I have an ImageView. When you click on a ImageView, it will open gallery and you pick up a image and show it on ImageView. I have a condition that when I close my app and then I open it, the image will retain there . So for that, I am storing image Uri on sharedprefrence. And on opening the application i am retrieving the same Uri and tries to display the image on imageView.
However in some phones - image appears perfect like Mi(Lollipop), Samsung(KitKat) but it doesn't appear in phones like - Motorola(Marshmallow) ,One Plus One (Marshmallow). Any idea why it's happening ? Here is my code
For picking up an image i am using
Intent intent=new Intent();intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), Constants.SELECT_PICTURE);
And on OnActivityResult() code is
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==Constants.SELECT_PICTURE && resultCode==RESULT_OK && null!=data) {
Uri uri=data.getData();
Picasso.with(UsersProfileActivity.this)
.load(uri)
.centerCrop()
.resize(200,200)
.into(img_photo);
// This profile image i am storing into a sharedpreference
profile_image=uri.toString();
}
And while retrieving from sharedprefrence I convert String to uri by using Uri.parse(profile_image)
However if I notice, uri returns for different android phone is as follows
Mi(Lollipop)- Uri=content://media/external/images/media/12415
samsung(KitKat)-Uri=content://media/external/images/media/786
Motorola(Marshmallow)- Uri=content://com.android.providers.media.documents/document/image%3A30731
One Plus One (Marshmallow)- Uri=content://com.android.providers.media.documents/document/image%3A475
Hence when uri content is -content://media/external/images/media/ is display image on ImageView Perfect and in other cases it is not
Using clickable imagesYou can turn any View , such as an ImageView , into a button by adding the android:onClick attribute in the XML layout. The image for the ImageView must already be stored in the drawable folder of your project.
This example demonstrates how to load and display an image in ImageView on Android App. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main.xml. Step 3 − Add the following code to src/MyAndroidAppActivity.java
If you have the image size much larger than your chosen android device, or the image file size too, which could be larger than 10mb, the images won’t be previewed as android studio finds it difficult to load them thoroughly. So you’d better change the format and make the image size under 1mb.
1. id: id is an attribute used to uniquely identify a image view in android. Below is the example code in which we set the id of a image view. <ImageView android:id="@+id/simpleImageView" android:layout_width="fill_parent" android:layout_height="wrap_content" />
ImageView class or android.widget.ImageView inherits the android.view.View class which is the subclass of Kotlin. AnyClass.Application of ImageView is also in applying tints to an image in order to reuse a drawable resource and create overlays on background images. Moreover, ImageView is also used to control the size and movement of an image.
Try this
I developed and tested
and working on
In your MainActivity.java
add
profilePicture = (ImageView)findViewById(R.id.imgProfilePicture);
sharedPreferences = getSharedPreferences(getString(R.string.app_name)+"_ProfileDetails",MODE_PRIVATE);
// get uri from shared preference
String profilePicUri = sharedPreferences.getString("profilePicUrl","");
// if uri not found
if (profilePicUri.equalsIgnoreCase("")){
// code for open gallery to select image
Intent intent;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT){
intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
}else{
intent = new Intent(Intent.ACTION_GET_CONTENT);
}
intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), SELECT_PICTURE_CONSTANT);
}else{
try{
final int takeFlags = (Intent.FLAG_GRANT_READ_URI_PERMISSION
| Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
// Check for the freshest data.
getContentResolver().takePersistableUriPermission(Uri.parse(profilePicUri), takeFlags);
// convert uri to bitmap
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), Uri.parse(profilePicUri));
// set bitmap to imageview
profilePicture.setImageBitmap(bitmap);
}
catch (Exception e){
//handle exception
e.printStackTrace();
}
}
Now Handle onActivityResult
.
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == SELECT_PICTURE_CONSTANT && resultCode == RESULT_OK && null != data) {
Uri uri = data.getData();
// This profile image i am storing into a sharedpreference
SharedPreferences.Editor editor = sharedPreferences.edit();
// save uri to shared preference
editor.putString("profilePicUrl",uri.toString());
editor.commit();
profilePicture.setImageURI(uri);
}
}
In your Manifest
file add permission
<uses-permission android:name="android.permission.MANAGE_DOCUMENTS"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
Note:
Assuming
you added code for take permission
for Marshmallow
Result Uri
