废话少说，直接上代码：

package com.dannalapp.main;

import com.avos.avoscloud.GetCallback;
import com.avos.avoscloud.GetDataCallback;
import com.avos.avoscloud.ParseException;
import com.avos.avoscloud.ParseFile;
import com.avos.avoscloud.ParseObject;
import com.avos.avoscloud.ParseQuery;
import com.avos.avoscloud.SaveCallback;

import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;

public class TestActivity extends Activity {
    
    ParseFile file;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);


        try {
            file = ParseFile.parseFileWithAbsoluteLocalPath("test.jpg",
                    Environment.getExternalStorageDirectory() + "/test.jpg");
            file.saveInBackground(new SaveCallback() {
                
                @Override
                public void done(ParseException arg0) {
                    saveObject();
                    
                }
            });
            
        } catch (Exception e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        
        

        ParseQuery<ParseObject> query = ParseQuery.getQuery("MyObject");

        query.getInBackground("525bd3ade4b0d1da567d970c",
                new GetCallback<ParseObject>() {
                    public void done(ParseObject object, ParseException e) {
                        if (e == null) {
                            getParseObject(object);
                            System.err.println("qs");

                        } else {
                            System.err.println("qf");
                        }
                    }
                });

        

    }

    ParseObject mParseObject;
    ParseFile mParseFile;

    public void getParseObject(ParseObject parseObject) {
        mParseObject = parseObject;

        mParseFile = mParseObject.getParseFile("file");
        mParseFile.getDataInBackground(new GetDataCallback() {

            @Override
            public void done(byte[] arg0, ParseException arg1) {
                // TODO Auto-generated method stub

            }
        });

        String str = mParseFile.getName();

        System.err.println("getParseObject - " + str);

    }
    
    ParseObject object = new ParseObject("MyObject");
    public void saveObject() {
        object.put("file", file);
        object.saveInBackground();
    }
    
    

}
