從Lat長度轉移到NMEA數據包

我正在從lat long項目中添加簡單的NMEA，Lat很長時間地工作，但是當轉移到nmea時，它給了我錯誤。從Lat長度轉移到NMEA數據包

如果有人能幫助我，我會很感激你。

protected LocationManager locationManager; 
protected Button retrieveLocationButton; 

@Override 
public void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    retrieveLocationButton = (Button) findViewById(R.id.retrieve_location_button); 

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 

    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,2000,0,this); 
    locationManager.addNmeaListener(this); 

    retrieveLocationButton.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      showCurrentLocation(); 
     } 
    });  
}  



protected void showCurrentLocation() { 
     // TODO Auto-generated method stub 

    } 

    @SuppressWarnings("unused") 
    private class MyLocationListener implements NmeaListener { 

    public void onLocationChanged(Location location) { 
     String message = String.copyValueOf(null); 

     locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,this); 

     boolean isGood = locationManager.addNmeaListener((NmeaListener) this); 

     Toast.makeText(MainActivity.this, message, Toast.LENGTH_LONG).show(); 
    } 

    public void onStatusChanged(String s, int i, Bundle b) { 
     Toast.makeText(MainActivity.this, "Provider status changed", 
       Toast.LENGTH_LONG).show(); 
    } 

    public void onProviderDisabled(String s) { 
     Toast.makeText(MainActivity.this, 
       "Provider disabled by the user. GPS turned off", 
       Toast.LENGTH_LONG).show(); 
    } 

    public void onProviderEnabled(String s) { 
     Toast.makeText(MainActivity.this, 
       "Provider enabled by the user. GPS turned on", 
       Toast.LENGTH_LONG).show(); 
    } 

    } 

}

什麼錯誤？你需要給我們一個跡象，說明我們可以如何幫助 –

每次我在修改nmea之後運行代碼強制關閉， – user1749938

你真的不提供足夠的信息有關的「錯誤」，但在我看來，下面一行將導致編譯時錯誤...

locationManager.addNmeaListener(this);

試着改變它..

locationManager.addNmeaListener(new MyLocationListener());

其實我每次運行代碼強制關閉， – user1749938

我已經更改爲下面但相同問題的應用程序開始關閉 LocationManager locationmanager; locationManager =（LocationManager）getSystemService（LOCATION_SERVICE）; locationManager.addNmeaListener（新NmeaListener（）{ \t公共無效onNmeaReceived（長時間戳，字符串NMEA）{ Log.d（TAG，「接收到的NMEA：」）; Log.d（TAG，「時間戳是：」 + timestamp +「nmea is：」+ nmea）; }}）; – user1749938
