Question

我正在玩穿戴SDK而且我注意到一种奇怪的行为：如果你试图通过手机中的BroadcastReceiver来佩戴语音输入，它就不起作用;似乎穿需要一个Activity来将数据返回到手机。

你之前有过这样的经历吗？

这是我用于我的活动的代码：

package com.tizianobasile.weartest;
import android.app.Activity;
import android.app.Notification;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.NotificationManagerCompat;
import android.support.v4.app.NotificationCompat;
import android.support.v4.app.RemoteInput;
import android.view.View;
import android.widget.Button;


public class MyActivity extends Activity {
    private Button notificationBtn;
    public static final String ACTION_DEMAND = "com.tizianobasile.weartest.MyActivity.ACTION_DEMAND";
    public static final String EXTRA_MESSAGE = "message";
    public static final String EXTRA_VOICE_REPLY = "reply";

    NotificationCompat.WearableExtender wearableExtender = new NotificationCompat.WearableExtender().setHintShowBackgroundOnly(true);
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
        notificationBtn = (Button) findViewById(R.id.notificationBtn);
        final Activity a = this;
        notificationBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                createNotification();
            }
        });
    }

    private void createNotification(){
        Intent demandIntent = new Intent(this, DemandReceiver.class)
                .putExtra(EXTRA_MESSAGE, "Reply Selected")
                .setAction(ACTION_DEMAND);
        PendingIntent demandPendingIntent = PendingIntent.getActivity(this, 0, demandIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        String replyLabel = getResources().getString(R.string.app_name);
        String[] replyActions = {"Yes", "No"};
        RemoteInput remoteInput = new RemoteInput.Builder(EXTRA_VOICE_REPLY)
                .setLabel(replyLabel)
                .setChoices(replyActions)
                .build();

        NotificationCompat.Action replyAction =
                new NotificationCompat.Action.Builder(R.drawable.ic_reply, "Reply", demandPendingIntent)
                        .addRemoteInput(remoteInput)
                        .build();

        NotificationCompat.WearableExtender wearableExtender =
                new NotificationCompat.WearableExtender()
                        .addAction(replyAction);

        long[] vibration = {0, 1000};

        Notification notification =
                new NotificationCompat.Builder(this)
                        .setContentTitle("Hello Wear")
                        .setContentText("You received a notification")
                        .setSmallIcon(R.drawable.ic_launcher)
                        .setVibrate(vibration)
                        .extend(wearableExtender)
                        .build();

        NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);

        notificationManager.notify(1, notification);
    }
}

还有BroadcastReceiver：

package com.tizianobasile.weartest;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.RemoteInput;
import android.util.Log;
import android.widget.Toast;

public class DemandReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("WEAR", "Context: " + context.toString());
        Log.d("WEAR", "Intent: " + intent.toString());
        Log.d("WEAR", "Action" + intent.getAction());
        if(intent.getAction().equals(MyActivity.ACTION_DEMAND)){
            String message = intent.getStringExtra(MyActivity.EXTRA_MESSAGE);
            Log.d("WEAR", "Message from intent: " + message);
            Toast.makeText(context, "Message from intent: " + message, Toast.LENGTH_LONG).show();
            Bundle remoteInput = RemoteInput.getResultsFromIntent(intent);
            CharSequence reply = remoteInput.getCharSequence(MyActivity.EXTRA_VOICE_REPLY);
            Log.d("WEAR", "User replies: " + reply);
            Toast.makeText(context, "User replies: " + reply, Toast.LENGTH_LONG).show();
        }
    }
}

在创建demandPendingIntent时，您基本上会告诉我这将是Activity：

    Intent demandIntent = new Intent(this, DemandReceiver.class)
            .putExtra(EXTRA_MESSAGE, "Reply Selected")
            .setAction(ACTION_DEMAND);
    PendingIntent demandPendingIntent = PendingIntent.getActivity(this, 0, demandIntent, PendingIntent.FLAG_UPDATE_CURRENT);

而不是使用：
PendingIntent getActivity(Context context, int requestCode, Intent intent, int flags)
你需要使用：
PendingIntent.getBroadcast(Context context, int requestCode, Intent intent, int flags)

这将让系统知道您希望PendingIntent处理此Broadcastreceiver。

Android Wear不会返回语音数据
