Android Phonegap 应用程序 - 将 activity 置于最前面
Android Phonegap app - Bringing activity to front
我正在自学如何在 Android 上使用 Phonegap 通知。虽然显示通知似乎是一个相当简单的过程
public void triggerTestNotification(String tag, int id,Context ctxt)
{
Intent notificationIntent = new Intent(context, PallActivity.class);
notificationIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
Intent.FLAG_ACTIVITY_CLEAR_TOP);
notificationIntent.setAction(Intent.ACTION_MAIN);
notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER);
PendingIntent contentIntent = PendingIntent.getActivity(ctxt, 0,
notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
Notification not = new Notification.Builder(ctxt)
.setContentTitle("Title").setContentText("Title")
.setTicker("Tick tock")
.setAutoCancel(true)
.setContentIntent(contentIntent)
.setSmallIcon(ctxt.getApplicationInfo().icon).build();
NotificationManager notificationManager = (NotificationManager)
ctxt.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(tag, id, not);
}
我发现比较困难的是以下内容
- 用户启动应用程序
- 用户离开并开始做其他事情 - 应用程序在后台运行
- 收到通知
- 显示
- 用户点击通知。
此时应用程序应该回到前台。我认为我的意图代码
public class PallActivity extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
finish();
forceMainActivityReload();
}
private void forceMainActivityReload()
{
PackageManager pm = getPackageManager();
Intent launchIntent =
pm.getLaunchIntentForPackage(getApplicationContext().getPackageName());
startActivity(launchIntent);
}
@Override
protected void onResume()
{
super.onResume();
final NotificationManager notificationManager = (NotificationManager)
this.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancelAll();
}
}
会处理这个,但它什么都不做。显然,我在这里弄错了——也许是在 Intent 标志中。如果有人能帮助我走上正轨,我将不胜感激
从您的 oncreate 中删除 finish();
,它会在您继续任何操作之前调用完成。
您打算启动第二个 activity 或至少将 PallActivity 视为第二个 activity,而不是启动 PallActivity, 似乎 .您不需要从 forceMainActivityReload();
中那样启动它。我将从 activity 你希望从通知意图开始,而不是让它变得更复杂和混淆问题。
notification.flags = Notification.FLAG_ONGOING_EVENT | Notification.FLAG_NO_CLEAR;
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
确保您使用的上下文是:
Context context = getApplicationContext();
并且,如评论中所述,从通知中删除这些:
notificationIntent.setAction(Intent.ACTION_MAIN);
notificationIntent.addCategory(Intent.CATEGORY_LAUNCHER);
