                    if (checked)
                        b=2;
                       break;
                case R.id.rm_14_3:
                    if (checked)
                        b=3;
                    findViewById
                    break;
                case R.id.rm_14_4:
                    if (checked)
                        b=4;
                          break;
  }
}




@Override

@Override

    super.onResume();
    SharedPreferences prefs3 = getSharedPreferences(PREFS_NAME,
        MODE_PRIVATE);
    rm_13_1 = (RadioButton) findViewById(R.id.rm_13_1);

我在你的代码中看到两个错误。

首先你的XML中有rm_14_4,但我从未在你的代码中看到过初始化。

第二个波纹管代码指的是一个按钮,请修复:

rm_14_2 = (RadioButton) findViewById(R.id.rm_14_2);
rm_14_3 = (RadioButton) findViewById(R.id.rm_14_2);

你使用了RadioGroup,所以使用:

int radioButtonID = radioButtonGroup.getCheckedRadioButtonId();

有关详细信息,请参阅this

使用RadioGroup.getCheckedRadioButtonId()RadioGroup.check()而不是在单个单选按钮上调用RadioButton.isChecked()RadioButton.setChecked()。使用RadioGroup.setOnCheckedChangeListener()(通过代码,而不是xml布局)来收听RadioGroup中的更改。
