错误充气类片段mapfragment V2

Question

我收到以下错误的Android 4.4.4导致崩溃，但它是在工作的Andriod 5.0.1完美

我对下面的Java类

载入地图

public class MapActivity extends Activity implements OnMapReadyCallback { 

    double longitude, latitude; 
    TextView m_tvNo, m_tvYes; 
    public static String m_Name, m_Location; 
    DBParse m_DBparser; 
    Context m_cont; 
    private LocationManager locationManager; 
    private GoogleMap googleMap; 
    Circle mapCircle; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.add_search_location_dialog_map); <<----in this line I am getting an error 

下面是

<fragment 
     android:id="@+id/map" 
     android:name="com.google.android.gms.maps.MapFragment" 
     android:layout_width="match_parent" 
     android:layout_height="@dimen/map_height" /> 

我得到以下错误XML代码

公共类MapActivity扩展它扩展FragmentActivity实现OnMapReadyCallback {

已扩展其作为活动唯一

Answer 2

我已经只把超解决这个问题第一个

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     setContentView(R.layout.add_search_location_dialog_map);
