    }

    @Override

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_mobile, menu);
        return true;
    }

    @Override

        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

NotificationActivity.java

        Button edit = (Button) findViewById(R.id.button2);
        edit.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(NotificationActivity.this, MobileActivity.class);
                startActivity(intent);
                finish();

            }
        });
    }
}

这是我的移动活动和通知活动代码。通知会在穿戴设备模拟器上弹出，但尝试从穿戴设备打开到手机时，应用程序崩溃。

最佳答案

这是一个工作代码。

NotificationManager mNotificationManager = (NotificationManager)
        this.getSystemService(Context.NOTIFICATION_SERVICE);

Intent resultIntent = new Intent(this, SCNotifListActivity.class);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//action for google wear
NotificationCompat.Action action = new NotificationCompat.Action(R.drawable.sc_app_icon,getString(R.string.app_name), resultPendingIntent);
NotificationCompat.Builder mBuilder =
        new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.notification_icon)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                .setContentTitle(getApplicationContext().getString(R.string.app_name))
                .setContentText(message).setNumber(count).setAutoCancel(true)
                .extend(new NotificationCompat.WearableExtender().addAction(action));
mBuilder.setContentIntent(resultPendingIntent);
mNotificationManager.notify(0, mBuilder.build());
