我尝试创建自定义通知但获得以下异常:

FATAL EXCEPTION: main
android.app.RemoteServiceException: Bad notification posted from package com.my.app: Couldn't expand RemoteViews for: StatusBarNotification(pkg=com.my.app user=UserHandle{0} id=1 tag=null score=0: Notification(pri=0 contentView=com.my.app/0x7f03001b vibrate=null sound=null defaults=0x0 flags=0x2 kind=[null]))

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553)
    at dalvik.system.NativeStart.main(Native Method)

我的代码如下所示:

Intent intent = new Intent(this, MyFragmentActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent launchIntent = PendingIntent.getActivity(this, 0, intent, 0);

RemoteViews notificationView = new RemoteViews(this.getPackageName(), R.layout.notification_layout);
notificationView.setImageViewBitmap(R.id.notification_icon, icon);
notificationView.setTextViewText(R.id.present_text, "Text Test");

Notification.Builder builder = new Notification.Builder(getApplicationContext());
builder
    .setContentTitle("Titel Test")
    .setSmallIcon(R.drawable.ic_launcher_icon)
    .setContentIntent(launchIntent)
    .setOngoing(true)
    .setWhen(0)
    .setTicker("ticker Test")
    .setContent(notificationView);

NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID, builder.getNotification());

布局如下:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/notification_icon"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true" />

    <EditText
        android:id="@+id/present_text"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@id/notification_icon"
        android:gravity="center_vertical" />

</RelativeLayout>

我正在运行android 4.3。我之前尝试过NotificationCompat并得到同样的错误。

有人有想法吗?

您无法将EditText放入RemoteViewsRemoteViews仅限于少数可能的小部件,特别是those documented for use on an app widget。而且,对于Notification,我怀疑AdapterView选项(如ListView)是否有效。

答案 1 :(得分:3)

对我来说,这是因为我在remoteViews TextViews中设置了错误的文本。我这样做了:

remoteViews.setString(R.id.txt, "setText", "text");

使用其中一种方法为我解决了这个问题:

remoteViews.setCharSequence(R.id.txt, "setText", "text");
//Or simply:
remoteViews.setTextViewText(R.id.txt, "text");

答案 2 :(得分:3)

并非所有视图都可以在RemoteView中使用。 RemoteViews对象可以支持以下布局类:

的FrameLayout

的LinearLayout

RelativeLayout的

GridLayout的

AnalogClock

按钮

记时计

的ImageButton

ImageView的

进度

的TextView

ViewFlipper

的ListView

GridView的

StackView

AdapterViewFlipper

您不能使用其他布局类,如Edittext或CustomViews。

如果您的RemoteView中有一个ScrollView,请将其删除。这对我有用。
