Solution

Well, It's very easy just add the code below inside your myPhoneStateChangeListener's onCallStateChanged method

if(TelephonyManager.CALL_STATE_OFFHOOK==state) {
    // phone picked up
}
if(TelephonyManager.CALL_STATE_IDLE==state) {
    // either phone hanged up or ringing stopped
}

or you can refer to this solution

Alternatively, You can also use BroadcastReciever to check the state change.

public class PhoneStateReceiver extends BroadcastReceiver {

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

        assert bundle != null;
        String phoneState = bundle.getString(TelephonyManager.EXTRA_STATE);
        Log.d("phoneCallReceiver", phoneState);

        if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_IDLE)) {
            Log.d("phoneCallReceiver", "phone hanged up");
        }
        if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            Log.d("phoneCallReceiver", "phone picked up");
        }
        if (phoneState.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
            Log.d("phoneCallReceiver", "phone ringing");
        }
    }
}
