I'm developing an APP where it's possible to create an account, so I want to know how to do when clicking on ImageView, open the gallery of the smartphone, and when clicking on an image, the src of the ImagrView was changed to the photo that the user selected.
Thank you in advance !!
First, set a default code to identify Intent :
private static final int PICK_IMAGE = 11;
Second, call Intent who will be responsible for presenting the user which application he wants to open the gallery to choose the image:
Intent getIntent = new Intent(Intent.ACTION_GET_CONTENT);
getIntent.setType("image/*");
Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
pickIntent.setType("image/*");
Intent chooserIntent = Intent.createChooser(getIntent, "Select Image");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] {pickIntent});
startActivityForResult(chooserIntent, PICK_IMAGE);
After putting the above code, you need to overwrite the onActivityResult of your Activity , because this method will receive the image of the gallery:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_PHOTO && resultCode == Activity.RESULT_OK) {
if (data == null) {
// Nenhuma imagem selecionada...
return;
}
InputStream inputStream = context.getContentResolver().openInputStream(data.getData());
Bitmap b = BitmapFactory.decodeStream(inputStream);
Drawable d = new BitmapDrawable(b);
suaImageView.setImageDrawable(d);
}
}
In the above code we receive the content selected by the user, first of all we test if it is really coming from your gallery call through the variable PICK_PHOTO , then we transform the InputStream received into a Bitmap , and a Bitmap to Drawable making it possible to use in your ImageView .
