当电话铃响时,我设法准备了一项活动.现在我需要知道如何取消这个活动,当我打电话或拒绝电话时.我是否打电话给EXTRA_STATE_IDLE？EXTRA_STATE_OFFHOOK？

有任何想法吗？

<receiver android:name=".IncomingBroadcastReceiver">                     
        <intent-filter>                                                   
            <action android:name="android.intent.action.PHONE_STATE"/>   
        </intent-filter>
    </receiver> 



public class IncomingBroadcastReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
    // If an incoming call arrives
    if (state.equals(TelephonyManager.EXTRA_STATE_RINGING))
    { //Did my work }

我试图知道当被叫者举起电话时如何提醒.我已经使用PhoneStateListener 沿BroadcastReceiver.

一般来说它有三种状态CALL_STATE_IDLE , CALL_STATE_OFFHOOK, CALL_STATE_RINGING.

CALL_STATE_OFFHOOK 当呼叫连接时状态正在呼叫,在被呼叫者应答呼叫之后没有呼叫上述三种状态的状态.

这是我的BroadcastReceiver.

public class PhoneStateBroadcastReceiver extends BroadcastReceiver
{

   @Override
    public void onReceive(Context context, Intent intent)
    {

        TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        telephonyManager.listen(new CustomPhoneStateListener(context), PhoneStateListener.LISTEN_CALL_STATE);

    }

    public class CustomPhoneStateListener  extends PhoneStateListener
    {

        Context context; //Context to make Toast if required 
        ActivityManager activityManager;

        public CustomPhoneStateListener(Context context)
        {
            super();
            this.context = context;
        }

        @Override
        public void onCallStateChanged(int state, String incomingNumber) 
        {
            super.onCallStateChanged(state, incomingNumber);
            Log.v("PhoneStateBroadcastReceiver", "onCallStateChanged state"+state);


            switch (state) 
            {
            case TelephonyManager.CALL_STATE_IDLE: …

假设我们在我们的手机上录制了文件,当我们打电话给任何人时,一旦他接到电话他应该听录音的语音文件,我们已经记录了我已经通过下面提到的链接仍然问题仍然存在 如何玩呼叫开始时的音频文件？ http://youropensource.com/projects/532-access-the-incoming-outgoing-calls-using-TelephonyManager 我试过,但我现在没办法解决我必须做的事情？
