Question

我如何检测何时连接拨出电话。我的代码在下面，但是当有来电时，它会进入 if（intent.getStringExtra（TelephonyManager.EXTRA_STATE）.equals（TelephonyManager.EXTRA_STATE_RINGING））

当没有活动时，它会进入

else if（intent.getStringExtra（TelephonyManager.EXTRA_STATE）.equals（TelephonyManager.EXTRA_STATE_IDLE））

当incomingcall回答时，它会进入此状态并且传出呼叫将进入此状态。

else if（intent.getStringExtra（TelephonyManager.EXTRA_STATE）.equals（TelephonyManager.EXTRA_STATE_OFFHOOK））

现在当传出呼叫它的状态是摘机时我怎么知道我的传呼呼叫何时连接。

谢谢

@Override
public void onReceive(Context context, Intent intent) {
    // TODO: This method is called when the BroadcastReceiver is receiving
    // an Intent broadcast.
    if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING)){
        String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
        Toast.makeText(context, "Call From : " + incomingNumber, Toast.LENGTH_LONG).show();

    }
    else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_IDLE)){
        Toast.makeText(context,TelephonyManager.EXTRA_STATE_IDLE,Toast.LENGTH_LONG).show();
    }
    else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){
        Toast.makeText(context,TelephonyManager.EXTRA_STATE_OFFHOOK,Toast.LENGTH_LONG).show();
    }
}

在Android Manifest文件中添加此项。声明广播接收器。

    <receiver
        android:name=".OutCallLogger"
        android:enabled="true"
        android:exported="true" >
            <intent-filter>
                <action android:name="android.intent.action.PRECISE_CALL_STATE" />
                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            </intent-filter>
    </receiver>

在android清单文件中添加以下权限。

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.READ_PRECISE_PHONE_STATE" />

还在清单文件中添加此行。

<uses-feature android:name="android.hardware.telephony">
</uses-feature>

这是你的课程，用于获取拨出电话的预先调用状态。

public class OutCallLogger extends BroadcastReceiver {
public OutCallLogger() {

@Override

    this.context1= context;
    try {
        //String serviceManagerName = "android.os.IServiceManager";
        String serviceManagerName = "android.os.ServiceManager";
        String serviceManagerNativeName = "android.os.ServiceManagerNative";
        String telephonyName = "com.android.internal.telephony.ITelephony";


        telephonyClass = Class.forName(telephonyName);
        telephonyStubClass = telephonyClass.getClasses()[0];
        serviceManagerClass = Class.forName(serviceManagerName);
        serviceManagerNativeClass = Class.forName(serviceManagerNativeName);

        Method getService = // getDefaults[29];
                serviceManagerClass.getMethod("getService", String.class);

        Method tempInterfaceMethod = serviceManagerNativeClass.getMethod(
                "asInterface", IBinder.class);

        Binder tmpBinder = new Binder();
        tmpBinder.attachInterface(null, "fake");

        serviceManagerObject = tempInterfaceMethod.invoke(null, tmpBinder);
        IBinder retbinder = (IBinder) getService.invoke(serviceManagerObject, "phone");
        Method serviceMethod = telephonyStubClass.getMethod("asInterface", IBinder.class);
        Method[] aClassMethods = telephonyClass.getDeclaredMethods();
        for(Method m : aClassMethods)
        {
            //Log.e("MEthods", m.getName());
        }
        telephonyObject = serviceMethod.invoke(null, retbinder);
        //telephonyCall = telephonyClass.getMethod("call", String.class);
        telephonyEndCall = telephonyClass.getMethod("getPreciseCallState");
        //telephonyAnswerCall = telephonyClass.getMethod("answerRingingCall");
        Log.e("CallState",telephonyEndCall.invoke(telephonyObject).toString());
        Toast.makeText(context1, " "+telephonyEndCall.invoke(telephonyObject).toString(), Toast.LENGTH_LONG).show();

        telephonyEndCall.invoke(telephonyObject);

    } catch (Exception e) {
        e.printStackTrace();

    }

}

}
