怎么说来电者姓名不是来电号码？

Question

这是我的主要活动代码..一切都很好，但它说来电号码不是来电者姓名。

public class MainActivity extends Activity implements TextToSpeech.OnInitListener {
    private TextToSpeech tts;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tts = new TextToSpeech(this, this);

        TelephonyManager telephonyManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

        PhoneStateListener callStateListener = new PhoneStateListener() {
            public void onCallStateChanged(int state, String incomingNumber){
                if(state==TelephonyManager.CALL_STATE_RINGING){
                    tts.speak(incomingNumber+" calling", TextToSpeech.QUEUE_FLUSH, null);
                    Toast.makeText(getApplicationContext(),"Phone is Ringing : "+incomingNumber, Toast.LENGTH_LONG).show();
                }
                if(state==TelephonyManager.CALL_STATE_OFFHOOK){
                    Toast.makeText(getApplicationContext(),"Phone in a call or call picked", Toast.LENGTH_LONG).show();
                }
                if(state==TelephonyManager.CALL_STATE_IDLE){
                    //Toast.makeText(getApplicationContext(),"phone is neither ringing nor in a call", Toast.LENGTH_LONG).show();
                }
            }
        };
        telephonyManager.listen(callStateListener,PhoneStateListener.LISTEN_CALL_STATE);
    }

    @Override
    public void onInit(int status) {
        if (status == TextToSpeech.SUCCESS) {
            int result = tts.setLanguage(Locale.US);
            if (result == TextToSpeech.LANG_MISSING_DATA
                    || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                Log.e("TTS", "This Language is not supported");
            } else {
            }

        } else {
            Log.e("TTS", "Initilization Failed!");
        }
    }

    @Override
    public void onDestroy() {
        // Don't forget to shutdown tts!
        if (tts != null) {
            tts.stop();
            tts.shutdown();
        }
        super.onDestroy();
    }

一切都很好，但它说来电号码不是来电者姓名

您需要在用户联系人中查找语音，以查看是否有任何记录匹配。
