在展开通知后更新Android中的通知文本

Question

我试图创建一个在展开后完全更改其文本的通知。

例如，正常的非扩展通知会说＆＃34;点击做X＆＃34;这将有一个未决的意图。

如果用户展开通知，则文本将更改为＆＃34;以下是您可以执行的一些操作＆＃34;将一些操作添加到通知中。

Answer 1

设置通知构建器，如下所示：

NotificationCompat.Builder builder=new NotificationCompat.Builder(mContext);

builder.setContentTitle("Title!");
builder.setContentText("Tap to do x");
builder.setTicker("Ticker");
builder.setSmallIcon(drawable);
builder.setAutoCancel(true);
builder.addAction(icon, "Open App", resultPendingIntent)
builder.setContentIntent(resultPendingIntent)
builder.setPriority(Notification.PRIORITY_MAX);     

//Content hen expanded
NotificationCompat.BigTextStyle bigText=new NotificationCompat.BigTextStyle();
bigText.bigText("Here are some actions you can do");
bigText.setSummaryText("Summary line");
bigText.setBigContentTitle("expanded title");


builder.setStyle(bigText);

Intent intent=new Intent(mContext, YourActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(mContext);
stackBuilder.addParentStack(ParentActivity.class);

stackBuilder.addNextIntent(intent);
PendingIntent pendingIntent=stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

builder.setContentIntent(pendingIntent);

NotificationManager manager=(NotificationManager)
        mContext.getSystemService(Context.NOTIFICATION_SERVICE);

manager.notify(0, builder.build());
