I created an app using Android Studio and one of its activity contain questions and their choices using radiobuttons. I created those groupbuttons and radiobuttons programmatically, but the first question can choose two radio button when it shouldn't.
This is my code:
FeedbackFragment.java
try {
loading.setVisibility(View.GONE);
JSONObject jsonObject = new JSONObject(response);
if (!jsonObject.isNull("questions")) {
JSONArray questions = jsonObject.getJSONArray("questions");
LinearLayout.LayoutParams params;
for (int i = 0; i < questions.length(); i++) {
final JSONObject oneQuestion = questions.getJSONObject(i);
if (!oneQuestion.isNull("answers")) {
TextView textQuestion = new TextView(getActivity());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
textQuestion.setLayoutParams(params);
textQuestion.setText(oneQuestion.getString("question_text"));
if(textQuestion.getParent() != null) {
((ViewGroup) textQuestion.getParent()).removeView(textQuestion);
}
layoutFeedback.addView(textQuestion);
groupChoice = new RadioGroup(getActivity());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
params.setMargins(0,0,0,20);
groupChoice.setLayoutParams(params);
groupChoice.setId(Integer.valueOf(oneQuestion.getString("question_id")));
groupChoices.add(groupChoice);
if(groupChoice.getParent() != null) {
((ViewGroup) groupChoice.getParent()).removeView(groupChoice);
}
layoutFeedback.addView(groupChoice);
JSONArray choices = oneQuestion.getJSONArray("answers");
for(int j=0;j<choices.length();j++) {
JSONObject choice = choices.getJSONObject(j);
radioChoice = new RadioButton(getActivity());
radioChoice.setId(Integer.valueOf(choice.getString("answer_id")));
radioChoice.setText(choice.getString("answer_text"));
radioChoice.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
radioChoice.setButtonTintList(new ColorStateList(
new int[][]{
new int[]{-android.R.attr.state_enabled}, //disabled
new int[]{android.R.attr.state_enabled} //enabled
},
new int[] {
Color.BLACK //disabled
,getResources().getColor(R.color.colorPrimary) //enabled
}
));
groupChoice.addView(radioChoice);
}
LinearLayout borderBottom = new LinearLayout(getActivity());
params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
1);
params.setMargins(0, 0, 0, 20);
borderBottom.setLayoutParams(params);
borderBottom.setBackgroundColor(Color.parseColor("#999999"));
borderBottom.setVerticalGravity(Gravity.BOTTOM);
layoutFeedback.addView(borderBottom);
}
}
}
} catch (JSONException e) {
e.printStackTrace();
Toast.makeText(getActivity(), "Error JSON Exception! " + e.toString(), Toast.LENGTH_SHORT).show();
loading.setVisibility(View.GONE);
}
The weird thing is, it only happened at first question, the other question worked fine. What went wrong? Please help.

Iam creating the survey app with firebase Realtimedatabase.I have stored questions in database and getting them in application by dynamically creating RadioButtons,Textview and Edittext.
Now I have to save the filled information from users back to firebase database.I searched and get to know to use setTags but couldnt really able to understand after setting tags how to seperate edittext and radio buttons and get them back separately while pushing them to firebase database.What I want is to get the data from each edittext and radiobutton selected and save them back uniquely in firebase database
Here is the code where Iam creating views dynamically and getting data in them
if (getIntent().hasExtra(Constants.ref_no)) {
surveyRefNo = getIntent().getStringExtra(Constants.ref_no);
}

android.os.NetworkOnMainThreadException
is thrown when an application attempts to perform a network related operation on the main thread.
This is only thrown for applications targeting the Honeycomb SDK or higher versions. Ensure that your application is not attempting to perform any network
related operation on its main thread.
How can I refresh the LinearLayout called "contNoticias" after doing a click in a button?
Here is my code:
contNoticias = (LinearLayout)findViewById(R.id.contNoticias);

After trying loads of methods, I solved it by setting linearLayout's parameters like this
LinearLayout parent = new LinearLayout(SelectCaegory.this);
TableRow.LayoutParams Paramslinear = new TableRow.LayoutParams(dpToPx(150),dpToPx(150));
Your problem is with this line:
LinearLayout parent = new LinearLayout(getApplicationContext());
You are creating a new view but she's not attach to your root view.
Try to declare your LinearLayout on your layout file, and fint it with the ID
LinearLayout parent = (LinearLayout) findViewById(R.id.my_parent_layout);
This is a logic based problem where I will need a small sample of code or an idea supplied for an answer.
I am creating a U.I. programmatically from a JSON response. This app will load in an unknown amount of questions and answers. I'm using loops and conditional statements to create the Views for the U.I. and I am using an AsyncTask for most of the heavy lifting.
Well the problem I can't seem to figure out is: How will I give an unknown amount of views unique id's so that I can use them.
I am providing all the fragment code so you know exactly whats going on:

I probably went about this the wrong way to begin with, however this is where I'm at. I will need to give the EditText an id to grab user input, I will need to give the ImageButton and id so it can perform events with the onClick function, and so on and so forth. You get the point I'm sure. So how would one of you tackle this problem?
It's really hard to answer this question. It really depends on what you want to do with the captured data. In any case, you don't have to generated IDs for the elements, you can set new event listeners using Anonymous classes. Then, each of these listeners can save your data to somewhere depending on your key (name?).
