我认为您需要将此行放在 object.put(...);
之后
object.saveInBackground();
参考http://docs.parseplatform.org/android/guide/，看到"Saving Objects"和"The Local Datastore."他们将信息放入对象后有如下代码
pinInBackground();
saveInBackground();
还有一个建议，出于安全原因，您的applicationID、clientKey和您的服务器地址应该被屏蔽。
首先你不应该公开任何这个 - applicationId, clientKey, server{or any other key} 你应该像这样将它添加到你的 gradle.property
MyApiKey="2000000000000000"
得到它，这样在你的
gradle buildTypes.each {it.buildConfigField 'String', 'TOKEN_API_KEY', MyApiKey}
您可以通过这种方式使用任何 activity 中的密钥
字符串我的 = BuildConfig.TOKEN_API_KEY
因此，例如，在您的代码中，您将拥有 .clientKey(BuildConfig.TOKEN_API_KEY)
针对你的问题
您应该记录您的响应，这不仅可以让您更轻松地调试或查看结果值，您还可以设置断点并进入、退出并查看发生了什么。要设置日志，您需要 Log.d(TAG, value) 其中 TAG 是 private static final String TAG = yourClass.class.getSimpleName();
您需要将解析信息放入另一个扩展应用程序的class。
查看我对其他人的回答 post。
一旦你这样做了，MainActivity 就可以根据你的需要托管你的应用程序。如果您有任何问题，请告诉我
这是关于如何在任何 ANDROID 工作室项目上设置 PARSE 的解决方案！
第 1 步：我在 build.gradle(Module:) 中的依赖项下编写了以下代码：-
compile 'com.parse:parse-android:1.15.7'
（下一次同步您的 GRADLE）
通过这样做，您将能够神奇地使用解析关键字和方法。
第 2 步：现在是转折点。您不需要在您的 ANDROID 项目中安装 STARTERAPPLICATION JAVA CLASS。
也不需要其他 CLASS 人！
还添加以下内容
/要放入 ANDROIDMANIFEST 中的代码：/
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
现在进入第 3 步
第 3 步：******这是重要部分****
你必须初始化你的 PARSE，（由于我的知识有限，我在 MAINACTIVITY 的 ONCREATE 函数中初始化了它）
Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
.applicationId("YOUR_APP_ID")
.clientKey("YOUR_MASTER_KEY")
.server("YOUR_SERVER_URL")
.build()
);
大功告成！！！您已成功设置 PARSE!!!!!!!
