如何从内置图库中检索picasa照片？

Question

我想从内置的Android图库中检索调用ACTION_PICKIntent 的照片.我对Picasa的图片有疑问.我已将代码用于此链接,但它不起作用(File对象不存在).请问任何想法.

Answer 1

ACTIVITYRESULT_CHOOSEPICTURE是调用startActivity时使用的int(intent,requestCode);

public void onActivityResult(int requestCode, int resultCode, Intent data) {
  if(requestCode == ACTIVITYRESULT_CHOOSEPICTURE) {
    BitmapFactory.Options options = new BitmapFactory.Options();
    final InputStream is = context.getContentResolver().openInputStream(intent.getData());
    final Bitmap bitmap = BitmapFactory.decodeStream(is, null, options);
    is.close();
  }
}

Answer 2

如果插入此指令，则代码有效：

 intent.putExtra("crop", "true");
