Question

I have an application that allow users to choose picture from native gallery then I show this image in image view widget.

My question is:
1-i have to send this image to another Activity. How can i do it.

2-in the receiver Activity i should show it in image view widget as in image not link or Something

I tried this code but it gives me a RunTime Error

   Bitmap image = Bitmap.createBitmap(view.getWidth(), view.getHeight(),Bitmap.Config.RGB_565);
   view.draw(new Canvas(image));
   String url = Images.Media.insertImage(getContentResolver(), image,"title", null);

Answer 1

Just follow the below steps…

Uri uri = null;
1) on any click event use the below code to open native gallery

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"),0);

This will open gallery select picture will return you to your activity. OnActivity result.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case 0:
    if (resultCode == RESULT_OK) {
    try {
    uri = Uri.parse(data.getDataString());
    imageView.setImageUri(uri);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
    e.printStackTrace();
    }}
    break;
    }
}

2) Also instead of passing the image you can pass the URI to next activity as you pass string and inthe secont activity you get it using intent.

Intent i = new Intent(this, Second.class);
i.putExtra("URI", uri.toString() );
startActivity(i);

and in the second activity

String uri = getIntent().getStringExtra("URI");

Now you have string just set it to the image view like below

imageView.setImageUri(Uri.parse(uri));
