Question

我想用我的程序拨打电话，然后识别通话状态。我想检测传出铃声的结束。

如何检测传出铃声的结束？

我使用Flowing代码进行make调用。

EditText ed = (EditText) findViewById(R.id.txtcall);        
Uri uri = Uri.fromParts("tel", ed.getText().toString(), null);
callIntent = new Intent(Intent.ACTION_CALL,uri);
startActivity(callIntent);

以下代码段可以帮助您找到电话当前雕像，无论是拾取，响铃还是闲置。您可以轻松使用这些状态并相应地实现您的功能。

 private class CustomPhoneStateListener extends PhoneStateListener
 {        
            @Override
            public void onCallStateChanged(int state, String incomingNumber) 
            {
                super.onCallStateChanged(state, incomingNumber);

                //TelephonyManager.CALL_STATE_IDLE
                //TelephonyManager.CALL_STATE_OFFHOOK
                //TelephonyManager.CALL_STATE_RINGING
            }
 }

通过以下方式检查： - 您将能够呼叫用户

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:+9189745847"));
startActivity(callIntent);

并且还在androidmanifest.xml文件中使用：

 <uses-permission android:name="android.permission.CALL_PHONE" />

查看意图NEW_OUTGOING_CALL

 <receiver android:name=".receiver.OutgoingCallReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

然后您可以使用PhoneStateListener检查调用状态：

public class OutgoingCallReceiver extends BroadcastReceiver {

protected static final String CLASS_TAG = "OutgoingCallReceiver : ";

@Override
public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();
    if(null == bundle) return;

    String phonenumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
    Log.i(LOG_TAG, CLASS_TAG + "phone number " + phonenumber);

        final TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        tm.listen(new PhoneStateListener() {
            @Override
            public void onCallStateChanged(int state, String incomingNumber) {
                switch (state) {
                case TelephonyManager.CALL_STATE_RINGING:
                    Log.d(LOG_TAG, CLASS_TAG + "RINGING");
                    break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                    Log.d(LOG_TAG, CLASS_TAG + "OFFHOOK");
                    Process.onCallStateIsOFFHOOK();
                    break;
                case TelephonyManager.CALL_STATE_IDLE:
                    Process.onCallStateIsIDLE();
                    Log.d(LOG_TAG, CLASS_TAG + "IDLE");
                    break;
                default:
                    Log.d(LOG_TAG, CLASS_TAG + "Default: " + state);
                    break;
                }
            }
        }, PhoneStateListener.LISTEN_CALL_STATE);
    }
}

在Process类中，您可以通过录制VOICE_CALL来检测铃声并创建更多状态，如CALLBEGINS，CALLANSWERED。 onCallStateIsIDLE（）的示例：

public void onCallStateIsIDLE() {
    setSpeakingOn(false);
    if (stateCall == STATE_CALLANSWERED ||
            stateCall == STATE_CALLBEGINS ||
            stateCall == STATE_DIALISOFFHOOK ||
            stateCall == STATE_DIALENDREQUESTED) {
        Log.i(LOG_TAG, CLASS_TAG + " - forcing state : STATE_DIALREADY : old state = " + stateCall);
        stateCall = STATE_DIALREADY;
    }
}
