OssDemo使用临时token权限上传

位置：
 res/layout/content_main.xml
 内容：
 <Button
     style="?android:attr/buttonStyleSmall"
     android:layout_height="wrap_content"
     android:layout_width="wrap_content"
     android:text="@string/upload"
     android:id="@+id/upload" />

函数实现片段：

Button upload = (Button) findViewById(R.id.upload);
 upload.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
         Intent i = new Intent(
                 Intent.ACTION_PICK,
                 android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
         startActivityForResult(i, RESULT_UPLOAD_IMAGE);
     }
 }

函数实现片段：

@Override
 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     super.onActivityResult(requestCode, resultCode, data);
     if ((requestCode == RESULT_UPLOAD_IMAGE || requestCode == RESULT_PAUSEABLEUPLOAD_IMAGE) && resultCode == RESULT_OK && null != data) {
         Uri selectedImage = data.getData();
         String[] filePathColumn = { MediaStore.Images.Media.DATA };
         Cursor cursor = getContentResolver().query(selectedImage,
                 filePathColumn, null, null, null);
         cursor.moveToFirst();
         int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
         String picturePath = cursor.getString(columnIndex);
         Log.d("PickPicture", picturePath);
         cursor.close();
         try {
             Bitmap bm = ImageDisplayer.autoResizeFromLocalFile(picturePath);
             displayImage(bm);
             File file = new File(picturePath);
             displayInfo("文件: " + picturePath + "\n大小: " + String.valueOf(file.length()));
         }
         catch (IOException e) {
             e.printStackTrace();
             displayInfo(e.toString());
         }
         //根据操作不同完成普通上传或者断点上传
         if (requestCode == RESULT_UPLOAD_IMAGE) {
             final EditText editText = (EditText) findViewById(R.id.edit_text);
             String objectName = editText.getText().toString();
             //调用简单上传接口上传
             ossService.asyncPutImage(objectName, picturePath, getPutCallback(), new ProgressCallbackFactory<PutObjectRequest>().get());
         }
     }
 }

这里省略了对上传结果的处理，可以参考源码中的onSuccess和onFailure的处理。
