Updating the profile picture of a user

Updating the profile picture of a user - android

I am making an application where I am using ImageLoading Framework for downloading the images from the server and put the URLs in the cache. Now I want the user's profile picture updating but even after updation of the profile pic on the sever it's not displaying in the application.
The app is showing the old profile pic of the User. Why this problem is arising and how can I troubleshoot?
Code for update onclick:
update_profile_pic.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
String value_for_test="delete";
Toast.makeText(getBaseContext(), "it works", Toast.LENGTH_SHORT).show();
Intent i=new Intent(getApplicationContext(),ProfilePictureCaptureHomeActivity.class);
i.putExtra("image",value_for_test);
startActivity(i);
Profile Pic CaptureHome
DBAdapter db = new DBAdapter(getApplicationContext());
db.open();
if (null == phoneNumber)
{
Cursor c = db.getUserInfo();
phoneNumber = c.getString(0);
imageUrl = c.getString(1);
System.out.println("the imageUrl is"+imageUrl);
c.close();
}
setContentView(R.layout.profilepic_capture);
if (null == imageUrl)
{
Cursor imageUrlObj = db.getUserInfo();
imageUrl = imageUrlObj.getString(1);
System.out.println("the imageurl is"+imageUrl);
imageUrlObj.close();
}
db.close();
for updating the profile picture:
if(image!=null){
Toast.makeText(getApplicationContext(), "Redirected", Toast.LENGTH_LONG).show();
imageUrl=null;
}
if(imageUrl != null)
{
Intent uploadimg = new Intent(ProfilePictureCaptureHomeActivity.this,ListeningAndSharingHomeActivity.class);
uploadimg.putExtra("phoneNumber", phoneNumber);
startActivity(uploadimg);
}
else
{
Log.v("ProfilePictureCaptureHomeActivity", "Staying Here");
}
_gallerybutton = (ImageButton) findViewById(R.id.btn_gallery);
_photobutton = (ImageButton) findViewById(R.id.btn_photo);
System.out.println("here in popup phoneeeeee" + phoneNumber);
System.out.println("here in flag************" + firstUpload);
_gallerybutton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
System.out.println("here in galleryyyyyyyyyy");
Intent uploadimg = new Intent(ProfilePictureCaptureHomeActivity.this,ProfilePicFromGallery.class);
uploadimg.putExtra("phoneNumber", phoneNumber);
startActivity(uploadimg);
}
});
_photobutton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
System.out.println("here in take piccccc");
Intent capIntent = new Intent(ProfilePictureCaptureHomeActivity.this,ProfilePicFromCamera.class);
startActivity(capIntent);
}
});

have a look at this code.
private String deleteExistingFile(String url , Context context)
{
String SaveFolderName = context.getFilesDir().getAbsolutePath() + "/yourinternalmemoryfolder";
String str_randomnumber= url.substring(url.lastIndexOf("/") + 1);
File wallpaperDirectory = new File(SaveFolderName);
if (!wallpaperDirectory.exists())
wallpaperDirectory.mkdirs();
String Photo_ImagePath=SaveFolderName+"/" + str_randomnumber ;
String result = "";
System.out.println("file path to be deleted " + Photo_ImagePath);
File f = new File(Photo_ImagePath);
if (f.exists())
{
System.out.println(" EEEEEEEEEEXXXXXXXXIIIIISSSSSSSTTTTTTT ");
try {
if(f.delete() == true){
result = "Success";
}else{
result = "Failure";
}
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
return "Error";
}
}
System.out.println("deleting existing file " + result);
return result;
}

Android Toast did not show after open Gallery and pick image

I want to show Toast (or progress bar) when clicking on the button "btnSearchImg". If before upload image, button clicked say "first pick image from gallary" and if after upload image clicked say "waiting". the toast before uploading image work fine but after uploading didn't work fine! my entire Activity code:
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_by_image);
Toasty.Config.getInstance().setTextSize(15).apply();
mSharedPreferences = getSharedPreferences("PREFERENCE", Context.MODE_PRIVATE);

Thread t = new Thread(runner, "Code Executer");

}
}
If I put the "Waiting..." Toast after the FindSimilarRequestedImage() the toast will show up, but I need the toast show immediately after clicking on the btnSearchImg.
NOTE: Also in the dateiLesenStringBuilder() I removed the thread t that this part of code runs in normal flow and serial, but nothing changes!

Instead of toast use logcat to see if they run sequentially or not, maybe toast takes time to run

I solved this problem by putting the part of code in delay like below:
private void FindSimilarRequestedImage() {
if (ivGalleryImgLoad.getDrawable() != null) {
pbImgRetrvialProccess.setVisibility(View.VISIBLE);
Toasty.success(getBaseContext(), "Waiting ...", Toast.LENGTH_LONG).show();
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
File loadedImageFilePath = new File(getRealPathFromURI(selectedImageUri));
queryFeatureX = uniformQuantization(loadedImageFilePath);
dateiLesenStringBuilder();
}
}, 5000);
} else {
Toasty.error(getBaseContext(), "first pick image from gallary", Toast.LENGTH_LONG).show();
}
}
Now before destroying activity throw functions, I first show the toast, then run other functions!

Use one ViewHolder and define three fields and show hide views according status.
Maintain Status in list not in adapter.
Because list item recreated on list view scroll.

You can see same thumbnail in multiple list items as Android reuses the view of list item.
Care needs to be taken that you make the thumbnail invisible or use 'Icon which suggests no image' if you don't have the correct image for that position of list item. This check has to be made in getView method of your adapter of the list.

Android hide images only from gallery

I have created an application where one can view images. The problem I am facing is that when I use ".nomedia" in folder it hides images from gallery and images are also hidden in my application. I need a method with help of which images can remain hidden from gallery but shown in my application. I am accessing images using path of folder.
Code:
public class SdActivity extends Activity implements
MediaScannerConnectionClient {
public String[] allFiles;
private String SCAN_PATH;
private static final String FILE_TYPE = "*/*";
private MediaScannerConnection conn;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
File folder = new File("/sdcard/DCIM");
allFiles = folder.list();
// uriAllFiles= new Uri[allFiles.length];
for (int i = 0; i < allFiles.length; i++) {
Log.d("all file path" + i, allFiles[i] + allFiles.length);
}
// Uri uri= Uri.fromFile(new
// File(Environment.getExternalStorageDirectory().toString()+"/yourfoldername/"+allFiles[0]));
SCAN_PATH = Environment.getExternalStorageDirectory().toString()
+ "/yourfoldername/" + allFiles[0];
Log.d("SCAN PATH", "Scan Path " + SCAN_PATH);
Button scanBtn = (Button) findViewById(R.id.buttonLoadPicture);
scanBtn.setOnClickListener(new OnClickListener() {
#Override

// TODO Auto-generated method stub
startScan();
}
});
}

}
conn = new MediaScannerConnection(this, this);
conn.connect();

how to make a view visible from customAdapter's textView's ClickEvent in android?

I have made an activity In that I am having three relative Layouts and i am making them visible and gone as per needed.Now I have one ListView Called BuyingRequestList and for that i have made customeAdapter ,Now I have put a clickEvent of CustomAdapter's textView,Now what i need is when I click on the ListItem's textView "Quote" one relative layout "quote_view" is only visible and other two layouts should be invisible,My code is as below:
BuyingRequest.java

Create an interface class, say ViewHider
public interface ViewHider{
public void hideView(String clickedtext);
}
have your activity implement this.
In your activity add unimplemented method and write inside it like
#Override
public void hideView(String clickedtext) {
if(clickedtext.equals("Quote"){
layoutName.setVisibility(View.GONE);
}
}
In your adapter, create an object of ViewHider class
ViewHider viewHider;
then, set click listener for the text view you want and inside that call the method
if(textView.getText.equals("Quote")
viewHider.hideView("Quote");

Use
listView.invalidate();
after you have made changes to the list
Eg. you have added/removed/updated data in listView.

Just an idea:
Call your code public CategoryListAdapter1 adapter; as global to class.
Use adapter.notifyDataSetChanged(); whenever your list going to refresh.
