Refresh the fragment after Camera Intent

I am calling the Camera Intent from one of the fragments to save the image into gallery. The photo is taken and the image also gets saved in the gallery. I also have an adapter which gets all the images stored in the gallery into my application using GridView. So after taking the photo from the Camera Intent, I have to go back to another fragment and come back to see my photo refreshed in the GridView. So basically, I want to refresh the fragment once I am back from the Camera Intent.
Here is the structure. I have a fragment called GalleryHomeFragment, from which I click a button and go to GalleryFragment. From there, I call the Camera Intent. My requirement is to refresh the GalleryFragment, once I come back from taking the picture, to see the pictures in my folders.
Here is what I have tried so far. Posting the necessary code.
GalleryFragment.java
cameraButton = (FloatingActionButton) view.findViewById(R.id.cameraBtn);
cameraButton.setOnClickListener(new View.OnClickListener() {
#Override

Any help is appreciated. Thanks a lot in advance.

I was so stupid and why I don't know it took me so long to figure out the answer.
I did this by restarting the fragment in the onActivityResult() like this.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
Fragment galleryFragment = new GalleryFragment();
FragmentManager fm = getFragmentManager();
fm.popBackStack();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.container_gaFragments, galleryFragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.addToBackStack(null);
ft.commit();
}
}
So each time when the result of activity is a success, I refresh the fragment to the galleryFragment and it works perfect.

Sectioning date header in a ListView that has adapter extended by CursorAdapter

I am trying to build a demo chatting App.I want to show the messages with section headers as Dates like "Today","Yesterday","May 21 2015" etc.I have managed to achieve this but since the new View method gets called whenever I scroll the list.The headers and messages get mixed up.
For simplicity, I have kept the header in the layouts itself and changing its visibility(gone and visible) if the date changes.
Can you help me out with this? Let me know if anyone needs any more info to be posted in the question.

I hope anyone could help me on this. I really need a help right now. Thanks! :)

You can use this
sql_lite_db_obj.delete(tablename, whereClause, whereArgs)
For your convenience i edited my answer
public void clickHandler(View v) {
if (v.getId() == R.id.deleteOrder) {
int _id = 0;
try {
_id = (Integer) v.getTag(R.id.orderTitle);
} catch (Exception e) {
e.printStackTrace();
}
dh.delete(DatabaseHelpere.TableNAME, "_id=?",new String[] { String.valueOf(_id) });
}
}

ListView not displaying proper Sections while using SimpleCursorAdapter

EDITED
I am working on a contact list and trying to implement sectioned listview. When the app gets started, only one of the Header (Section) starts displaying itself after some chunks of items repeatedly and changing its position on scrolling up/down.
Here is my code :
private class MySimpleCursorAdapter extends SimpleCursorAdapter {
Holder holder = null;
LayoutInflater layoutInflater;
// String keyWord = "empty";
public MySimpleCursorAdapter(Context context, int layout, Cursor cur,
String[] from, int[] to, int flag) {
super(context, layout, cur, from, to, flag);
}
public String getTitle(String contName) {
return contName.substring(0, 1);
}
#Override
public View newView(Context context, Cursor mCursor, ViewGroup parent) {
holder = new Holder();
layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
String cont_Name = mCursor.getString(mCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
View view = null;
if ( ! keyWord.equalsIgnoreCase(getTitle(cont_Name)) || keyWord.equals(null))
{
view = layoutInflater.inflate(R.layout.section_header, null);
TextView sectionTitle = (TextView) view.findViewById(R.id.title2);
sectionTitle.setText(getTitle(cont_Name));
keyWord = getTitle(cont_Name);
Log.d("KeyWord", keyWord);
Log.d("Contact Name", cont_Name);
}
else if(keyWord.equalsIgnoreCase(getTitle(cont_Name))) {
view = layoutInflater.inflate(R.layout.pm_fragment, null);
holder.contactTitle= (TextView)view.findViewById(R.id.textView1);
holder.contactDetail = (TextView)view.findViewById(R.id.textView2);
holder.contactTitle.setText(mCursor.getString(mCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
holder.contactDetail.setText(mCursor.getString(mCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
Log.d("KeyWord", keyWord);
Log.d("Contact Name", cont_Name);
String contactId_String = ""+mCursor.getString(mCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID));
long contactId = Long.parseLong(mCursor.getString(mCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone._ID)));
DatabaseHandler handler = new DatabaseHandler(getActivity());
Contact matchedContact = handler.getContact(contactId) ;
String dbContactId= "";
if(matchedContact != null){
if(matchedContact.getID() != 0 && ""+matchedContact.getID() != null){
dbContactId= ""+matchedContact.getID();
}
if(dbContactId.equals(contactId_String)){
holder.myImage = (ImageView) view.findViewById(R.id.imageView1);
holder.myImage.getLayoutParams().height = 100;
holder.myImage.getLayoutParams().width = 100;
holder.myImage.setBackgroundResource(R.drawable.person_empty_online);
}
}else{
holder.myImage = (ImageView) view.findViewById(R.id.imageView1);
holder.myImage.getLayoutParams().height = 100;
holder.myImage.getLayoutParams().width = 100;
holder.myImage.setBackgroundResource(R.drawable.person_empty_offline);
}
handler.close();
keyWord = getTitle(cont_Name);
}
return view;
}
}
During Debugging, After the ending line return view ; , it enters in CursorAdapter.class and passes by through the lines:
if (!mCursor.moveToPosition(position)) {
throw new IllegalStateException("couldn't move cursor to position " + position);
}
and enters in if condtion, but app doesn't crash.

Finally Got my answer my own after two weeks...my if-else conditions were too complex , so i make comparison on some different criteria.
if (mCursor.getPosition() > 0 && mCursor.moveToPrevious())
{
preName = mCursor.getString(mCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
mCursor.moveToNext();
}
else if(mCursor.getPosition() == 0)
{
preName = null;
}
else{
preName = null;
}
if(preName != null){
preTitle = getTitle(preName);
}
//===============================================================================
/*
* Setting Header And Contact Details
*/
//===============================================================================
if(mCursor.isFirst()){
holder.titleText.setVisibility(View.VISIBLE);
holder.titleText.setText(itemTitle);
}
else if(preName != null){
if(! itemTitle.equalsIgnoreCase(preTitle))
{
holder.titleText.setVisibility(View.VISIBLE);
holder.titleText.setText(itemTitle);
}else{
holder.titleText.setVisibility(View.GONE);
}
}
holder.contactTitle.setText(mCursor.getString(mCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
holder.contactDetail.setText(mCursor.getString(mCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));

Android cursor with an int array row, how do I get it?

I am trying to get a simple view to work in android by using a cursor and a provider.
The provider works perfectly but I don't know how to get an int array out of a row in my cursor.
Here's my provider:
public class RecipeProvider extends ContentProvider {
public static final String COL_RECID = "_ID";
public static final String COL_RECCATID = "recipeCategory";
public static final String COL_RECIMGID = "recipeImageID";
public static final String COL_RECDESC = "recipeDescription";
public static final String COL_RECLOC = "recipeLocations";
public static final String[] columnNames = {COL_RECID, COL_RECCATID, COL_RECIMGID, COL_RECDESC, COL_RECLOC };
public static final String AUTHORITY = "be.pxl.minecraftguide.providers.recipeprovider";
public static final Uri CONTENT_URI = Uri.parse("content://" + AUTHORITY + "/*");
private List<Recipe> recipesList;
#Override
public boolean onCreate() {
recipesList = new ArrayList<Recipe>();
recipesList.add(new Recipe(1, 2, R.drawable.diamond_boots, "Boots (Diamond)",
new int[] { 0,0,0, 1,0,1, 1,0,1 }, new int[] { R.drawable.diamond_ingot }));
recipesList.add(new Recipe(2, 2, R.drawable.gold_boots, "Boots (Gold)",
new int[] { 0,0,0, 1,0,1, 1,0,1 }, new int[] { R.drawable.gold_ingot }));
recipesList.add(new Recipe(3, 2, R.drawable.iron_boots, "Boots (Iron)",
new int[] { 0,0,0, 1,0,1, 1,0,1 }, new int[] { R.drawable.iron_ingot }));
return true;
}
#Override
public Cursor query(Uri arg0, String[] categories, String recipeID, String[] arg3,
String arg4) {
MatrixCursor mxCur = new MatrixCursor(columnNames);
RowBuilder rb;
if (categories != null && Integer.parseInt(categories[0]) != 1) {
for (Recipe rcp : recipesList) {
if (rcp.getRecipeCategory() == Integer.parseInt(categories[0])) {
rb = mxCur.newRow();
rb.add(rcp.getRecipeID());
rb.add(rcp.getRecipeCategory());
rb.add(rcp.getRecipeImageID());
rb.add(rcp.getRecipeDescription());
rb.add(rcp.getRecipeLocations());
}
}
} else if (recipeID != null) {
for (Recipe rcp : recipesList) {
if (rcp.getRecipeID() == Integer.parseInt(recipeID)) {
rb = mxCur.newRow();
rb.add(rcp.getRecipeID());
rb.add(rcp.getRecipeCategory());
rb.add(rcp.getRecipeImageID());
rb.add(rcp.getRecipeDescription());
rb.add(rcp.getRecipeLocations());
}
}
} else {
for (Recipe rcp : recipesList) {
rb = mxCur.newRow();
rb.add(rcp.getRecipeID());
rb.add(rcp.getRecipeCategory());
rb.add(rcp.getRecipeImageID());
rb.add(rcp.getRecipeDescription());
rb.add(rcp.getRecipeLocations());
}
}
if (mxCur.getCount() == 0) {
rb = mxCur.newRow();
rb.add(0);
rb.add(0);
rb.add(R.drawable.air);
rb.add("No recipes found for this category");
rb.add(new int[] { 0,0,0,0,0,0,0,0,0 });
}
return mxCur;
}
But my view intent class is where I'm stuck
public class RecipeDetails extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.recipedetails);
Bundle extras = getIntent().getExtras();
String id = Integer.toString(extras.getInt("recipeID"));
ImageView imgResult = (ImageView) findViewById(R.id.imgResult);
int[] imgLocations = new int[9];
ImageView imgIngr1 = (ImageView) findViewById(R.id.imgIngr1);
ImageView imgIngr2 = (ImageView) findViewById(R.id.imgIngr2);
ImageView imgIngr3 = (ImageView) findViewById(R.id.imgIngr3);
ImageView imgIngr4 = (ImageView) findViewById(R.id.imgIngr4);
ImageView imgIngr5 = (ImageView) findViewById(R.id.imgIngr5);
ImageView imgIngr6 = (ImageView) findViewById(R.id.imgIngr6);
ImageView imgIngr7 = (ImageView) findViewById(R.id.imgIngr7);
ImageView imgIngr8 = (ImageView) findViewById(R.id.imgIngr8);
ImageView imgIngr9 = (ImageView) findViewById(R.id.imgIngr9);
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(RecipeProvider.CONTENT_URI, null, id, null, null);
if (cursor.moveToFirst()) {
imgResult.setImageResource(cursor.getInt(2));
setTitle(cursor.getString(3));
//________________HOW CAN I GET AN INT ARRAY OUT?_________________
int[] intLocations = cursor.getType(4); //Cannot convert int to int[]
int[] intUsedImages = cursor.getType(5); //Same here
imgIngr1.setImageResource(imgLocations[0]);
imgIngr2.setImageResource(imgLocations[1]);
imgIngr3.setImageResource(imgLocations[2]);
imgIngr4.setImageResource(imgLocations[3]);
imgIngr5.setImageResource(imgLocations[4]);
imgIngr6.setImageResource(imgLocations[5]);
imgIngr7.setImageResource(imgLocations[6]);
imgIngr8.setImageResource(imgLocations[7]);
imgIngr9.setImageResource(imgLocations[8]);
}
}
}
So basically eclipse tells me that it's getting an int but I know it's an int array.
What should I do?
