选择系统图片方法时返回图片真实路径

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {      if (resultCode == RESULT_OK){    //拍照或者选择图片    if (requestCode == RESULT_CAPTURE_IMAGE || requestCode == RESULT_CHOOSE_IMAGE) {    try {        Uri uri = data.getData();      String[] proj = { MediaStore.Images.Media.DATA };      Cursor actualimagecursor = managedQuery(uri,proj,null,null,null);      int actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);      actualimagecursor.moveToFirst();      String img_path = actualimagecursor.getString(actual_image_column_index);      System.out.println("图片真实路径："+img_path);//    //    ContentResolver resolver = getContentResolver();//    Uri uri = data.getData();//    System.out.println("选择图片路径：" + uri);//    Bitmap img = MediaStore.Images.Media.getBitmap(resolver,uri);////    Bitmap bitmap = BitmapFactory.decodeStream(resolver.openInputStream(uri));////    Bitmap img= (Bitmap)data.getExtras().get("data");//获取缩略图//    try { // 压缩图片//    File file = new File(tempPath);//    FileOutputStream outputStream = null;//    outputStream = new FileOutputStream(file);////    if (img.getWidth() > 800 || img.getHeight() > 600) {//    img = Bitmap.createScaledBitmap(img, 800, 600, false);//    }//    img.compress(Bitmap.CompressFormat.JPEG, 90, outputStream);//    outputStream.flush();//    outputStream.close();//    //    sendFile(file,uri.toString());//发送图片////    sendFile(tempPath);//发送图片//    //    } catch (IOException e) {//    e.printStackTrace();//    }////    img = null;//    System.gc();    } catch (OutOfMemoryError e) {    MyMethods.showMsg("获取图出错,请重新操作",this);    e.printStackTrace();    } catch (Exception e) {    e.printStackTrace();    } }    }    }
