        //必须回掉mapview的oncreat方法
        mapView.onCreate(savedInstanceState);
        mapView.onResume();

                    GeocodeSearch geocodeSearch=new GeocodeSearch(AdressActivity.this);
                    geocodeSearch.setOnGeocodeSearchListener(AdressActivity.this);
                    GeocodeQuery query=new GeocodeQuery(editText.getText().toString(),"010");
                    //将中文转换为地址编码
                    geocodeSearch.getFromLocationNameAsyn(query);
                }
            }
        });

    }

//在onCreat方法中给aMap对象赋值
setContentView(R.layout.basicmap_activity);
