In my project, im going to make a multiple choice type question. I can select the questions and answer from mysql, however, i cant do the "matching" of the answer between input answer and the data from mysql. I tried some solutions but they doesnt work as well. I need a big help on it. Below are my codes.
the java class that make multiple choice
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.normalmode);
new DataAsyncTask().execute();
}
public void onClick(View v){
inputtext = ((Button) v).getText().toString();
tv3 = (TextView)findViewById(R.id.textView3);
tv3.setText(inputtext);
if(inputtext == tv2.getText().toString()){
playerscore +=5;
} else {
playerscore +=1;
}
score.setText("Scores : " + playerscore);
new DataAsyncTask().execute();
}
class DataAsyncTask extends AsyncTask<String, String, String>{
@Override
protected String doInBackground(String... param) {
String result = DBConnector.executeQuery("SELECT * FROM questions ORDER BY RAND( ) LIMIT 1");
return result;
}
@Override
protected void onPostExecute(String result) {
question = (TextView)findViewById(R.id.textView_question);
fchoice = (Button)findViewById(R.id.Btn_choice1);
schoice = (Button)findViewById(R.id.Btn_choice2);
tchoice = (Button)findViewById(R.id.Btn_choice3);
tv2 = (TextView)findViewById(R.id.textView2);
score = (TextView)findViewById(R.id.textView_score);
try {
JSONArray jsonArray = new JSONArray(result);
JSONObject jsonData = jsonArray.getJSONObject(0);
question.setText(jsonData.getString("q_desc"));
fchoice.setText(jsonData.getString("fchoice"));
schoice.setText(jsonData.getString("schoice"));
tchoice.setText(jsonData.getString("tchoice"));
ans = jsonData.getString("q_ans");
tv2.setText(ans);
} catch(Exception e) {
Log.e("log_tag", e.toString());
}
}
}
}
three buttons are sharing same onClick in xml file by using
android:onClick="onClick"
the current problem i faced is that it always return "false" no matter i pressed which button. also, is there any way to store/pass "previous" async task data?
I have tried using internal storage but it doesnt work as well
EDIT:
my xml file
