SqlLiteExample.java：

public class SqlLiteExample extends Activity implements OnClickListener, OnCheckedChangeListener {
Button sqlUpdate, sqlView;
EditText etName,etAge,etContact;
RadioGroup rdgrp;
RadioButton selectedRadioButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.sqlliteexample);
    sqlUpdate = (Button) findViewById(R.id.savebutton);
    etName = (EditText) findViewById(R.id.editName);
    etAge = (EditText) findViewById(R.id.editAge);
    etContact = (EditText) findViewById(R.id.editContact);
    rdgrp.setOnCheckedChangeListener(this);

    sqlView = (Button) findViewById(R.id.viewbutton);
    sqlView.setOnClickListener(this);
    sqlUpdate.setOnClickListener(this);

}

@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub
    switch(arg0.getId()){
    case R.id.savebutton:
        boolean didWork = true;
        try{
        String name = etName.getText().toString();
        String age = etAge.getText().toString();
        String contact = etContact.getText().toString();

        MyDB entry = new MyDB(SqlLiteExample.this);
        entry.open();
        entry.createEntry(name,age,contact);
        entry.close();
        }catch(Exception e){
            didWork = false;
            String error = e.toString();
            Dialog d = new Dialog(this);
            d.setTitle("Error");
            TextView tv = new TextView(this);
            tv.setText(error);
            d.setContentView(tv);
            d.show();
        }finally{
            if(didWork){
                Dialog d = new Dialog(this);
                d.setTitle("Updated");
                TextView tv = new TextView(this);
                tv.setText("Success");
                d.setContentView(tv);
                d.show();
            }

        }
        break;
    case R.id.viewbutton:
        Intent i = new Intent("com.bysakiralam.mydatabase.DISPLAYRECORDS");
        startActivity(i);
        break;
    }
}

@Override
public void onCheckedChanged(RadioGroup arg0, int arg1) {
    // TODO Auto-generated method stub
    switch(arg1){
    case R.id.malebutton:
        break;
    case R.id.femalebutton:
        break;
    }
} }

Answer 1

无需覆盖onCheckedChanged（）使用以下保存按钮单击

rdgrp=(RadioGroup)findViewById(R.id.RadioGroup01);
 String radiovalue=  (RadioButton)this.findViewById(rdgrp.getCheckedRadioButtonId())).getText().toString();

现在使用radiovalue存储在数据库中

编辑：忘记了（

rdgrp=(RadioGroup)findViewById(R.id.RadioGroup01);
 String radiovalue=  ((RadioButton)this.findViewById(rdgrp.getCheckedRadioButtonId())).getText().toString();

Answer 2

试试这个

myRadioGrp=(RadioGroup)findViewById(R.id.RadioGroup01);
 String radiovalue= ((RadioButton)this.findViewById(myRadioGrp.getCheckedRadioButtonId())).getText().toString();

如何在sqlite数据库中存储radiogroup的文本值？
