I have a activity with a couple of ImageViews. The user can LongPress an ImageView and they have the option of getting any image from the camera gallery. I am trying to save the imagepath of those images so that when the user closes and opens the app again the image will still be in the imageView. I dont understand why this isn't working.
Here is my Activity A where the imageView is
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
im1.setImageURI(selectedImageUri);}}}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);};
#Override
protected void onPause() {
SharedPreferences sp = getSharedPreferences("AppSharedPref", 1); // Open SharedPreferences with name AppSharedPref
Editor editor = sp.edit();
editor.putString("ImagePath", selectedImagePath); // Store selectedImagePath with key "ImagePath". This key will be then used to retrieve data.
editor.commit();
super.onPause();
}
protected void onResume1() {
SharedPreferences sp = getSharedPreferences("AppSharedPref", 1);
selectedImagePath = sp.getString("ImagePath", "");
super.onResume();
}
And Activity B gets the cam gallery pic and sends back to Activity A
Button send = (Button) findViewById(R.id.send);
send.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent=new Intent();
setResult(RESULT_OK, intent);
Bundle bundle=new Bundle();
bundle.putInt("image",R.id.showImg);
intent.putExtras(bundle);
finish(); }
});
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}}}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
Make:
#Override
protected void onResume() {
SharedPreferences sp = getSharedPreferences("AppSharedPref", 1);
selectedImagePath = sp.getString("ImagePath", "");
Bitmap myBitmap = BitmapFactory.decodeFile(selectedImagePath);
im1.setImageBitmap(myBitmap);
super.onResume();
}
instead of:
protected void onResume1() {
SharedPreferences sp = getSharedPreferences("AppSharedPref", 1);
selectedImagePath = sp.getString("ImagePath", "");
super.onResume();
}
Because your activity extends Activity class, which has this method declared and implemented. This method is called after Activity returns to foreground. What you want is to override this method so that it does what you want it to do.

I want to pick only those images from gallery which are clicked from camera,not present from other sources.
Cursor imagecursor = getApplicationContext().getContentResolver().query(
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
new String[] {MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID}, null,
null, null);
This query gives me all the images.
I want the path to camera images irrespectice of gallery and camera intent.Is there some generic method which returns the path of captured images path
here is an example hope it help!!
package com.mahesh.gallerytestapp;
public class MainActivity extends Activity {
Uri selectedImageUri;
String selectedPath;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b = (Button) findViewById(R.id.bGallery);
Button bCam= (Button) findViewById(R.id.bCamera);
ImageView preview = findViewById(R.id.preview);
bCam.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 100);
}
});
b.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
openGallery(10);
}
});
}
public void openGallery(int req_code){
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select file to upload "), req_code);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if(data.getData() != null){
selectedImageUri = data.getData();
}else{
Log.d("selectedPath1 : ","Came here its null !");
Toast.makeText(getApplicationContext(), "failed to get Image!", 500).show();
}
if (requestCode == 100 && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
selectedPath = getPath(selectedImageUri);
preview.setImageURI(selectedImageUri);
Log.d("selectedPath1 : " ,selectedPath);
}
if (requestCode == 10)
{
selectedPath = getPath(selectedImageUri);
preview.setImageURI(selectedImageUri);
Log.d("selectedPath1 : " ,selectedPath);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}
I am working on app for editing photos.
I have a button in first activity and ImageView in second activity. When I click the button it would open gallery and I would be able to select an image. The selected image needs to appear in my ImageView in second activity but it doesn't. For time being i am displaying image in first activity it self but can anyone suggest me how to display that image in next activity.
Below is my code.
public class Camera_Gallery_Option extends Activity {
private static final int CAMERA_REQUEST = 1888;
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.camera_gallery_option);
Button galleryButton= (Button) findViewById(R.id.button1);
galleryButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"),
SELECT_PICTURE);
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
imageview.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
Pass the selectedImageUri to the second activity and set the uri to image view in the second activity ?
startActivity(new Intent(this, SecondActivity.class).setData(selectedImageUri));
In the SecondActivity:
protected void onCreate(Bundle savedInstanceState) {
...
imageView.setImageURI(getIntent().getData());
}
I have some code that get's a pic from the camera gallery. It works fine when you use a button from an activity to get pic and put pic on that activity but I cant get it to my Imageview when I try this with a button on AlertDialog. Any help?
This code by itself is fine
((Button)dialogView.findViewById(R.id.button3))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"),SELECT_PICTURE);}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
im1.setImageURI(selectedImageUri);}}}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);}});
But when you add this code to AlertDialog it wont function anymore
lay1.setOnLongClickListener(new OnLongClickListener() {
public boolean onLongClick(View v) {
LayoutInflater myLayout = LayoutInflater.from(context);
final View dialogView = myLayout.inflate(R.layout.alerthelp, null);
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
alertDialogBuilder.setView(dialogView);
final AlertDialog alertDialog = alertDialogBuilder.create();
((Button) dialogView.findViewById(R.id.button3))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
im1.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
});
alertDialog.show();
return true;
}
});
I have tested the code on another activity from a Button and it works fine but when I open alertDialog to do it, I cant get the pic back to my imageview. I can still get to my Gallery and click on a pic but when I try to save it it wont put the pic in the imageView.
Try moving the method onActivityResult outside the click listener alongside your other activity methods, like so
public class MyActivity extends Activity {
// other methods and fields
private ImageView im1;
// initialize im1 in your onCreate() method
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
im1.setImageURI(selectedImageUri);
}
}
}
}
I have an activity that opens another activity to get a camera gallery pic. The picture comes back to my original activity and rest in an imageView. That's working fine. How do I save the image so when the user comes back later, or kills to app the image is still there. I know I am supposed the use Shared Preferences to get the image path and not save the image itself but I just don't know how do that.
Activity A
private ImageView im1;
private String selectedImagePath;
private static final int SELECT_PICTURE = 1;
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
im1.setImageURI(selectedImageUri);
}}}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
};
((Button)dialogView.findViewById(R.id.button3))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}});
Activity B
Button send = (Button) findViewById(R.id.send);
send.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent=new Intent();
setResult(RESULT_OK, intent);
Bundle bundle=new Bundle();
bundle.putInt("image",R.id.showImg);
intent.putExtras(bundle);
finish();
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}}}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
Override onPause() method in Activity with an image (to understand why onPause, check life cycle of an Activity diagram here: http://developer.android.com/reference/android/app/Activity.html) like this:
#Override
protected void onPause() {
SharedPrefrences sp = getSharedPreferences("AppSharedPref", 0); // Open SharedPreferences with name AppSharedPref
Editor editor = sp.edit();
editor.putString("ImagePath", selectedImagePath); // Store selectedImagePath with key "ImagePath". This key will be then used to retrieve data.
editor.commit();
super.onPause();
}
It means that whenever this Activity goes into background, the image path will be saved in SharedPreferences with name AppSharedPref - this name can be whatever you like, but you need to use the same one when retrieving data.
Then override onResume() method in the same Activity so that you can retrieve image path when Activity comes to foreground:
#Override
protected void onResume() {
SharedPreferences sp = getSharedPreferences("AppSharedPref", 0);
selectedImagePath = settings.getString("ImagePath", "");
super.onResume();
}
You may also want to play with overriding other methods, like for example onStart() according to diagram, but this I leave to you.
You could use the "selectedImagePath" in passing intents from one Activity to another.
in Activity A.
Intent intent = new Intent(this , Activity.class);
intent.putExtra("imagePath", selectedImagePath );
and to get it in Activity B,
String strImagePath = getIntent().getExtras().getString("imagePath");
String imagePath = ... ;
SharedPrefrences prefs = getSharedPreferences("application_settings", 0);
Editor editor = prefs.edit();
editor.putString("image_path", imagePath);
editor.commit();
SharedPreferences prefs = this.getSharedPreferences(
"com.example.app", Context.MODE_PRIVATE);
To read preferences:
String path = prefs.getString("key", default value);
To edit and save preferences
prefs.edit().putString("key", value).commit();
Whenever I try to click on the browse button , I want to browse my gallery and select a photo from it and display it in a new activity.
Until I displayed the photo on the same activity there was no error , but as soon I change the code to transfer the photo on another intent there is a force close error
Here is my code:
Main screen :
Button button = (Button) findViewById(R.id.Button01);
button.setOnClickListener(new OnClickListener()
{
public void onClick(View arg0)
{
Intent intent1 = new Intent(MainActivity.this,Edit.class);
startActivity(intent1);
}
});
Another screen :
public class Edit extends Activity
{
private String selectedImagePath;
private static final int SELECT_PICTURE = 1;
private ImageView img;
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.edit);
img = (ImageView)findViewById(R.id.ImageView1);
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK)
{
if (requestCode == SELECT_PICTURE)
{
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
