Question

我创建了一个示例Android应用程序，用于接收来自 Parse 的推送消息。我跟着this video tutorial。该应用程序运行正常，我能够接收推送通知。

所需的课程如下：

ParseApplication 类：

public class ParseApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        // Add your initialization code here
        Parse.initialize(this, "ygdC4y3uzCe0TOEPOfB1U469Gg5ZJGxF2OGlNKCG", "Tk5ZlDiWWVJm2Xio5IiXk0KI5JM1jrvGPOSpFxzE");

        PushService.setDefaultPushCallback(ParseApplication.this, SampleClass.class);



        ParseUser.enableAutomaticUser();
        ParseACL defaultACL = new ParseACL();

        // If you would like all objects to be private by default, remove this line.
        defaultACL.setPublicReadAccess(true);

        ParseACL.setDefaultACL(defaultACL, true);
    }

}

ParseStarterProjectActivity 类：

public class ParseStarterProjectActivity extends Activity {
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        ParseAnalytics.trackAppOpened(getIntent());


    }
}

SampleClass 类：

public class SampleClass extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sample_class);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.sample_class, menu);
        return true;
    }

}

清单文件：

                <!-- IMPORTANT: Change "com.parse.starter" to match your app's package name. -->
                <category android:name="com.parse.starter" />
            </intent-filter>
        </receiver>

        <activity
            android:name="com.parse.starter.SampleClass"
            android:label="@string/title_activity_sample_class" >
        </activity>
    </application>

</manifest>

现在，我希望在用户收到推送通知时从其中获取文本。如何从通知中获取文本？

这是推送通知服务器的url。

我甚至去了this。

我必须像这样更改 SampleClass Activity ：

public class SampleClass extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sample_class);

        Intent intent = getIntent(); 
        Bundle extras = intent.getExtras(); 
        String jsonData = extras.getString( "com.parse.Data" );

        Log.i("Data Received:", jsonData);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.sample_class, menu);
        return true;
    }

其余的就是这样。我提到this link。
