Question

我在开发一个由问题和多个单选按钮组成的应用程序的最后一部分，我知道如何插入单选按钮的每个值，但现在我试图插入所选的单选按钮的所有值单击按钮插入，但我有这个错误：java.lang.ILLegalStateException : could not find a method ajouter (View) in activity class。

请你知道吗？

public class MainActivity extends Activity {

DBAdapter db = new DBAdapter(this); 
  int x=0;
  int y=0;
  int z=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

        db.open();

    //  RadioGroup  radio =(RadioGroup)findViewById(rm_25_1);
        RadioButton rad0 = (RadioButton) findViewById (R.id.rm_25_1_1);
        RadioButton rad1 = (RadioButton) findViewById (R.id.rm_25_1_2);

  //      RadioGroup  Télévision  =(RadioGroup)findViewById(rm_25_2);
        RadioButton tel0 = (RadioButton) findViewById (R.id.rm_25_2_1);
        RadioButton tel1 = (RadioButton) findViewById (R.id.rm_25_2_2);

//          RadioGroup  Réfrigérateur =(RadioGroup)findViewById(rm_25_3);
        RadioButton ref0 = (RadioButton) findViewById (R.id.rm_25_3_1);
        RadioButton ref1 = (RadioButton) findViewById (R.id.rm_25_3_2);

}

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_25_1_1:
                    if (checked)
                          x=0;
                          Toast.makeText(getApplicationContext(), "Données enregistrées!!! =)", Toast.LENGTH_LONG).show();
                        break;
                case R.id.rm_25_1_2:
                    if (checked)
                        x=1;
                          Toast.makeText(getApplicationContext(), "Données enregistrées!!! =)", Toast.LENGTH_LONG).show();
                        break;
                case R.id.rm_25_2_1:
                    if (checked)
                        y=0;
                          Toast.makeText(getApplicationContext(), "Données enregistrées!!! =)", Toast.LENGTH_LONG).show();
                        break;
                case R.id.rm_25_2_2:
                    if (checked)
                        y=1;
                          Toast.makeText(getApplicationContext(), "Données enregistrées!!! =)", Toast.LENGTH_LONG).show();
                        break;
                case R.id.rm_25_3_1:
                    if (checked)
                        z=0;
                          Toast.makeText(getApplicationContext(), "Données enregistrées!!! =)", Toast.LENGTH_LONG).show();
                        break;
                case R.id.rm_25_3_2:
                    if (checked)
                        z=1;
                          Toast.makeText(getApplicationContext(), "Données enregistrées!!! =)", Toast.LENGTH_LONG).show();

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


          @Override
          public void onClick(View v) {

                ajouter(v);
                Toast.makeText(getApplicationContext(), "Données enregistrées!!! =)", Toast.LENGTH_LONG).show();

          }

          public void  ajouter(View v) {
               db.insertcc(x,y,z);

          }
        });

  }}

Answer 1

尝试将ajouter(v);来电更改为this.ajouter(v);。 this应该引用您的OnClickListener类。

Answer 2

将您的ajouter（）方法从click侦听器类中取出，并将其作为您活动的私有成员。

只需单击一下即可插入多个值单选按钮
