I need to hide a radio button in a quiz app android

I would like to ask for some help with my android code. I am trying to develop a quiz app using SQLite.Number of possible answers differs so i need to hide radio buttons from the main screen if answers e.g. are 3 and not 4 (4 is by default the number of the radio buttons). Tried to use:
if (DataContract.QuestionTable.COLUMN_ANSWER4.isEmpty ()){ radioButton4.setVisibility (View.INVISIBLE); }
but does not seem to work.I'm new in android programming and this is my first project so every comment will be very helpful. Thank you.

Here's a demo with a suggested technique, considering the limited amount of code posted with the question.
This utilises two tables to conform with a normalised approach. A table for the questions and a table for answers. Each answer (the Children) has a link/map/relationship/association with a single Question (the Parent). To prevent referential integrity issues a Foreign Key constraint has been used.
First a few POJO's for the Questions, the Answers and QuestionWithAnswers (i.e. it's answers)
QuestionPOJO
class QuestionPOJO {
long questionId;
String questionText;
public QuestionPOJO(long questionId, String questionText) {
this.questionId = questionId;
this.questionText = questionText;
}
public long getQuestionId() {
return questionId;
}
public void setQuestionId(long questionId) {
this.questionId = questionId;
}
public String getQuestionText() {
return questionText;
}
public void setQuestionText(String questionText) {
this.questionText = questionText;
}
}
AnswerPOJO
class AnswerPOJO {
long answerId;
long questionMap;
String answerText;
boolean correct = false;
public AnswerPOJO(long answerid, long questionMap, String answerText, boolean correct) {
this.answerId = answerid;
this.questionMap = questionMap;
this.answerText = answerText;
this.correct = correct;
}
public long getAnswerId() {
return answerId;
}
public void setAnswerId(long answerId) {
this.answerId = answerId;
}
public long getQuestionMap() {
return questionMap;
}
public void setQuestionMap(long questionMap) {
this.questionMap = questionMap;
}
public boolean isCorrect() {
return correct;
}
public void setCorrect(boolean correct) {
this.correct = correct;
}
public String getAnswerText() {
return answerText;
}
public void setAnswerText(String answerText) {
this.answerText = answerText;
}
}
and QuestionWithAnswerPOJO
class QuestionWithAnswersPOJO {
QuestionPOJO question;
ArrayList<AnswerPOJO> answers = new ArrayList<>();
public QuestionWithAnswersPOJO(QuestionPOJO question, List<AnswerPOJO> answers) {
this.question = question;
this.answers.clear();
this.answers.addAll(answers);
}
public QuestionPOJO getQuestion() {
return question;
}
public void setQuestion(QuestionPOJO question) {
this.question = question;
}
public ArrayList<AnswerPOJO> getAnswers() {
return answers;
}
public void setAnswers(ArrayList<AnswerPOJO> answers) {
this.answers = answers;
}
}
Now the DatabaseHelper, that handles all the database activity. Including methods to add and get Questions and the Answers and notably to get the Answers that belong to a question.
class DatabaseHelper extends SQLiteOpenHelper {
public static final String DATABASE_NAME = "questions.db";
public static final int DATABASE_VERSION = 1;
public static final String QUESTION_TABLE = "question";
public static final String QUESTION_ID_COLUMN = BaseColumns._ID;
public static final String QUESTION_TEXT_COLUMN = "question_text";
public static final String ANSWER_TABLE = "answer";
public static final String ANSWER_ID_COLUMN = BaseColumns._ID;
public static final String ANSWER_TEXT_COLUMN = "answer_text";
public static final String ANSWER_QUESTION_MAP_COLUMN = "question_map";
public static final String ANSWER_CORRECT_COLUMN = "correct";
private static volatile DatabaseHelper instance = null;
private DatabaseHelper(Context context) {
super(context,DATABASE_NAME,null,DATABASE_VERSION);
}
private static SQLiteDatabase db = null;
public static DatabaseHelper getInstance(Context context, boolean forceOpen) {
if (instance == null) {
instance = new DatabaseHelper(context);
}
if (forceOpen) {
db = instance.getWritableDatabase();
}
return instance;
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE IF NOT EXISTS " + QUESTION_TABLE + "(" +
QUESTION_ID_COLUMN + " INTEGER PRIMARY KEY," +
QUESTION_TEXT_COLUMN + " TEXT" +
");");
db.execSQL("CREATE TABLE IF NOT EXISTS " + ANSWER_TABLE + "(" +
ANSWER_ID_COLUMN + " INTEGER PRIMARY KEY," +
ANSWER_TEXT_COLUMN + " TEXT," +
ANSWER_QUESTION_MAP_COLUMN + " INTEGER REFERENCES " + QUESTION_TABLE + "(" + QUESTION_ID_COLUMN + ") ON DELETE CASCADE ON UPDATE CASCADE," +
ANSWER_CORRECT_COLUMN + " INTEGER DEFAULT 0 /* false */" +
");");
}
#Override
public void onUpgrade(SQLiteDatabase db, int i, int i1) {
}
// Fully comprehensive Question insert
public long insertQuestion(Long questionId, String questionText) {
init_db_AsWriteableDatabase();
long rv = -2;
ContentValues cv = new ContentValues();
if (questionId != null && questionId > 0) {
cv.put(QUESTION_ID_COLUMN,questionId);
}
if (questionText != null && questionText.length() > 0) {
cv.put(QUESTION_TEXT_COLUMN,questionText);
}
if (cv.size() > 0) {
rv = db.insert(QUESTION_TABLE,null,cv);
}
return rv;
}
// Concise Question insert
public long insertQuestion(String questionText) {
return insertQuestion(null,questionText);
}
// Fully comprehensive Answer insert
public long insertAnswer(Long answerId, long questionMap, String answerText, boolean correct) {
init_db_AsWriteableDatabase();
long rv = -2;
ContentValues cv = new ContentValues();
if (answerId != null && answerId > 0) {
cv.put(ANSWER_ID_COLUMN,answerId);
}
if (answerText != null && answerText.length() > 0) {
cv.put(ANSWER_CORRECT_COLUMN,correct);
cv.put(ANSWER_TEXT_COLUMN,answerText);
cv.put(ANSWER_QUESTION_MAP_COLUMN,questionMap);
rv = db.insert(ANSWER_TABLE,null,cv);
}
return rv;
}
// long concise Answer insert
public long insertAnswer(long questionMap, String answerText, boolean correct) {
return insertAnswer(null,questionMap,answerText,correct);
}
public long insertAnswer(long questionMap, String answerText) {
return insertAnswer(questionMap,answerText,false);
}
// short concise Answer insert
private void init_db_AsWriteableDatabase() {
if (db == null) {
db = this.getWritableDatabase();
}
}
#SuppressLint("Range")
public QuestionPOJO getQuestionById(long questionId) {
QuestionPOJO rv = null;
init_db_AsWriteableDatabase();
Cursor csr = db.query(QUESTION_TABLE,null,QUESTION_ID_COLUMN+"=?",new String[]{String.valueOf(questionId)},null,null,null);
if (csr.moveToNext()) {
rv = new QuestionPOJO(csr.getLong(csr.getColumnIndex(QUESTION_ID_COLUMN)),csr.getString(csr.getColumnIndex(QUESTION_TEXT_COLUMN)));
}
csr.close();
return rv;
}
#SuppressLint("Range")
public List<AnswerPOJO> getAnswersForQuestion(long questionId, boolean onlyCorrect) {
init_db_AsWriteableDatabase();
ArrayList<AnswerPOJO> rv = new ArrayList<>();
StringBuilder whereClause = new StringBuilder();
whereClause.append(ANSWER_QUESTION_MAP_COLUMN + "=?");
if (onlyCorrect) {
whereClause.append(" AND ").append(ANSWER_CORRECT_COLUMN);
}
Cursor csr = db.query(ANSWER_TABLE,null,whereClause.toString(),new String[]{String.valueOf(questionId)},null,null,null);
while (csr.moveToNext()) {
rv.add(
new AnswerPOJO(
csr.getLong(csr.getColumnIndex(ANSWER_ID_COLUMN)),
questionId,
csr.getString(csr.getColumnIndex(ANSWER_TEXT_COLUMN)),
csr.getInt(csr.getColumnIndex(ANSWER_CORRECT_COLUMN)) > 0
)
);
}
csr.close();
return rv;
}
}
Finally to put it all together and activity that has a layout for 4 radio buttons along with the associated answer as a TextView.
So the layout is:-
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!">
</TextView>
<RadioGroup
android:id="#+id/question_radiogroup"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<RadioButton
android:id="#+id/answer1_radioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:ignore="DuplicateSpeakableTextCheck"></RadioButton>
<TextView
android:id="#+id/answer1_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<RadioButton
android:id="#+id/answer2_radioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RadioButton>
<TextView
android:id="#+id/answer2_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<RadioButton
android:id="#+id/answer3_radioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RadioButton>
<TextView
android:id="#+id/answer3_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<RadioButton
android:id="#+id/answer4_radioButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</RadioButton>
<TextView
android:id="#+id/answer4_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
</RadioGroup>
</LinearLayout>
simple enough to show how hiding the buttons depending upon the number of answers (or a limit according to the number of Buttons/Textviews)
And the activity to demonstrate:-
public class MainActivity extends AppCompatActivity {
DatabaseHelper dbHelper;
RadioButton[] radiobuttons = new RadioButton[4];
TextView[] answerTexts = new TextView[4];
QuestionWithAnswersPOJO currentQuestionWithAnswers;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/*
prepare Radion Buttons and associated TextViews
*/
radiobuttons[0] = this.findViewById(R.id.answer1_radioButton);
radiobuttons[1] = this.findViewById(R.id.answer2_radioButton);
radiobuttons[2] = this.findViewById(R.id.answer3_radioButton);
radiobuttons[3] = this.findViewById(R.id.answer4_radioButton);
answerTexts[0] = this.findViewById(R.id.answer1_textview);
answerTexts[1] = this.findViewById(R.id.answer2_textview);
answerTexts[2] = this.findViewById(R.id.answer3_textview);
answerTexts[3] = this.findViewById(R.id.answer4_textview);
/*
Prepare to use Database
*/
dbHelper = DatabaseHelper.getInstance(this,true);
SQLiteDatabase db = dbHelper.getWritableDatabase();
/* Clear any existing data for consistent results */
db.delete(DatabaseHelper.ANSWER_TABLE,null,null);
db.delete(DatabaseHelper.QUESTION_TABLE,null,null);
/* Add some demo data 1 question with 5 answers (comment out to reduce number of answers)*/
long q1id = dbHelper.insertQuestion("What is 1 + 1");
dbHelper.insertAnswer(q1id,"It is 1");
dbHelper.insertAnswer(q1id,"it is 2", true);
dbHelper.insertAnswer(q1id,"It is 3");
dbHelper.insertAnswer(q1id,"It is 4");
dbHelper.insertAnswer(q1id,"It is something Else"); // will be ignored because only 4 radio buttons
/* Get the question with the answers, however many ot has */
currentQuestionWithAnswers = new QuestionWithAnswersPOJO(dbHelper.getQuestionById(q1id),dbHelper.getAnswersForQuestion(q1id,false));
/* setup (refresh) the radio buttons and textviews */
getAndSetRadioButtons(currentQuestionWithAnswers);
}
/*
Does as it says
*/
private void getAndSetRadioButtons(QuestionWithAnswersPOJO qwa) {
// Clear All
for (int i=0;i < radiobuttons.length; i++) {
radiobuttons[i].setVisibility(View.GONE);
answerTexts[i].setText("");
answerTexts[i].setVisibility(View.GONE);
}
/* show only the least of answers/radio buttons */
int numberToShow = radiobuttons.length;
if (qwa.answers.size() < radiobuttons.length) {
numberToShow = qwa.answers.size();
}
int i = 0;
for(AnswerPOJO a: qwa.answers) {
if (i < numberToShow) {
radiobuttons[i].setVisibility(View.VISIBLE);
answerTexts[i].setVisibility(View.VISIBLE);
answerTexts[i++].setText(a.answerText);
} else {
/* nothing more to do so early break out of the loop */
break;
}
}
}
}
Results
Result 1 - run with the 5 answers (see comments re 5th answer)
Result 2 - All bar 1 answer comment out so the question has just the 1 answer
The code used:-
long q1id = dbHelper.insertQuestion("What is 1 + 1");
dbHelper.insertAnswer(q1id,"It is 1");
//dbHelper.insertAnswer(q1id,"it is 2", true);
//dbHelper.insertAnswer(q1id,"It is 3");
//dbHelper.insertAnswer(q1id,"It is 4");
//dbHelper.insertAnswer(q1id,"It is something Else"); // will be ignored because only 4 radio buttons
The display :-
Result 3 - first and 5th answers only inserted
and so on.
Additional after code has been posted.
Additional Answer as code has now been added.
You say:-
Tried to use:
if (DataContract.QuestionTable.COLUMN_ANSWER4.isEmpty ()){ radioButton4.setVisibility (View.INVISIBLE); }
but does not seem to work.
If DataContract.QuestionTable.COLUMN_ANSWER4 were empty then would be facing more serious issues as it is the column name.
You should be checking for the contents of the column which has been retrieved from DB and placed into currentQuestion, for the question being inspected.
I believe that using (old code commented out):-
radioButton1.setText(currentQuestion.getAnswer1 ());
radioButton2.setText(currentQuestion.getAnswer2 ());
radioButton3.setText(currentQuestion.getAnswer3 ());
radioButton4.setText(currentQuestion.getAnswer4 ());
if(currentQuestion.getAnswer4() == null || currentQuestion.getAnswer4().isEmpty()) {
radioButton4.setVisibility(View.INVISIBLE);
} else {
radioButton4.setVisibility(View.VISIBLE); // just in case it is INVISIBLE
radioButton4.setText(currentQuestion.getAnswer4());
}
/*
if (DataContract.QuestionTable.COLUMN_ANSWER4.isEmpty ()){
radioButton4.setVisibility (View.INVISIBLE);
} else {
radioButton4.setText(currentQuestion.getAnswer4 ());
}
*/
Will resolve this issue. e.g. at Q3:-

Adding a new drawable it is changing the icons of the parsed xml

I am facing with a problem which happens only when I add new drawable.
I have a parsed xml to Fragment the icon is set like int.
If I add new drawable then it chooses random drawables to show the icons for the parsed xml.
I have an Adapter for the RecyclerListView.
A Pojo class and DB which extends SQLiteOpenHelper.
If I clear the cache and Storage then it back to normal,
or if I delete the new added drawable it returns back to normally.
Can someone help me to know why it is affecting to change the icons.
I have tried to clean project and rebuild the same.
Invalidate cache and restart but still the same.
Below you can find the code and below the code two pictures of the problem.

I have created a LogCat to show what it takes this is the result.
Right way
drawable/youtube
drawable/facebook
drawable/twitter
After add drawable or vector asset or image
drawable/wiki
drawable/facebook
drawable/trash

You're calling String.valueOf(bookmark.getIcon()) to store the icon in your database. As the icon is an int representing the resource, this stores the resource id as a string. The issue now is that resource ids are not stable and might change any time you create a new APK. Therefore it works while you don't update the app, but starts failing after.
Instead you should store the name of the res and keep these stable. You're already using the name with your XML data, so I'd assume that's your goal anyhow.
mDB.addBookmark(
Long.valueOf(bookmark.getId()),
bookmark.getName(),
bookmark.getViewType() > 0,
iconName(bookmark.getIcon()),
bookmark.getNativeUrl(),
bookmark.getSearchUrl()
);
String Icon = csr.getString(csr.getColumnIndex(COL_ICON));
b.setIcon(iconRes(Icon));
Now you only need to implement the mapping from name to id.
String iconName(int icon) {
return getResources().getResourceEntryName(icon);
}
int iconRes(String icon) {
return getResources().getIdentifier(icon, "drawable", mContext.getPackageName())
}
Also you need to unset mContext on detach or don't store it and use getContext() or requireContext() instead. Of course you'd have to check for null if you use it in some background operation.
#Override
public void onDetach() {
mContext = null;
super.onDetach();
}

Try to do myAdapter.notifyDataSetChanged(); after your arrayList adding work in the FragmentBookmark:
Bookmark bookmark = new Bookmark();
bookmark.setViewType(1);
bookmark.setIcon(R.drawable.add_new_bookmark_icon);
arrayList.add(bookmark);
myAdapter.notifyDataSetChanged();
BTW:The xml parse work and database operations should generally be handled asynchronously.
Updated：Change your the type icon field in Bookmark from int to String,and modify some code in loadBookMarksFromXML,from
int drawableResourceId =
getResources().getIdentifier(
xpp.getAttributeValue(null, "icon"), "drawable",mContext.getPackageName());
bookmark.setIcon(drawableResourceId);
to
bookmark.setIcon(xpp.getAttributeValue(null, "icon"));
change some code in onBindViewHolder in class MyAdapter,from:
int resID = context.getResources().getIdentifier(String.valueOf(arrayList.get(position).getIcon()), "drawable", context.getPackageName());
to
int resID = context.getResources().getIdentifier(arrayList.get(position).getIcon()), "drawable", context.getPackageName());
You can easily fix other errors caused by changing the icon field's type and run again,let me know the result.Thx.

For storing image to sqlite or any other local database you must store name of variable(i do this when use local database maybe there is better way)
So when you want to store drawable
Use this code
bookmark.setIcon("add_new_bookmark_icon");//don't forget to change icon to String in bookmark
Instead of this
bookmark.setIcon(R.drawable.add_new_bookmark_icon);//you use this in onViewCreate and buildBookmarkArrayListfromDB
Now when you want show drawable from database use this code
int resourceId = getResources().getIdentifier("", "drawable", getPackageName());
Drawable yourImage = ContextCompat.getDrawable(this,resourceId);
imageView.setImageDrawable(yourImage);
Note
You must change all place use setIcon or getIcon and all code you use icon as int like in getAllBookmarks -> csr.getInt(csr.getColumnIndex(COL_ICON) and others
I do this several years ago and i don't check it still works. try it and tell me what happens

As the Resource id will be kept on changing at every install or apk generation, it is wise to store the name of the icon resource and fetch it during display time. To do this you can store a string value of the name of the icon(you can also use the same name as of the bookmark, but make sure the drawable of the same name).
Change icon field to String in Database (Bookmark.db) & Pojo.
Remove this line in your Fragment of RecyclerView
int drawableResourceId = getResources().getIdentifier(xpp.getAttributeValue(null, "icon"), "drawable", mContext.getPackageName());
Change next line
bookmark.setIcon(xpp.getAttributeValue(null, "name"));
In onBindViewHolder in MyAdapter class get icon resource using
int iresourceid = getResources().getIdentifier(arrayList.get(position).getIcon(),"drawable",getPackageName());

Maybe you should move icons from res folder to assets, then load it with Glide.
if (getResources().getAssets().list("").contains("icon.png")) {
Glide.with(fragment)
.load(Uri.parse("file:///android_asset/icon.png"))
.into(imageView);
} else {
// load from web
}

pass Data from a List View (generated from Rest Api) to another activity and save that into SQLite Database

I am creating an android app (still the basic structure, without any design) from an Job site through XML feed using REST api.
Till now, I could managed to parse the XML data, displaying the List View with an POP UP menu item on each row. I am passing Data from PostBaseAdapter to MarkAsFav class. Could You please tell me if I am doing right or not? coz, I am getting no any data saved in database
Now, I have a problems:
I have 3 pop up menu item:
1. Set as Favourite
2. Share on Fb
3. email to Your friend
I am working on point number-1.
For now,I would be saving the data in SQLite Database itself. so, I am passing all the data (all the details about the job with all rows) to another activity, more over I am accepting a user given name to save the details through insertDB() in my Database.
But, unfortunately , nothing is getting saved in the database .
Can you tell me, if the data is getting passed or not and if the datas are being saved in database or not?
Please help me out. Please tell me where and how to modify the code?

try .getText() on your EditText
like yourEditText.getText(); and set it into your NewUserDb and pass the NewUserDb object into addUser method of your DatabaseHelper class

First you declare database create table query string in your DatabaseHelper class like this:
private static final String DATABASE_CREATE_USER = "create table UserInfo("
+ "_id VARCHAR(20)," + "userGOAL VARCHAR(20),"
+ "userName VARCHAR(20)," + "userEmail VARCHAR(20),"
+ "userDOB VARCHAR(20)," + "userHeight VARCHAR(10),"
+ "userWeight VARCHAR(10)," + "userGender VARCHAR(10),"
+ "userZIP VARCHAR(10) "+ ")";
Then write inside onCreate method of DatabaseHelper
db.execSQL(DATABASE_CREATE_USER);
Then declare object of SqliteDatabase and DatabseHelper in your AcountActivity like this:
DatabaseHelper dbHelper;
SQLiteDatabase db;
Afer this write following code inside your button onClick method:
dbHelper= new DatabaseHelper(ActountActivity.this);
db = dbHelper.getWritableDatabase();
ContentValues insertValues = new ContentValues();
insertValues.put("_id", "User_Id");
insertValues.put("userGOAL", "User_Goal");
insertValues.put("userName", "User_Name");
insertValues.put("userEmail", "User_Email");
insertValues.put("userDOB", "User_DOB");
insertValues.put("userHeight", "User_Height");
insertValues.put("userWeight", "User_Weight");
insertValues.put("userGender", "User_Gender");
insertValues.put("userZIP", "User_Zip");
db.insert("UserInfo", null, insertValues);
db.close();
May this help you.

First you'll need to create a layout file that will represent how you want to display each list item.
Then you'll need to extend the BaseAdapter class so that you can decide how you want to display each Kovil class.
Once that is constructed, you can call setAdapter on your ListView.
