I have making a tab based app. There are three tabs. One of the tab is used to camera. So when I press camera tab then it opens up camera activity so that I could take pictures. Until here it works fine. When I take picture then that picture is showed in ImageView. From here when I press any other tab and then I press camera tab then camera activity does not start. It keep shows me that previous image on ImageView. What I want is whenever user taps on camera tab then it should opens camera activity. How can I achieve this effect?
Here is my code. Below os oncreate method which is in camera activity. So when camera tab is pressed it opens this activity.
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.camera);
userFunctions = new UserFunctions();
globalUID = getIntent().getExtras().getString("globalUID");
Toast.makeText(getApplicationContext(), globalUID, Toast.LENGTH_LONG).show();
ivUserImage = (ImageView)findViewById(R.id.ivUserImage);
bUpload = (Button)findViewById(R.id.bUpload);
openCamera();
}
private void openCamera() {
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CameraResult);
}
Update
I did this but still the same problem
boolean flag = true;
#Override
protected void onResume() {
super.onResume();
//flag = true;
if(flag) {
openCamera();
flag = false;
}
}
Edit
After following Imran's answer my code looks like this now. I am also adding additional code. But this code still does not work.
public class Camera extends Activity {
ImageView ivUserImage;
Button bUpload;
Intent i;
int CameraResult = 0;
Bitmap bmp;
public String globalUID;
UserFunctions userFunctions;
String photoName;
InputStream is;
String largeImagePath;
int serverResponseCode = 0;
public static boolean flag = true;
#Override

// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.camera);
userFunctions = new UserFunctions();
globalUID = getIntent().getExtras().getString("globalUID");
//flag = getIntent().getExtras().getBoolean("flag");
Toast.makeText(getApplicationContext(), globalUID, Toast.LENGTH_LONG).show();
ivUserImage = (ImageView)findViewById(R.id.ivUserImage);
bUpload = (Button)findViewById(R.id.bUpload);
//openCamera();
if(flag ==true)
openCamera();
}
#Override
protected void onResume() {
super.onResume();
if(flag==true)
openCamera();
}
private void openCamera() {
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CameraResult);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
flag = false;
if(resultCode == RESULT_OK) {
//set image taken from camera on ImageView
Bundle extras = data.getExtras();
bmp = (Bitmap) extras.get("data");
ivUserImage.setImageBitmap(bmp);
//Create new Cursor to obtain the file Path for the large image
String[] largeFileProjection = {
MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATA
};
String largeFileSort = MediaStore.Images.ImageColumns._ID + " DESC";
Cursor myCursor = this.managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, largeFileProjection, null, null, largeFileSort);
try {
myCursor.moveToFirst();
//This will actually give you the file path location of the image.
largeImagePath = myCursor.getString(myCursor.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
File f = new File("" + largeImagePath);
photoName = f.getName();
bUpload.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
new Upload().execute(largeImagePath, globalUID, photoName);
}
});
} finally {
myCursor.close();
}
}
}
}
Here is my tab activity code
public class DashboardActivity extends TabActivity {
UserFunctions userFunctions;
public String globalUID;
DatabaseHandler db;
boolean flag = true;
#Override

// TODO Auto-generated method stub
super.onCreate(savedInstanceState);

db = new DatabaseHandler(getApplicationContext());
// Check login status in database
userFunctions = new UserFunctions();
if(userFunctions.isUserLoggedIn(getApplicationContext())){
//globalUID = getIntent().getExtras().getString("globalUID");
HashMap<String, String> data = db.getUserDetails();
globalUID = data.get("uid");
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
//Home
intent = new Intent(this, Home.class);
intent.putExtra("globalUID", globalUID);
spec = tabHost.newTabSpec("home").setIndicator("", res.getDrawable(R.drawable.home_icon)).setContent(intent);
tabHost.addTab(spec);
//Camera

} else {

This is because when you are switching between tabs your activity doesnt call onCreate again.
Try moving call to openCamera(); into onResume method and it should be fine.
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.camera);
userFunctions = new UserFunctions();
globalUID = getIntent().getExtras().getString("globalUID");
Toast.makeText(getApplicationContext(), globalUID, Toast.LENGTH_LONG).show();
ivUserImage = (ImageView)findViewById(R.id.ivUserImage);
bUpload = (Button)findViewById(R.id.bUpload);
}
protectd void onResume(){
super.onResume();
openCamera();
}
private void openCamera() {
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, CameraResult);
}
Each Activity in an TabHost calls onCreate() only once for reason of efficiency. This is why the openCamera() doesn't get called again and again.
In order to handle this, you can in the parent Activity to implement and register an OnTabChangeListener, where you can catch which tab is clicked and perform any desired action.
Hope this helps!
add onResume() in your activity and call openCamera(); from onResume() also as:
public static boolean flag = true;
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.camera);
userFunctions = new UserFunctions();
globalUID = getIntent().getExtras().getString("globalUID");
Toast.makeText(getApplicationContext(), globalUID, Toast.LENGTH_LONG).show();
ivUserImage = (ImageView)findViewById(R.id.ivUserImage);
bUpload = (Button)findViewById(R.id.bUpload);
if(flag ==true)
openCamera();
}
#Override
protected void onResume() {
super.onResume();
if(flag==true)
openCamera();
}
and in on onActivityResut()
flag =false;
or on tabclick
YourflagActivity.flag=true;

I'm very new to this coding thing and I hope that anyone of you can help me out on this. Basically I have three different buttons with different image view and I would like to upload them to my MySQL. However when I press all three button at different times, it will only affect the 1 of the image views. Appreciate if you could help.

I think you should change request codes for each gallery intent on each button click.
btnuploadvl.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(gallery, "request code for btnuploadvl");
}
});
btnuploaddl.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(gallery, "request code for btnuploaddl");
}
});
btnupadloadnric.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(gallery, "request code for btnupadloadnric");
}
});
And then check request code detecting which button is clicked on onActivityResult.
In my activity I am able to upload a picture from the gallery.
I would like to check if the user has indeed uploaded the picture prior to hitting confirm. One way of achieving this, I want to check if the upload picture button has been clicked.
I also want to see if an edittext has been filled through the following code but is struggling with image:
String name = mName.getText().toString();
// Number age = mAge.getText(;
String headline = mHeadline.getText().toString();
// age = ((String) age).trim();
name = name.trim();
headline = headline.trim();
if (name.isEmpty() || headline.isEmpty()) {
AlertDialog.Builder builder = new AlertDialog.Builder(ProfileCreation.this);
builder.setMessage(R.string.signup_error_message)
.setTitle(R.string.signup_error_title)
.setPositiveButton(android.R.string.ok, null);
AlertDialog dialog = builder.create();
dialog.show();
}
else {
// create the new user!
below is how the image is being selected:
Button buttonLoadImage = (Button) findViewById(R.id.btnPictureSelect);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(

startActivityForResult(i, RESULT_LOAD_IMAGE);

String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();

imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}

}
You can set a boolean to true, if image is selected by user in onActivityResult
//global variable
boolean imagePicked = false;
//In onActivityResult change its value
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
&& null != data) {
imagePicked = true;
//other things
}
else {
imagePicked = false;
//other things
}
In last button click check imagePicked is true or false and proceed accordingly.
Hope it helps.
I have successfully been able to store user entered information into parse, but I haven't figure out how to do store a user uploaded image that would be associated with the current user in parse, and to retrieve a user image at a later time.
To clarify this, below is the code I have used for my profile creation activity, an activity that is prompted after the user has signing using social media and responds to a series of questions like age, preferred name, and where those information are later updated in the parse database and added to the current user.
Also in the activity, the user is already able to upload a picture from their device, my issue now resolves around taking that uploaded picture and storing it on parse, and associating the image with the current user who has signing using their social media account - the social media integration is done through parse.
I have looked into the following guide, but is still greatly confused.

Any assistance would be greatly appreciated.
Thanks in advance.

Also in the activity, the user is already able to upload a picture
from their device, my issue now resolves around taking that uploaded
picture and storing it on parse, and associating the image with the
current user who has signing using their social media account - the
social media integration is done through parse.
Read the docs on files and on the response type when a file is upload to parse.com
"media":{"__type":"File","name":"e580f231-...-picf1","url":"http://files.parse.com/..52d6-picf1"}
So, after POST on the file to parse, you have a logical FILE entity that you can then point to in another class.
In that other clase , you can also point to the user who created the FILE.
Class2 {"createdby" : pointer($user), "media" : pointer($file)}
With that, you have a separate class with 2 , pointer types ( toUser, toFile ) and the col headers on the data browser will show :
pointer<_User> for the user
file for the file
I have successfully been able to store user entered information into parse, but I have been having difficulty storing images into to parse, to be able to retrieve at a later date.
To clarify this, below is the code I have used for my profile creation activity, an activity that is prompted after the user has signing using social media and responds to a series of questions like age, preferred name, and where those information are later updated in the parse database and added to the current user.

You need to wait for the file to finish saving before you add it to the user.
Try adding a completion block to your file.saveInBackground() call, and moving all the currentUser manipulation into that completion block.
I'm currently working on an android app with web services, using an external database. The app consists of several tasks and each task is assigned to each camera id. Each camera have specific long/lat stored in the database. So right now when I select a specific task, there would be a guide button showing the user current location as a marker in the google map. I want to display the long/lat of the task as a marker on the google map, so there would be 2 marker. Just need some help with the android coding. Any help would be appreciated!
