我已阅读此链接：在打开图像的Andr​​oid内置的图库应用程序编程Open在Android中内置的应用程序库的图像编程的，而code看起来很好。

这结果与下面的图片： http://i.stack.imgur.com/vz3S8。 png格式，但是这不是我想要的结果。

我想打开类似于画廊： http://i.stack.imgur.com /ZoUvU.png 。我想选择的图片形成的文件夹画廊。

你知道如何修改code？

我用：

 意向意图=新的Intent（）;intent.setComponent（新单元名（com.android.gallery，com.android.camera.GalleryPicker））;// intent.setType（图像/ *）;intent.setAction（Intent.ACTION_GET_CONTENT）;Log.i（AA，adafdsfa）;startActivityForResult（意向，1）; 

通过我得到的文件夹，画廊，但我不能让图片的路径。

 文件DIR =新的文件（Environment.getExternalStorageDirectory（）的toString（）+/ SD卡/ yourfolder）;        Log.d（文件路径，dir.getPath（））;        串dirPath = dir.getAbsolutePath（）;        如果（dir.exists（）及＆放大器; dir.isDirectory（））{            意向意图=新意图（Intent.ACTION_VIEW）;            //告诉你的意图，以获得内容            //打开URI对你的SD卡图像目录                            //其高达你想要的数据图像或视频。            intent.setType（图像/ *）;        // intent.setType（视频/ *）;            intent.setData（Uri.fromFile（DIR））;        // intent.setType（媒体/ *）;        //意图。            startActivityForResult（意向，1）;        }        其他        {            showToast（无文件存在，以示）;        }      保护无效的onActivityResult（INT申请code，INT结果code，意图数据）{    // TODO自动生成方法存根    super.onActivityResult（要求code，结果code，数据）;     如果（要求code == 1）{         如果（数据== NULL）{            showToast（无图像中选择）;            //完（）;        }         其他         {         乌里selectedImageUri = data.getData（）;      //串filemanagerstring = selectedImageUri.getPath（）;         //媒体库       字符串selectedImagePath =的getPath（selectedImageUri）;         如果（selectedImagePath！= NULL）         {             意向意图=新的Intent（）;             intent.setAction（Intent.ACTION_VIEW）;             intent.setData（selectedImageUri）;             startActivity（意向）;         }         其他         {             showToast（映像路径不正确）;         }     }        }} 

I have read this link :Open an image in Android's built-in Gallery app programmatically Open an image in Android's built-in Gallery app programmatically, and the code looks well.

It results with following image: http://i.stack.imgur.com/vz3S8.png, but this is not the result I want.

I want to open the gallery similar to: http://i.stack.imgur.com/ZoUvU.png. I want to choose the pic form the folder gallery.

Do you know how to modify the code?

I used:

Intent intent = new Intent();
intent.setComponent(new ComponentName("com.android.gallery", "com.android.camera.GalleryPicker"));

//   intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);

Log.i("aa","adafdsfa");
startActivityForResult(intent, 1);

Through I get the folder gallery, but I cannot get the pic path.

 File dir = new File(Environment.getExternalStorageDirectory().toString() + "/sdcard/yourfolder");
        Log.d("File path ", dir.getPath());
        String dirPath=dir.getAbsolutePath();
        if(dir.exists() && dir.isDirectory()) {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            // tells your intent to get the contents
            // opens the URI for your image directory on your sdcard
                            //its upto you what data you want image or video.
            intent.setType("image/*");
        //  intent.setType("video/*");
            intent.setData(Uri.fromFile(dir));
        //  intent.setType("media/*");
        //  intent.
            startActivityForResult(intent, 1);
        }
        else
        {
            showToast("No file exist to show");
        }   


      protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    // TODO Auto-generated method stub
    super.onActivityResult(requestCode, resultCode, data);

     if (requestCode == 1) {
         if (data==null) {
            showToast("No image selected");
            //finish();
        }
         else
         {
         Uri selectedImageUri = data.getData();

      //  String filemanagerstring = selectedImageUri.getPath();

         //MEDIA GALLERY
       String  selectedImagePath = getPath(selectedImageUri);

         if(selectedImagePath!=null)
         {
             Intent intent = new Intent();
             intent.setAction(Intent.ACTION_VIEW);
             intent.setData(selectedImageUri);
             startActivity(intent);
         }

         else
         {
             showToast("Image path not correct");
         }


     }
        }

}
