当用户点击来自锁定屏幕的通知时启动活动

Question

我希望能够在设备锁定时点击通知，并在未解锁设备的情况下启动活动。

我添加一些标志到活动中的onCreate()方法，其允许将被显示的活动时，该设备被锁定：

Window window = this.getWindow(); 
window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); 
window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED); 
window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); 
window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); 

这是创建通知的代码：

Intent intent = new Intent(this, MainActivity.class); 
PendingIntent pendingIntent = PendingIntent.getActivity(
     this, 
     0, 
     intent, 
     PendingIntent.FLAG_UPDATE_CURRENT); 

Notification notification = new Notification.Builder(this) 
     .setContentIntent(pendingIntent) 
     .setContentTitle("Title") 
     .setSmallIcon(android.R.drawable.ic_menu_more) 
     .build(); 

NotificationManager notificationManager = 
     (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 

notificationManager.notify(1, notification); 

我还添加showOnLockScreen="true"到清单：

<activity 
    android:name=".MainActivity" 
    android:label="@string/app_name" 
    android:showOnLockScreen="true" 
    android:theme="@style/AppTheme.NoActionBar"> 
    <intent-filter> 
     <action android:name="android.intent.action.MAIN" /> 

     <category android:name="android.intent.category.LAUNCHER" /> 
    </intent-filter> 
</activity> 

件事情是工作：

• 当设备被锁定的活性显示（例如，如果我留在前台活动并锁定手机的活动仍然对前景无需解锁手机）
• 如果我点击的通知时，手机被锁定，要求我先解锁，然后活动显示

我希望能够做同样的，但没有解锁设备。
我错过了什么？

试试这个！

private NotificationCompat.Builder mBuilder; 

Intent notifyIntent = new Intent(getApplicationContext(), MainActivity.class); 
    notifyIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK); 
    PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notifyIntent, 0); 
    mBuilder = new NotificationCompat.Builder(this) 
      .setSmallIcon(getNotificationIcon()) 
      .setContent(remoteViews) 
      .setContentIntent(pendingIntent) 
      .setOnlyAlertOnce(true) 
      .setOngoing(true); 

这是方法获取设备5.0通知图标和低于下

private int getNotificationIcon() { 
    boolean useWhiteIcon = (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP); 
    return useWhiteIcon ? R.drawable.notification_icon : R.mipmap.ic_launcher; 
} 

删除代码中的onCreate

Window window = this.getWindow(); 
window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); 
window.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED); 
window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); 
window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
