问题描述
我无法弄清楚下面的代码出了什么问题。我还检查了两次注册接收器。但事实并非如此。还是我想念一些东西。
请帮忙。我真的很需要:(
I Could not figure out what is wrong with below code. I also checked about registering receiver twice. But that's also not the case. or may be I am missing something. Could any please help. I really need it. :(
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.os.IBinder;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;
/**

public class CallNotifierService extends Service
{
private static final String ACTION_IN = "android.intent.action.PHONE_STATE";
private static final String ACTION_OUT = "android.intent.action.NEW_OUTGOING_CALL";
private CallBr br_call;
@Override
public IBinder onBind(Intent arg0)
{
return null;
}
@Override
public void onDestroy()
{
Log.d("service", "destroy");
this.unregisterReceiver(this.br_call);
super.onDestroy();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
final IntentFilter filter = new IntentFilter();
filter.addAction(ACTION_OUT);
filter.addAction(ACTION_IN);
this.br_call = new CallBr();
this.registerReceiver(this.br_call, filter);
return START_NOT_STICKY;
}
public class CallBr extends BroadcastReceiver
{
Bundle bundle;
String state;
String inCall, outCall;
public boolean wasRinging = false;
public boolean answered = false;
public boolean outgoing = false;
@Override
public void onReceive(Context context, Intent intent)
{
if (intent.getAction().equals(ACTION_IN))
{
if ((bundle = intent.getExtras()) != null)
{
state = bundle.getString(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
{
inCall = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
wasRinging = true;
Toast.makeText(context, "Incoming Call : " + inCall, Toast.LENGTH_LONG).show();
}
else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK))
{
if (wasRinging == true)
{
answered = true;
Toast.makeText(context, "Answered", Toast.LENGTH_LONG).show();
}
}
else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE))
{
wasRinging = false;
Toast.makeText(context, "Disconnected", Toast.LENGTH_LONG).show();
}
}
}
else if (intent.getAction().equals(ACTION_OUT))
{
if ((bundle = intent.getExtras()) != null)
{
outCall = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Toast.makeText(context, "Outgoing Call : " + outCall, Toast.LENGTH_LONG).show();
outgoing = true;
}
}
}
}
}
下面是我从中调用的活动
Below is the activity I am calling it from
public class MyActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.roaming);
Intent intent = new Intent(this, CallNotifierService.class);
startService(intent);
}
.
.
.
}

推荐答案
实际上..代码没有错。触发它的系统。有时是2倍,而其他时候是4倍。
Actually .. there is nothing wrong with the code. its System who triggers this. some time its 2 times.. other times it touches 4 times.
所以我们最好的办法是在代码本身中处理它。
So the best we can do it handle it in the code itself.
