利用百度地图Android SDK 进行模糊地理位置的查询_百度地图sdk 模糊定位

今天学习了一个百度的安卓api。调试了一个程序，主要是根据一个关键字，搜可能存在的地理位置。

主要用到了这2个类：SuggestionSearch和OnGetSuggestionResultListener 返回结果是用SuggestionResult和SuggestionInfo

关于这几个类的详细说明：大家请参考百度给的官方文档，都是中文 ，翻下很快。

MainActivity

具体代码如下：

package com.example.fuzzynamesearch;
 
import java.util.List;
 
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;
 
import com.baidu.mapapi.SDKInitializer;
import com.baidu.mapapi.map.MapView;
import com.baidu.mapapi.search.sug.OnGetSuggestionResultListener;
import com.baidu.mapapi.search.sug.SuggestionResult;
import com.baidu.mapapi.search.sug.SuggestionResult.SuggestionInfo;
import com.baidu.mapapi.search.sug.SuggestionSearch;
import com.baidu.mapapi.search.sug.SuggestionSearchOption;
 
public class MainActivity extends ActionBarActivity {
//MapView mMapView = null;
	//TextView tv=null;
	SuggestionSearch mSuggestionSearch;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		 SDKInitializer.initialize(getApplicationContext());  
	        setContentView(R.layout.activity_main);  
	      //  mMapView = (MapView) findViewById(R.id.bmapView);
	        mSuggestionSearch = SuggestionSearch.newInstance();
	      //  tv= (TextView) findViewById(R.id.editText1);
	        mSuggestionSearch.setOnGetSuggestionResultListener(listener);
	        mSuggestionSearch.requestSuggestion((new SuggestionSearchOption())  
	        	    .keyword("同济大学")  
	        	    .city("上海"));
	}
 
	
	OnGetSuggestionResultListener listener = new OnGetSuggestionResultListener() {  
	    public void onGetSuggestionResult(SuggestionResult res) {  
	        if (res == null || res.getAllSuggestions() == null) {  
	            return;  
	            //未找到相关结果  
	        }else
	        {
	        	List<SuggestionInfo> resl=res.getAllSuggestions();
	        	for(int i=0;i<resl.size();i++)
	        	{
	        		Log.i("result: ","city"+resl.get(i).city+" dis "+resl.get(i).district+"key "+resl.get(i).key);
	        
	        	}
	        }
	    //获取在线建议检索结果  
	    }  
	};
	
	
	@Override  
    protected void onDestroy() {  
		mSuggestionSearch.destroy();
	//	mMapView.onDestroy();
        super.onDestroy();  
        //在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理  
        
 
    }  
    @Override  
    protected void onResume() {  
 //   	mMapView.onResume(); 
        super.onResume();  
        //在activity执行onResume时执行mMapView. onResume ()，实现地图生命周期管理  
         
        }  
    @Override  
    protected void onPause() { 
   // 	mMapView.onPause();
        super.onPause();  
        //在activity执行onPause时执行mMapView. onPause ()，实现地图生命周期管理  
        ;  
        }  
	
	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}
 
	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		// Handle action bar item clicks here. The action bar will
		// automatically handle clicks on the Home/Up button, so long
		// as you specify a parent activity in AndroidManifest.xml.
		int id = item.getItemId();
		if (id == R.id.action_settings) {
			return true;
		}
		return super.onOptionsItemSelected(item);
	}
}

libs文件夹下要防这几个文件

结果是这样的:
