如何变化的行动在Android Wear的动态图标 [英] How change action icons dynamically in android wear

问题描述

我创建了一个Android Wear的应用程序，它支持我的掌上电脑的应用程序。
显示通知和相关行动Android Wear应用之上执行。

I have created a android wear app which support my handheld application. The android wear app showing notifications and related actions top perform.

我创建的Andr​​oid Wear通知，并增加了两个行动的暂停，恢复和终止

I have created android wear notifications and added two actions for pause,resume and stop

我需要更换，通过动态的简历行动暂停的动作，这意味着如果用户preSS暂停行动需要更改恢复行动。

I need to replace the pause action by resume action dynamically, that means if user press pause action need to change to resume action.

我的code是

Intent pauseIntent = new Intent(getApplicationContext(), PauseActivity.class);
         PendingIntent pausePendingIntent = PendingIntent.getActivity(getApplicationContext(),
                 0, pauseIntent, PendingIntent.FLAG_UPDATE_CURRENT);

         Intent stopIntent = new Intent(getApplicationContext(), StopActivity.class);
         PendingIntent stopPendingIntent = PendingIntent.getActivity(getApplicationContext(),
                 0, stopIntent,  PendingIntent.FLAG_UPDATE_CURRENT);


         Notification notification =
                    new NotificationCompat.Builder(getApplicationContext())
                            .setSmallIcon(R.drawable.icon)
                            .setContentTitle("Swipe up to view")
                            .setDeleteIntent(deletePendingIntent)
                            .extend(new WearableExtender()
                                    .setDisplayIntent(displayPendingIntent))
                            .addAction(R.drawable.pause_btn, "Pause", pausePendingIntent)
                            .addAction(R.drawable.stop_btn, "Stop", stopPendingIntent)
                                    .build();

我的要求是当用户点击暂停按钮，我需要通过Resume图标改变这种状况。

My requirement is When user clicks on the pause button i need to change that by Resume Icon.

提前感谢所有...

推荐答案

您需要在用户点击的行动，以刷新​​它只是张贴新的通知。结果
最老的通知将被更新，所以当发布一个新的改变暂停图标恢复图标+做同样的标签。

Solution

You need to just post new notification when user clicks that action in order to refresh it.
The old notification will be updated so while posting a new one change the "pause" icon to "resume" icon + do the same with labels.

定义你的意图那样：

Intent pauseIntent = new Intent(MediaPlayerActionsReceiver.ACTION_PAUSE, null, context, MediaPlayerActionsReceiver.class);
PendingIntent pausePendingIntent = PendingIntent.getBroadcast(context, 0, pauseIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Intent resumeIntent = new Intent(MediaPlayerActionsReceiver.ACTION_RESUME, null, context, MediaPlayerActionsReceiver.class);
PendingIntent resumePendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, resumeIntent, PendingIntent.FLAG_UPDATE_CURRENT);

Intent stopIntent = new Intent(MediaPlayerActionsReceiver.ACTION_STOP, null, context, MediaPlayerActionsReceiver.class);
PendingIntent stopPendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, stopIntent, PendingIntent.FLAG_UPDATE_CURRENT);

他们都将交付给同一组件（ MediaPlayerActionsReceiver ），但与不同的操作声明。

They all will be delivered to the same component (MediaPlayerActionsReceiver), but with different action declared.

然后创建MediaPlayerActionsReceiver类：

Then create your MediaPlayerActionsReceiver class:

public class MediaPlayerActionsReceiver extends BroadcastReceiver {

    public final static String ACTION_PAUSE = "com.example.package.receiver.action_pause";
    public final static String ACTION_RESUME = "com.example.package.receiver.action_resume";
    public final static String ACTION_STOP = "com.example.package.receiver.action_stop";
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent==null)
            return;

        final String action = intent.getAction(); 
        if(ACTION_PAUSE.equals(action)) {
            // handle pause action and refresh notification
        } else if(ACTION_RESUME.equals(action)) {
            // handle resume action and refresh notification
        } else if(ACTION_STOP.equals(action)) {
            // handle stop action and refresh notification
        }
    }
}

最后一步就是声明你的接收机 AndroidManifest ：

<receiver android:name="com.example.package.receiver.MediaPlayerActionsReceiver" android:enabled="true" android:exported="false">
    <intent-filter>
        <action android:name="com.example.package.receiver.action_pause" />
        <action android:name="com.example.package.receiver.action_resume" />
        <action android:name="com.example.package.receiver.action_stop" />
    </intent-filter>
</receiver>
