First, define a standard code to identify the Intent:

private static final int PICK_IMAGE = 11;

Second, call the 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 placing the code above, you need to overwrite the onActivityResult of his Activity, because this method will receive the image from 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 user selected content, first of all we test if it is really coming from your gallery call through the variable PICK_PHOTO, then we turn the InputStream received on a Bitmap, and of a Bitmap for a Drawable making it possible to use in your ImageView.
