I want to choose a pdf file on a button click and send that file to a url on another buttonclick. My issue is with selecting the pdf file. I am getting null in "onActivityResult()" method.
My code is
SelectButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent();
intent.setType("application/pdf");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Pdf"), PDF_REQ_CODE);
}
});
ActivityResult method is
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PDF_REQ_CODE && resultCode == RESULT_OK && data != null && data.getData() != null) {
uri = data.getData();;
SelectButton.setText("PDF is Selected");
}
}
But I am getting uri as null and getting null pointer exception when trying to get file path from uri.
Try this and tell me!
Button button = (Button) x.findViewById(R.id.buttonStripText);
button.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent,PICKFILE_RESULT_CODE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
switch(requestCode){
case PICKFILE_RESULT_CODE:
if(resultCode==RESULT_OK){
fileName = data.getData().getPath();
}
break;
}
}

I am wondering if using a Chooser means you can't send extra custom data to the receiving intent?
I call a file selection intent like this
public static void receiveFiles(final AppCompatActivity activity, int which) {
Intent receiveIntent = new Intent(Intent.ACTION_GET_CONTENT);
receiveIntent.setType("text/comma-separated-values");
String[] mimetypes = {"text/csv", "text/comma-separated-values", "application/csv"};
receiveIntent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
receiveIntent.addCategory(Intent.CATEGORY_OPENABLE);
receiveIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, false);
receiveIntent.putExtra(IMPORT_OPTION_WHICH, which); //this line
activity.startActivityForResult(Intent.createChooser(receiveIntent, "Pick CSV"), REQUEST_IMPORT_CSV);
}
But then in onActivityResult after the user selects a file:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case REQUEST_IMPORT_CSV:
if (data != null) {
Uri uri = data.getData(); //is correct
int which = data.getIntExtra(IMPORT_OPTION_WHICH, -1);
//but this always -1!
}
break;
}
}
}
How can I get it to correctly extract the value I passed into the intent?
public class Profile extends Fragment implements Profile_frg{
imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
final Dialog d = new Dialog(mainActivity);
d.requestWindowFeature(Window.FEATURE_NO_TITLE);
d.setContentView(R.layout.activity_custom_dialog);
d.setCanceledOnTouchOutside(true);
gallery = (ImageView) d.findViewById(R.id.imageView1);
camera = (ImageView) d.findViewById(R.id.imageView2);
cancel = (ImageView) d.findViewById(R.id.imageView3);
cancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub

}
});
gallery.setOnClickListener(new OnClickListener() {
#Override

try {
Intent gintent = new Intent();
gintent.setType("image/*");
gintent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(
gintent, "Select Picture"), PICK_IMAGE);
} catch (Exception e) {
Toast.makeText(mainActivity,
e.getMessage(), Toast.LENGTH_LONG).show();
Log.e(e.getClass().getName(), e.getMessage(), e);
}
d.dismiss();
}
});
camera.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// define the file-name to save photo taken by Camera
// activity
String fileName = "new-photo-name.jpg";
// create parameters for Intent with filename
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION,
"Image captured by camera");
// imageUri is the current activity attribute, define
// and save it for later usage (also in
// onSaveInstanceState)
imageUri = context.getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
values);
// create new Intent
Intent intent = new Intent(
MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, PICK_Camera_IMAGE);
d.dismiss();
}
});
d.show();
}
});
}// Work Fine till here...
public void onActivityResult(int requestCode,int resultCode,Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
}//didn't detect this method
Yes, there is no onActivityResult() callback in fragments.
You have to override activityResult method in your host activity(in which your fragment is defined)
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == GALLERY/CAMERA_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
Fragment yourFragment = getSupportFragmentManager().findFragmentByTag("FRAGMENT_TAG"); // same tag while adding fragment for the first time.
if (yourFragment != null) {
yourFragment.onActivityResult(requestCode, resultCode, data); //calling method that should be defined in your fragment.
}
}
super.onActivityResult(requestCode, resultCode, data);
}
And in your fragment do like this :
public void onActivityResult(int requestCode,int resultCode,Intent data) {
...
Pull your image data from data object
do your further process from here.
...
}
Yes, startActivityForResult will not work directly if you are calling it from any fragment. After getting the result, the callback will hit the onActivityResult of the Hosting Activity from where you have to manually redirect it to the respective fragment.
Below is the sample code of the onActivityResult of your Activity. Please note that this only redirect the result to the respective fragment.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case 1001:
Fragment frag = getSupportFragmentManager().findFragmentByTag("TAG"); // TAG should be same as the one you entered while adding the fragment
if (frag != null) {
frag .onActivityResult(requestCode, resultCode, data);
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
I read an text input from the user, this input i use it as a name of a picture i'm taking by the camera.
i store this name and the path of the image name into Sqlite Database.
what I'm trying to do is, after clicking OK to accept the taken picture, i want the saved path to be displayed in a toast.
the problem is, when I click OK to accept the picture, nothing is being displayed and i cant switch from the camera activity to the activity that called the camera activity"the previous activity"
Note: I'm using the emulator not a real device.
OnClickListener btn_TakePictureListener = new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
String imgPath = retrievePath();
intent.putExtra(MediaStore.EXTRA_OUTPUT, getImageUri(imgPath));
startActivityForResult(intent, RequestCode);
}
};
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RequestCode && resultCode == RESULT_OK) {
String s = data.getData().toString();
Toast.makeText(getBaseContext(), ""+s, Toast.LENGTH_SHORT).show();
}
}
if you are passing Uri for you image then you can retrieve image as taken by camera:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(
Environment.getExternalStorageDirectory(), "temp.jpg")));
startActivityForResult(intent, 1);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == NONE)
return;
if (requestCode == 1) {
// Set the file save path with directory
File picture = new File(Environment.getExternalStorageDirectory()
+ "/temp.jpg");
Uri imageuri= Uri.fromFile(picture);
//set to imageview here
}
}
EDIT:
For Getting data uri in onActivityResult start Camra Activiyt as:
Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,IMAGE_UNSPECIFIED);
startActivityForResult(intent, 2);
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == NONE)
return;
if (requestCode == 1) {
Uri uriimg = data.getData();
Toast.makeText(getBaseContext(), ""+uriimg.toString(), Toast.LENGTH_SHORT).show();
}
}
