要求是制作自定义通知,因为Android的默认通知仅允许图像。因此,我详细介绍了如何在扩展时附加自定义UI以进行通知,准备好的答案是创建自定义视图并传递给通知管理器并允许从API级别16开始。所以我做了一个,这里是我的布局xml代码 - filename:notification_custom_view_new:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/GhostWhite">
<RelativeLayout
android:id="@+id/header"
android:layout_width="match_parent"
android:layout_height="65dp">
<ImageView
android:id="@+id/big_icon"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_centerVertical="true"
android:layout_marginLeft="12dp"
android:scaleType="fitCenter" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignBottom="@+id/big_icon"
android:layout_alignTop="@+id/big_icon"
android:layout_toRightOf="@+id/big_icon"
android:gravity="center_vertical"
android:orientation="horizontal"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:weightSum="2">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1.6"
android:orientation="vertical">
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:maxLines="1"
android:text="Title"
android:textColor="@color/colorBlackDimText"
android:textSize="16sp"
android:textStyle="bold" />
<TextView
android:id="@+id/message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:maxLines="2"
android:paddingTop="2dp"
android:text="message"
android:textColor="@color/colorBlackDimText"
android:textSize="14sp" />
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.4"
android:gravity="center">
<TextView
android:id="@+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:maxLines="2"
android:padding="8dp"
android:text="24:59"
android:textColor="@color/colorBlackDimText"
android:textSize="12sp" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
<View
android:id="@+id/shadow"
android:layout_width="match_parent"
android:layout_height="5dp"
android:layout_below="@+id/header"
android:background="@drawable/shadow" />
<ImageView
android:id="@+id/big_picture"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/header"
android:src="@drawable/vector_icon_collections"
android:minHeight="240dp"
android:scaleType="fitCenter" />
</RelativeLayout>
我在代码中引用它的方式:
private RemoteViews assignRemote(Bitmap bitmap, String title, String message){
RemoteViews expandedView = new RemoteViews(Application.getInstance().getPackageName(),
R.layout.notification_custom_view_new);
expandedView.setTextViewText(R.id.title, title);
expandedView.setTextViewText(R.id.message, message);
expandedView.setImageViewBitmap(R.id.big_picture, bitmap);
expandedView.setImageViewResource(R.id.big_icon, R.mipmap.ic_launcher);
expandedView.setTextViewText(R.id.time, getOnlyHrsMin());
return expandedView;
}
将自定义视图分配给通知管理器:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
notification.bigContentView = assignRemote(bitmap, title, message);
}
但是这给了我一个错误的通知错误,我已经在stackoverflow上找到了超过15个相同的问题而没有正确的答案..有些人认为它是一个资源缺失,因此错误。我确信从我的角度来看,没有任何值为null,也没有资源丢失错误在我的远程视图中没有传递。
任何帮助都将受到赞赏,而且我已经尝试了大约几天来跟踪错误,但似乎没有什么好事发生。请帮帮我!
通知Obj Init:
NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
bigPictureStyle.setBigContentTitle(title);
bigPictureStyle.setSummaryText(Html.fromHtml(message).toString());
bigPictureStyle.bigPicture(bitmap);
Notification notification;
notification = mBuilder.setSmallIcon(icon).setTicker(title).setWhen(0)
.setAutoCancel(true)
.setContentTitle(title)
.setContentIntent(resultPendingIntent)
.setSound(alarmSound)
.setLights(Color.WHITE, 1500, 2000)
//.setStyle(bigPictureStyle)
.setWhen(getTimeMilliSec(timeStamp))
.setSmallIcon(iconToUse())
.setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
.setContentText(message)
.build();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
notification.bigContentView = assignRemote(bitmap, title, message);
}
NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(Config.NOTIFICATION_ID_BIG_IMAGE, notification);

附加布局UI的屏幕截图:
答案 0 :(得分:2)
删除您在布局中用作阴影的“视图”(或使用TextView替换视图),它可以正常工作。用于Remoteview的XML应该使用具有@android.widget.RemoteViews.RemoteView
注释的Views。由于普通View没有此注释,因此不能在xml中使用它。

您无法将EditText放入RemoteViews。 RemoteViews仅限于少数可能的小部件,对于Notification,我怀疑AdapterView选项(如ListView)是否可以正常工作。have a look here。希望这会根据我的经验帮助你。
