radioGroup = (RadioGroup) findViewById(R.id.radioGroup1);
r0 = (RadioButton) findViewById(R.id.radio0);
r1 = (RadioButton) findViewById(R.id.radio1);
r2 = (RadioButton) findViewById(R.id.radio2);
r3 = (RadioButton) findViewById(R.id.radio3);
bsubmit = (Button) findViewById(R.id.bsubmit);
bsubmit.setOnClickListener(this);
String shoow = myDb.makeatext(levels, Qno);
String showextra1 = myDb.makeExtra1(levels, Qno);
String showextra2 = myDb.makeExtra2(levels, Qno);
String showextra3 = myDb.makeExtra3(levels, Qno);
String showextra4 = myDb.makeExtra4(levels, Qno);
// String showextra4 =myDb.makeanswers(levels, Qno);
showQuestion.setText(shoow);
r0.setText(showextra1);
r1.setText(showextra2);
r2.setText(showextra3);
r3.setText(showextra4);
and in the onclick() method trying to check the data but it is showing only first radio button answer as correct if the data is correct only.
public void onClick(View v) {
strat = System.currentTimeMillis();
data = myDb.makeanswers(levels, Qno);
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.bsubmit:
if (r0.isChecked() == true)
{
if (r0.getText().toString().equalsIgnoreCase(data)) {
showAnswer.setText("your answer is correct:" +r0.getText());
} else {
showAnswer.setText("your answer is wrong.the answer is:"
+ data);
}
}
if (r1.isChecked() == true)
{
if (r1.getText().toString().equalsIgnoreCase(data)) {
showAnswer.setText("your answer is correct:" + r1.getText());
} else {
showAnswer.setText("your answer is wrong.the answer is:"
+ data);
}

回答1:
please try to do like this
case R.id.save_profile:
if(((RadioButton)findViewById(R.id.radio0)).isChecked()){
Answer=(RadioButton)findViewById(R.id.radio0)).getText().toString();
}
if(((RadioButton)findViewById(R.id.radio1)).isChecked()){
Answer=(RadioButton)findViewById(R.id.radio0)).getText().toString();
}
// compare here your option......
break;
after that you need to compare the answer with checked button.
回答2:
your code is perfect. it works for me. Just check if your database retrievals and method makeanswer() are correct.
回答3:
rb1=(RadioButton)findViewById(R.id.rb1);
rb2=(RadioButton)findViewById(R.id.rb2);
rb3=(RadioButton)findViewById(R.id.rb3);
rb4=(RadioButton)findViewById(R.id.rb4);
rb1.setText("");//get from database options
rb2.setText("");//get from database options
rb3.setText("");//get from database options
rb4.setText("");//get from database options
//***********onclick of submit button{
int rd1=r_group.getCheckedRadioButtonId();
String textt = "" ;
/************for error if not click on radio btn**********************/
if(rd1==-1)
{
{
AlertDialog ad=new AlertDialog.Builder(Mind_Boost_First.this).create();
ad.setTitle("error");
ad.setMessage("plz select any radio button");
ad.setIcon(R.drawable.cross);
ad.setButton("ok",new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface paramDialogInterface, int paramInt) {
// TODO Auto-generated method stub
}
});
ad.show();
}}
/****************************** get radio checked to textt**************************/
else
{
switch(rd1)
{
case R.id.rb1:
textt =rb1.getText().toString().trim();
Log.e("rrrrrrrrbbbbbbbb11111111",""+rb1.getText().toString().trim());
break;
case R.id.rb2:
textt = rb2.getText().toString().trim();
Log.e("rrrrrrrrbbbbbbbb222222222",""+rb1.getText().toString().trim());
break;
case R.id.rb3:
textt = rb3.getText().toString();
Log.e("rrrrrrrrbbbbbbbb3333333333",""+rb1.getText().toString().trim());
break;
case R.id.rb4:
textt = rb4.getText().toString();
Log.e("rrrrrrrrbbbbbbbb4444444444",""+rb1.getText().toString().trim());
break;
}
/*get correct value in str*/
String str=c.getString(6).trim();
r_group.clearCheck();
/*reset value of lable */
This is my snippet of code that works perfect for me
