You can use this :
If(rightAnswer){
// If you're in an activity:
answerBtn1.setBackgroundColor(getResources().getColor(R.color.green));
// OR, if you're not:
answerBtn1.setBackgroundColor(Button11.getContext().getResources().getColor(R.color.green));
}
Or, alternatively:
if(rightAnswer){
answerBtn1.setBackgroundColor(Color.GREEN); // From android.graphics.Color
}

ORMLite DISTINCT With Where Condition

I am developing an android project using ORMLite and i have a problem to figure out. There is a picture below and how can i use DISTINCT sql query in ORMLite?
I have some parameters giving to where condition and according to this conditions i am getting number list...
In this picture you are going to see some numbers and some of these numbers are same but i don't want to get same numbers so how can i use DISTINCT in ORMLite with where condition.
Thanks for helping
Also some of my code is like this:
private void modalShowEbat() {
dbHelper = (DBHelper) OpenHelperManager.getHelper(this, DBHelper.class);
RuntimeExceptionDao<Segment, Integer> segmentDao = dbHelper.getSegmentExceptionDao();
List<Segment> list = segmentDao.queryForEq(Constant.QUERY_SEGMENT, editTextSegment.getText().toString().trim());
final CharSequence items[] = new CharSequence[list.size()];
for (int i = 0; i < list.size(); i++) {
items[i] = list.get(i).getColumnEbat();
}
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Segment seçiniz");
builder.setSingleChoiceItems(items, 0, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// the user clicked on colors[which]
editTextEbat.setText(items[which].toString());
if (alertDialog != null && alertDialog.isShowing()) {
alertDialog.dismiss();
}
}
});
alertDialog = builder.create();
alertDialog.show();
}
This is my image of result

Use this -
segmentDao.queryBuilder().distinct().where().eq("name", "value").query();

Hi I solved my problem with below code. Maybe you can say this is long way for this. I wrote my code like below because i couldn't do other ways(using .distinct() method in ORMLite or other ORMLite's method)
If you have any other ways to solve this, i am waiting your suggestions. Thanks for everybody, happy coding...
private void modalShowEbat() {
dbHelper = (DBHelper) OpenHelperManager.getHelper(this, DBHelper.class);
RuntimeExceptionDao<Segment, Integer> segmentDao = dbHelper.getSegmentExceptionDao();
List<Segment> list = segmentDao.queryForEq(Constant.QUERY_SEGMENT, editTextSegment.getText().toString().trim());
GenericRawResults<String[]> rawResults = segmentDao.queryRaw("SELECT DISTINCT Ebat FROM Segment WHERE Segment = ? ", editTextSegment.getText().toString().trim());
final CharSequence items[] = new CharSequence[list.size()];
int i = 0;
for (String[] resultColumns : rawResults) {
String author = resultColumns[0];
items[i] = author;
i++;
}
int newLenght = 0;
for (int j = 0; j < items.length; j++) {
if (items[j] != null) {
newLenght++;
}
}
final CharSequence newItems[] = new CharSequence[newLenght];
for (int j = 0; j < newLenght; j++) {
if (items[j] != null) {
newItems[j] = items[j];
}
}

Two-Dimensional Array with JSON data - Data is downloaded, but I can't access it (?)

So, I am creating a little trivia game for learning purposes, but I ran into a problem.
First, I had a specific Android Fragment obtaining the data from JSON, and I will simply use that data on the callback method and display it on TextViews and Buttons. Everything was working fine, however, every time I returned to that fragment, the same questions would be there. So I decided to handle that in a better way outside of the callback method.
The problem here is that apparently my Arrays are either null or their lengths is zero. Which is weird, because according to my LOG, data is being passed to those arrays on the callback method.
Here's my full fragment code. Thanks!
public class GameFragment extends Fragment {
private TextView txtQuestion;
private Button btnAnswer1;
private Button btnAnswer2;
private Button btnAnswer3;
private Button btnAnswer4;
private Questions[] gameQuestions;
private Questions[] animeQuestions;
private Questions[] techQuestions;
private Questions[] movieQuestions;

Callback cb = new Callback<MyApiData>(){
#Override
public void success(MyApiData myApiData, Response response) {
gameCategories[0] = new Questions[myApiData.getCategory()[0].getQuestions(0).length];
gameCategories[1] = new Questions[myApiData.getCategory()[1].getQuestions(1).length];
gameCategories[2] = new Questions[myApiData.getCategory()[2].getQuestions(2).length];
gameCategories[3] = new Questions[myApiData.getCategory()[3].getQuestions(3).length];
//gameCategories = new Questions[][] {gameQuestions, animeQuestions, techQuestions, movieQuestions};
for(int i = 0; i < 4 ; i++){
for(int j = 0; j < gameCategories[i].length ; j++){
gameCategories[i][j] = myApiData.getCategory()[i].getQuestions(i)[j];
//Log.d("GameFragment", "gameCategories[i][j] - gameCategories["+i+"]["+j+"]: " + gameCategories[i][j].getQuestion());
}

btnAnswer3.setText(gameCategories[category][randomQuestion].getAnswers().getA3());
btnAnswer4.setText(gameCategories[category][randomQuestion].getAnswers().getA4());
}
}
}
}
PS: On my main activity, I check to see which fragment should be loaded. If it's the fragment that contains the components to display the questions and answer (the one from the code above), I call the following method: gameFragment.launchRingDialog(); (and yes, I have created an instance of my GameFragment fragment before calling that method!)

When onResume() is called, your RestClient.get().getQuestions(cb) is still running in background, and your call displayQuestion(), so of course nothing is shown.
Can you put displayQuestion() inside success() of your callback?
Callback cb = new Callback<MyApiData>(){
#Override
public void success(MyApiData myApiData, Response response) {
....
for(int i = 0; i < 4 ; i++){
for(int j = 0; j < gameCategories[i].length ; j++){
...
}
}
displayQuestion();
}
....
};
I would also suggest you to remove displayQuestion() in onResume() method.

ArrayIndexOutOfBoundsException / passing arraylist from alertdialog to activity

I have an alertdialog with multiple choices, I store the user's choices on an ArrayList of strings, and I want to pass the stored arraylist to the host activity (I will use the array's elements to query my database)..
When i run my app, i get an ArrayIndexOutOfBoundsException (may be the index is -1..), I'm not sure if it's the loop, or if i did not pass the arraylist correctly from the alertdialog...
can you guys take a look ? here is my function :
public void onOkay(ArrayList<String> selected) {
StringBuilder stringBuilder = new StringBuilder();
if (selected.size() != 0) {
for (int i = 0; i < selected.size(); i++) {
String categories = selected_items_array[selected.indexOf(i)];
stringBuilder = stringBuilder.append(" " + categories);
}
Toast.makeText(this, "You have selected: "
+ stringBuilder.toString(), Toast.LENGTH_SHORT).show();
}
}
logcat :
java.lang.ArrayIndexOutOfBoundsException: length=6; index=-1
at com.hichamridouane.smartshop.MainActivity.onOkay(MainActivity.java:164)
at com.hichamridouane.smartshop.TimelineSettings$2.onClick(TimelineSettings.java:71)
here is my dialogfragment class.
and here is my host activity.(as I said, i'm not sure if i'm passing correctly the arraylist to the host activity)
thanks !

It looks really strange to me, especially in
String categories = selected_items_array[selected.indexOf(i)];
From JavaDocs about indexOf
Returns the index of the first occurrence of the specified element
in this list, or -1 if this list does not contain the element.
More formally, returns the lowest index <tt>i</tt> such that
<tt>(o==null ? get(i)==null : o.equals(get(i)))</tt>,
or -1 if there is no such index.
So, you try to find element in your selected_items_array (not correct name in Java)
in first iteration i == 0, selected_items_array have no such element => indexOf return -1. Array can't have element with index = -1, it starts from 0. So you have your ArrayIndexOutOfBoundsException

Problem solved. Had to use Arraylists of integers in my activity and my dialogfragment.
here is what i did in my DialogFragment class:
public class TimelineSettings extends DialogFragment {
ArrayList<Integer> selected_categories = new ArrayList<Integer>();
boolean[] itemsChecked = {false, false, false, false, false, false};
// this interface to communicate with the host activity.
public interface dialoglistener {
public void onOkay(ArrayList<Integer> selected);
public void onCancel();
}
dialoglistener mlistener;
//this function is to instantiate the dialoglistener
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mlistener = (dialoglistener) activity;
} catch (ClassCastException e) {
throw new ClassCastException(activity.toString()
+ " must implement dialogListener");
}
}
My multichoice dialog :
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
for(int i=0;i<itemsChecked.length;i++){
if(selected_categories.contains((String)String.valueOf(i)))
itemsChecked[i]=true;
}
// Set the dialog title
builder.setTitle("Choisissez vos paramètres")
.setMultiChoiceItems(R.array.categories, itemsChecked,
new DialogInterface.OnMultiChoiceClickListener() {
#Override
public void onClick(DialogInterface dialog, int indexselected,
boolean isChecked) {
if (isChecked) {
// If the user checked the item, add it to the selected items
if(!selected_categories.contains(indexselected)){
selected_categories.add(indexselected);
itemsChecked[indexselected]=true;
}
} else if (selected_categories.contains(indexselected)) {
// Else, if the item is already in the array, remove it
selected_categories.remove(indexselected);
itemsChecked[indexselected]=false;
}
}
})
// Set the action buttons
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
mlistener.onOkay(selected_categories);
}
})
.setNegativeButton("Annuler", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
mlistener.onCancel();
}
});
return builder.create();
}
On my host activity, I implemented the fragment's interface :
#Override
public void onCreate(Bundle savedInstanceState) {
/* some fancy stuff */
Resources res = getResources();
selectedArray = res.getStringArray(R.array.categories);
}
Getting the selected items (and show them on a toast, just for testing) :
#Override
public void onOkay(ArrayList<Integer> selected) {
StringBuilder stringBuilder = new StringBuilder();
if (selected.size() != 0) {
for (int i = 0; i < selected.size(); i++) {
String categories = selectedArray[selected.get(i)];
stringBuilder = stringBuilder.append(" " + categories);
}
Toast.makeText(this, "You have selected: "
+ stringBuilder.toString(), Toast.LENGTH_SHORT).show();
}
}

Setting one element in array changes others

I checked other similar tags with almost same title. Those answers were not relevant
When setting element at one position of array, both the elements have the same value.

When index is 0, when set command is executed, it also changes the the value at index position '1'.
Can anyone help me with this?
Thanks in Advance,

When index is 0, when set command is executed, it also changes the the value at index position '1'. Can anyone help me with this?
You are definitely mistaken as to what it is causing this. Setting the value at one position of an ArrayList WILL NOT mysteriously cause the value at another position to change. It simply does not work like that.
The effect you are observing will be due to something else:
maybe the value of index is not what you expect
maybe the value of event.values is not what you expect. (Maybe you've made a mistake in the way that you create the Event objects, and they are all sharing one float[] object.)
maybe the value at position 1 was already that value
maybe you've got multiple threads updating the sensorValues list.
