I am building a quiz app in which user selects one of the radioButton from each one cards(each card contains one question with four options) and on pressing the submit floatingActionButton the user can see which has he/she solved on the next Activity .A checkbox below a question number means that he has solved that question. I have searched everywhere but cant get anything helpful.I am stuck in my project.Here are my Codes MainActivity.java
package com.pratyush.onlineexamapp;
public class MainActivity extends AppCompatActivity {
private ArrayList<ModelClass> questionList = new ArrayList<>();
private RecyclerView recyclerView;
FloatingActionButton fabactsbmt,fabctprv;
private QuestionAdapter qAdapter;
private static final String FORMAT = "%02d:%02d";
private RadioGroup rg;
private RadioButton rb;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView) findViewById(R.id.rcyclvw);
final TextView timer=(TextView)findViewById(R.id.timer) ;
int selectedId=rg.getCheckedRadioButtonId();
rb=(RadioButton)findViewById(selectedId);
qAdapter= new QuestionAdapter(this);
fabactsbmt=(FloatingActionButton)findViewById(R.id.sbmtBtn);
fabctprv=(FloatingActionButton)findViewById(R.id.prevwBtn);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL, false);
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
recyclerView.setAdapter(qAdapter);
fabctprv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent it= new Intent(MainActivity.this,PreviewDetails.class);
String selectedFromList = (recyclerView.getItemAtPosition(position));
it.putIntegerArrayListExtra("Respone",);
rg.clearCheck();
startActivity(it);
}
});
fabactsbmt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(MainActivity.this,"Your test will be submitted without taking you to Preview Activity",Toast.LENGTH_SHORT).show();
}
});
new CountDownTimer(60000, 1000) { // adjust the milli seconds here
public void onTick(long millisUntilFinished) {
timer.setText("Time Left:" + " " + String.format(FORMAT,
TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished) - TimeUnit.HOURS.toMinutes(
TimeUnit.MILLISECONDS.toHours(millisUntilFinished)),
TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) - TimeUnit.MINUTES.toSeconds(
TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished))) + "/01:00");
}
public void onFinish() {
AlertDialog.Builder builder = new AlertDialog.Builder(
MainActivity.this);
builder.setTitle("Time Out!!!");
builder.setMessage("Your Score is" + " " + 100);
builder.setCancelable(false);
