当用户点击通知时如何开始活动? [英] How to start activity when user clicks a notification?

问题描述

我正在尝试转换我在教程中找到的一些代码供我自己使用.最初，当用户单击我的应用程序生成的通知时，代码会启动系统联系人列表.我正在尝试启动我自己的 Activity 而不是启动联系人列表，但它不起作用.更具体地说，什么也没有发生.没有错误，我的 Activity 也没有加载.点击后通知窗口消失，原来的Activity依然可见.

I am attempting to convert some code I found in a tutorial for my own use. Originally, the code launched the system contacts list when the user would click a notification generated by my app. I am trying to start an Activity of my own instead of launching the contact list, but it's not working. More specifically, nothing happens. There is no error, and my Activity doesn't load either. The notification window disappears after clicking, and the original Activity is still visible.

这是我的代码:

public class MyBroadcastReceiver extends BroadcastReceiver {
    private NotificationManager mNotificationManager;
    private int SIMPLE_NOTFICATION_ID;

    public void onReceive(Context context, Intent intent){
        Bundle extras = intent.getExtras();

        String deal = (String) extras.get("Deal");
        String title = "Deal found at " + (String) extras.get("LocationName");

        mNotificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notifyDetails = new Notification(R.drawable.icon, title,System.currentTimeMillis());

        Class ourClass;
        try {
            ourClass = Class.forName("com.kjdv.gpsVegas.ViewTarget");
            Intent startMyActivity = new Intent(context, ourClass);

            PendingIntent myIntent = PendingIntent.getActivity(context, 0,startMyActivity, 0);
            notifyDetails.setLatestEventInfo(context, title, deal, myIntent);
            notifyDetails.flags |= Notification.FLAG_AUTO_CANCEL;
            notifyDetails.flags |= Notification.DEFAULT_SOUND;
            mNotificationManager.notify(SIMPLE_NOTFICATION_ID, notifyDetails);
        }
        catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
}

这是我在 AndroidManifext.xml 文件中的条目...

This is my entry in the AndroidManifext.xml file...

  <activity android:name=".ViewTarget" android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.kjdv.gpsVegas.ViewTarget" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
   </activity>

这是我要启动的Activity...

public class ViewTarget extends ListActivity {
    public ListAdapter getListAdapter() {
        return super.getListAdapter();
    }

    public ListView getListView() {
        return super.getListView();
    }

    public void setListAdapter(ListAdapter adapter) {
        super.setListAdapter(adapter);
    }

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.locations);
        Log.v("db", "Inside ViewTarget");
    }
}

推荐答案

我找到了问题所在.我忘记在清单文件的活动声明中包含包名称.

I figured out the problem. I forgot to include the package name in the activity declaration in the Manifest file.

错误:

activity android:name=".ViewTarget" android:label="@string/app_name" 

正确:

activity android:name="com.kjdv.gpsVegas.ViewTarget" android:label="@string/app_name"
