如何在锁定屏幕上执行通知操作（单击）？

Question

TL;DR

如何在不解锁的情况下发出在锁定屏幕上执行某些操作的通知？单击一个操作、通知上的一个按钮或只是完整的通知后，我想进行 API 调用（无需输入我的解锁代码）

详情

目标

根据 this question 上的回答，我尝试发出一个通知，其中包含一个在锁定屏幕上有效的操作，而无需解锁设备。该操作不需要任何进一步的界面或交互（想想'send an API request'）。

状态

通知和点击适用于解锁的设备。然而，当锁定时我仍然需要先输入解锁码，所以要么发生了新的事情，要么我只是误解了它应该工作的方式。

如果我理解正确，我可以将我的可见性设置为 'public' 以显示内容（这有效），而不是定义一个动作（这似乎不是 public）我可以处理对（现在可见的）布局的点击。我用下面的代码试过了，但显然它不起作用。

我已经尝试将意图发送到我的应用程序和服务，正如 florian 在下面所建议的那样。

代码

这是我开始通知的代码（它存在于 Activity 中，为方便起见已缩短代码）

private void startNotification() {

    NotificationCompat.Builder builder = 
            new NotificationCompat.Builder(this)
            .setVisibility(Notification.VISIBILITY_PUBLIC)
            .setOngoing(true)
            .setSmallIcon(R.drawable.abc_ic_menu_share_mtrl_alpha)
            .setContentTitle("title text")
            .setContentText("content text");

    Intent openIntent = new Intent(MyMainActivity.this, MyMainActivity.class);
    openIntent.setAction("some_string");
    PendingIntent pOpenIntent = PendingIntent.getActivity(this, 0, openIntent, 0);
    builder.setContentIntent(pOpenIntent);

    RemoteViews view = new RemoteViews(getPackageName(), R.layout.notification);
    builder.setContent(view);

    NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    mNotificationManager.notify(id, builder.build());

}

如前所述，我也尝试了 florian 建议的服务，并将其作为调用：

    Intent yepIntent = new Intent(this, MyIntentService.class);
    yepIntent.setAction("test");
    yepIntent.putExtra("foo", true);
    yepIntent.putExtra("bar", "more info");
    PendingIntent yepPendingIntent = PendingIntent.getService(this, notificationId, yepIntent, PendingIntent.FLAG_CANCEL_CURRENT);
    //builder.addAction(R.drawable.abc_ic_menu_share_mtrl_alpha, "My Action", yepPendingIntent);
    builder.setContentIntent(yepPendingIntent);

锁定屏幕上没有显示该操作，所以我将其更改为您在上面看到的 setContentIntent。结果是一样的，我没有采取任何行动:(

尝试使用 IntentService。将您的意图目标替换为您的意图服务：

    Intent yepIntent = new Intent(context, MyIntentService.class);
    yepIntent.putExtra("foo", true);
    yepIntent.putExtra("bar", "more info");
    PendingIntent yepPendingIntent = PendingIntent.getService(context, notificationId, yepIntent, PendingIntent.FLAG_CANCEL_CURRENT);
    notificationBuilder.addAction(R.drawable.icon_of_choice, "My Action", yepPendingIntent);

在清单中注册您的服务：

  <service
        android:name="app.great.mypackage.MyIntentService"
        android:exported="false"/>

您的服务可能如下所示：

public class MyIntentSerice extends IntentService {
    @Override
    protected void onHandleIntent(Intent intent) {
        Log.d("myapp", "I got this awesome intent and will now do stuff in the background!");
        // .... do what you like
    }
}

这个技巧似乎是为了

使用服务
不是将意图添加为动作或内容意图，而是使用 RemoteViews 方法。

合并后为：

NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
        .setVisibility(Notification.VISIBILITY_PUBLIC)
        .setOngoing(true)
        .setSmallIcon(R.drawable.abc_ic_menu_share_mtrl_alpha)
        .setContentTitle("My notification")
        .setContentText("Hello World!");

int notificationId = 1;
Intent yepIntent = new Intent(this, MyIntentService.class);
yepIntent.setAction("test");
yepIntent.putExtra("foo", true);
yepIntent.putExtra("bar", "more info");
PendingIntent yepPendingIntent = PendingIntent.getService(this, notificationId, yepIntent, PendingIntent.FLAG_CANCEL_CURRENT);

// doesn't show up on my lock-screen
//builder.addAction(R.drawable.abc_ic_menu_share_mtrl_alpha, "My Action", yepPendingIntent);

// asks for unlock code for some reason
//builder.setContentIntent(yepPendingIntent);

// Bingo
RemoteViews view = new RemoteViews(getPackageName(), R.layout.notification);
view.setOnClickPendingIntent(R.id.notification_closebtn_ib, yepPendingIntent);
builder.setContent(view);

结合我链接的问题的答案 (Notification action button not clickable in lock screen) 和上面@florian_barth 给出的答案，我成功了

这个技巧似乎是

添加意图不是作为动作或内容意图，而是使用 RemoteViews 方法。

合并后将是：

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            .setVisibility(Notification.VISIBILITY_PUBLIC)
            .setOngoing(true)
            .setSmallIcon(R.drawable.abc_ic_menu_share_mtrl_alpha)
            .setContentTitle("My notification")
            .setContentText("Hello World!");

    int notificationId = 1;
    Intent yepIntent = new Intent(this, MyIntentService.class);
    yepIntent.setAction("test");
    yepIntent.putExtra("foo", true);
    yepIntent.putExtra("bar", "more info");
    PendingIntent yepPendingIntent = PendingIntent.getService(this, notificationId, yepIntent, PendingIntent.FLAG_CANCEL_CURRENT);

    // doesn't show up on my lock-screen
    //builder.addAction(R.drawable.abc_ic_menu_share_mtrl_alpha, "My Action", yepPendingIntent);

    // asks for unlock code for some reason
    //builder.setContentIntent(yepPendingIntent);

    // Bingo
    RemoteViews view = new RemoteViews(getPackageName(), R.layout.notification);
    view.setOnClickPendingIntent(R.id.notification_closebtn_ib, yepPendingIntent);
    builder.setContent(view);

Answer 3

它也适用于广播接收器和 setAction

PendingIntent pendingIntent = PendingIntent.getBroadcast(..
builder.addAction(..
   .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)

在锁定屏幕上向下滑动通知以展开它，然后点击操作区域以调用广播接收器而无需解锁 phone。
