How to load an ImageView from a png file?
- by Peter vdL
I take a picture with the camera using
Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE );
startActivityForResult( intent, 22 );
When the activity completes, I write the bitmap picture out to a PNG file.
java.io.FileOutputStream out = openFileOutput("myfile.png", Context.MODE_PRIVATE);
bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
That goes OK, and I can see the file is created in my app private data space.
I'm having difficulty when I later want to display that image using an ImageView.
Can anyone suggest code to do this?
If I try to create a File with path separators in, it fails.
If I try to create a Uri from a name without separators, that fails.
I can open the file OK using:
java.io.FileInputStream in = openFileInput("myfile.png");
But that doesn't give me the Uri I need to set an image with
iv.setImageURI(u)
Summary: I have the picture in a png file in private app data. What's the code to set that into an ImageView?
Thanks.
