Android:Problem in passing image and its URI between two activities

问题

Can we pass image and an image URI to other activity in same application using bundle?suggest me some way to do that?

USAGE :actually i have made an activity that crop an image taken from camera or from image stored in SD card depends upon the user. and another app that uses a background image and a border image both are overlay so as to see PHOTOFRAME.

So now I want to combine both app so that the cropped image come from first app should become the background image for the second app.ie comes in photoframe.How can i do that?

回答1:

Once you save your image in SD card

use this to cal the other activity.

final Intent intent = new Intent(MyClass.this, TargetClass.class);
final String root = Environment.getExternalStorageDirectory().getAbsolutePath();
intent.setData(Uri.parse(root + "/my/image/path/image.png"));
startActivity(intent);

if you are the reciever then you can get the path by calling

Uri path = getIntent().getData();

in the onCreate of the recieving activity. this is the standard way of checking for path by other activities.

Yes you can pass URI object,see putParcelable method in http://developer.android.com/reference/android/os/Bundle.html, URI already implements Parcelable interface,you can use corresponding get methods to get it.If any object that implements Parcelable interface then we can pass it using Bundle.
