考虑家庭,办公室和游乐场等三个地点。每当我进入和退出该位置时,它都会显示消息提示。 这是我添加多个接近点的主要活动 的 MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

}
locationManager.addProximityAlert(latitude,
longitude,
POINT_RADIUS,
PROX_ALERT_EXPIRATION,
proximityIntent
);
IntentFilter filter = new IntentFilter(PROX_ALERT_INTENT);
registerReceiver(new ProximityIntentReceiver(), filter);
}
//这是我未决的意向接收器,我通知输入和现有警报 的 PendingIntentReceiver.java
public class ProximityIntentReceiver extends BroadcastReceiver {
private static final int NOTIFICATION_ID = 1000;
double lat,lng;
String d="";
@Override
public void onReceive(Context context, Intent intent) {
String key = LocationManager.KEY_PROXIMITY_ENTERING;
Boolean entering = intent.getBooleanExtra(key, false);
lat=intent.getDoubleExtra("lat",0.00);

if (entering) {
Log.d(getClass().getSimpleName(), "entering");

}
NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent notificationIntent = new Intent(context, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, (int) System.currentTimeMillis(), notificationIntent, 0);
Notification n = new Notification.Builder(context)
.setContentTitle("Proximity")
.setContentText("Subject: "+d)
.setSmallIcon(R.drawable.hell)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.build();
notificationManager.notify((int) System.currentTimeMillis(), n);
}
}
答案 0 :(得分:0)
试试这个:
Intent notificationIntent = new Intent(context, MainActivity.class);
notificationIntent.setAction(Long.toString(System.currentTimeMillis()));
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(intent);
PendingIntent pendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
Notification n = new Notification.Builder(context)
.setContentTitle("Proximity")
.setContentText("Subject: "+d)
.setSmallIcon(R.drawable.hell)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
.build();
notificationManager.notify((int) System.currentTimeMillis(), n);
