我在开发由问题和多个单选按钮组成的应用程序的最后一部分，我知道如何将单选按钮的每个值分开，但现在我尝试插入单击选中的单选按钮的所有值按钮插入，但我有这个错误：java.lang.ILLegalStateException : could not find a method ajouter (View) in activity class。
请问你有什么想法吗？
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;

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

ajouter(v);

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