[英]Launch Activity when notification is clicked
當我從狀態欄中單擊通知時,我想打開一個活動。 我已經在StackOverflow上看到了這個答案,但是這些答案都不適合我。 這是我的代碼:
notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setProgress(100, 0, false);
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSmallIcon(R.drawable.ic_action_file_cloud_upload);
notificationBuilder.setContentTitle(getString(R.string.notification_upload_title));
//when this notification is clicked and the upload is running, open the upload fragment
Intent notificationIntent = new Intent(this, MainActivity.class);
notificationIntent.setAction(Intent.ACTION_MAIN);
notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK);
// set intent so it does not start a new activity
PendingIntent intent = PendingIntent.getActivity(this, 1, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_ONE_SHOT);
notificationBuilder.setContentIntent(intent);
this.startForeground(NOTIFICATION_ID_UPLOADING_PROGRESS, notificationBuilder.build());
的Manifest.xml
<activity
android:name="com.android.app.MainActivity_"
android:label="@string/app_short_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
終於我意識到我必須寫這個:
Intent notificationIntent = new Intent(this, MainActivity_.class);
代替
Intent notificationIntent = new Intent(this, MainActivity.class);
非常感謝您的所有回答!
我認為您不需要所有這些標志和配置就可以從PendingIntent中打開活動。 你當然不需要
notificationIntent.setAction(Intent.ACTION_MAIN);
notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER);
PendingIntent.FLAG_ONE_SHOT
刪除它們,然后重試。
此外:MainActivity的包名稱是否符合預期( com.android.app.MainActivity )?
請嘗試以下解決方案,希望它對您有用
Intent intent = new Intent(this,YourActivity....class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent blogIntent = PendingIntent.getActivity(this, INT CONSTANTS, intent,
PendingIntent.FLAG_ONE_SHOT);
從通知
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
.
.
.
notificationBuilder.setContentIntent(blogIntent);
Notification notification = notificationBuilder.build();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(Constants.NOTIFICATION_NEW_BLOG, notification);
您必須在清單中添加自定義接收方
<receiver
android:name=".IntentReceiver"
android:exported="false">
<intent-filter>
<!-- add notification action here -->
</intent-filter>
</receiver>
在Intent接收器類中,在recipe方法上重寫
public class IntentReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
//call your activity here
}
}
Use this code
/* Invoking the default notification service */
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setContentTitle("Test");
mBuilder.setContentText(text2);
mBuilder.setSmallIcon(R.drawable.icon);
/* Creates an explicit intent for an Activity in your app */
Intent resultIntent = new Intent(this, NotificationListActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(NotificationListActivity.class);
/* Adds the Intent that starts the Activity to the top of the stack */
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent =stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
/* notificationID allows you to update the notification later on. */
mNotificationManager.notify(9999, mBuilder.build());
