我正在获取最近的通话记录,因为通话已断开(呼出,呼入)已接听或未接听。
我正在使用电话状态侦听器在通话断开时触发广播,但是一次通话却被多次触发,为什么会这样..??
所以请告诉我如何在一次通话中只触发一次接收器。
这是我的代码
public class BroadcastReceiver extends android.content.BroadcastReceiver{
static boolean iscallended= true;
Context mContext;
TelephonyManager telephony;
private static final String TAG = "CustomBroadcastReceiver";
CustomPhoneStateListener customPhoneStateListener;
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
mContext = context;
Bundle extras = intent.getExtras();
if (extras != null) {
String state = extras.getString(TelephonyManager.EXTRA_STATE);
Log.w("DEBUG", state);
telephony = (TelephonyManager)context.getSystemService(context.TELEPHONY_SERVICE);
if(customPhoneStateListener==null)
{
customPhoneStateListener = new CustomPhoneStateListener();
telephony.listen(customPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
}
}
}
private class CustomPhoneStateListener extends PhoneStateListener
{
private static final String TAG = "CustomPhoneStateListener";
Handler handler=new Handler();
@Override
public void onCallStateChanged(int state, String incomingNumber) {
// TODO Auto-generated method stub
System.out.println(iscallended+ " value of iscancelled ");
switch (state)
{
case TelephonyManager.CALL_STATE_RINGING:
if(!incomingNumber.equalsIgnoreCase(""))
{
//YOUR CODE HERE
}
break;
case TelephonyManager.CALL_STATE_IDLE:
if(iscallended)
{
iscallended = false;
System.out.println("IDLE called");
Toast.makeText(mContext, "IDLE", Toast.LENGTH_SHORT).show();
Intent it = new Intent(mContext,MainActivity.class);
it.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(it);
}
break;
default:
break;
}
super.onCallStateChanged(state, incomingNumber);
telephony.listen(customPhoneStateListener, PhoneStateListener.LISTEN_NONE);
}
}
}
这是清单中的接收器
<receiver android:name="com.example.calllogs.BroadcastReceiver">
<intent-filter >
<action android:name="android.intent.action.PHONE_STATE"/>
</intent-filter>
</receiver>
