在谷歌地图Android的搜索栏 [英] search bar in google map android

问题描述

如何在谷歌地图使用的是Android的MapView对象添加​​一个搜索栏？

 公共无效的onCreate（捆绑savedInstanceState）
{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.mapmain）;
    图形页面=（图形页面）findViewById（R.id.mapView）;
    的LinearLayout zoomLayout =（的LinearLayout）findViewById（R.id.zoom）;
    查看ZOOMVIEW = mapView.getZoomControls（）;    zoomLayout.addView（ZOOMVIEW，
        新LinearLayout.LayoutParams（
            LayoutParams.WRAP_CONTENT，
            LayoutParams.WRAP_CONTENT））;
    mapView.displayZoomControls（真）;}
 

解决方案

假设你有一个叫做一个EditText：mapSearchBox

  mapSearchBox =（EditText上）findViewById（R.id.search）;
    mapSearchBox.setOnEditorActionListener（新TextView.OnEditorActionListener（）{
        公共布尔onEditorAction（TextView的V，INT actionId，KeyEvent的事件）{
             如果（actionId == || EditorInfo.IME_ACTION_SEARCH
                    actionId == || EditorInfo.IME_ACTION_DONE
                    actionId == || EditorInfo.IME_ACTION_GO
                    event.getAction（）== KeyEvent.ACTION_DOWN＆放大器;＆放大器;
                    event.getKey code（）== KeyEvent.KEY code_ENTER）{                //隐藏虚拟键盘
                InputMethodManager IMM =（InputMethodManager）getSystemService（Context.INPUT_METHOD_SERVICE）;
                imm.hideSoftInputFromWindow（mapSearchBox.getWindowToken（），0）;                新SearchClicked（mapSearchBox.getText（）的toString（）。）的execute（）。
                mapSearchBox.setText（，TextView.BufferType.EDITABLE）;
                返回true;
            }
            返回false;
        }
    }）;
 

然后，你需要的SearchClicked类来处理请求：

 私有类SearchClicked扩展的AsyncTask＆LT;太虚，太虚，布尔＆GT; {
        私人字符串toSearch;
        私有地址地址;        公共SearchClicked（字符串toSearch）{
            this.toSearch = toSearch;
        }        @覆盖
        保护布尔doInBackground（虚空......空隙）{            尝试{
                地理codeR地理codeR =新的地缘codeR（getApplicationContext（），Locale.UK）;
                清单＆LT;地址＆gt;结果=地理coder.getFromLocationName（toSearch，1）;                如果（results.size（）== 0）{
                    返回false;
                }                地址= results.get（0）;                  //现在做这个的GeoPoint的东西：
                GeoPoint的P =新的GeoPoint（（INT）（address.getLatitude（）* 1E6），（INT）（address.getLongitude（）* 1E6））            }赶上（例外五）{
                Log.e（，出事了，E）;
                返回false;
            }
            返回true;
        }
}
 

How can I add a search bar in Google map using MapView object of Android?

    public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mapmain);


    mapView = (MapView) findViewById(R.id.mapView);
    LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom);  
    View zoomView = mapView.getZoomControls(); 

    zoomLayout.addView(zoomView, 
        new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, 
            LayoutParams.WRAP_CONTENT)); 
    mapView.displayZoomControls(true);

}

解决方案

Assuming you have an EditText called: mapSearchBox

mapSearchBox = (EditText) findViewById(R.id.search);
    mapSearchBox.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
             if (actionId == EditorInfo.IME_ACTION_SEARCH ||
                    actionId == EditorInfo.IME_ACTION_DONE ||
                    actionId == EditorInfo.IME_ACTION_GO ||
                    event.getAction() == KeyEvent.ACTION_DOWN &&
                    event.getKeyCode() == KeyEvent.KEYCODE_ENTER) {

                // hide virtual keyboard
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(mapSearchBox.getWindowToken(), 0);

                new SearchClicked(mapSearchBox.getText().toString()).execute();
                mapSearchBox.setText("", TextView.BufferType.EDITABLE);
                return true;
            }
            return false;
        }
    });

Then you need the 'SearchClicked' class to handle the request:

   private class SearchClicked extends AsyncTask<Void, Void, Boolean> {
        private String toSearch;
        private Address address;

        public SearchClicked(String toSearch) {
            this.toSearch = toSearch;
        }

        @Override
        protected Boolean doInBackground(Void... voids) {

            try {
                Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.UK);
                List<Address> results = geocoder.getFromLocationName(toSearch, 1);

                if (results.size() == 0) {
                    return false;
                }

                address = results.get(0);

                  // Now do something with this GeoPoint:
                GeoPoint p = new GeoPoint((int) (address.getLatitude() * 1E6), (int) (address.getLongitude() * 1E6))

            } catch (Exception e) {
                Log.e("", "Something went wrong: ", e);
                return false;
            }
            return true;
        }
}
