关于百度地图的基础地图和定位功能

在AndroidManifest.xml中写入密匙和权限:

在两个Fragment上写入，进行切换:

显示基础地图：

package com.bwie.fragments;import com.baidu.mapapi.SDKInitializer;import com.baidu.mapapi.map.MapView;import com.bwie.test.R;import android.os.Bundle;import android.support.v4.app.Fragment;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;public class BasemapFragment extends Fragment{private MapView mMapView =null;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {//注意该方法要再setContentView方法之前实现          SDKInitializer.initialize(getActivity().getApplicationContext()); View view=inflater.inflate(R.layout.base_map_fragment_item, null);//获取地图控件引用          mMapView = (MapView) view.findViewById(R.id.bmapView); return view;}@Overridepublic void onDestroy() {          super.onDestroy();          //在activity执行onDestroy时执行mMapView.onDestroy()，实现地图生命周期管理          mMapView.onDestroy();      }      @Overridepublic void onResume() {          super.onResume();          //在activity执行onResume时执行mMapView. onResume ()，实现地图生命周期管理          mMapView.onResume();          }      @Overridepublic void onPause() {          super.onPause();          //在activity执行onPause时执行mMapView. onPause ()，实现地图生命周期管理          mMapView.onPause();      }}

在Activity中进行切换：

package com.bwie.test;import com.bwie.fragments.BasemapFragment;import com.bwie.fragments.LocationUserFragment;import android.os.Bundle;import android.app.Activity;import android.graphics.Color;import android.support.v4.app.FragmentActivity;import android.support.v4.app.FragmentManager;import android.support.v4.app.FragmentTransaction;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.LinearLayout;public class MainActivity extends FragmentActivity implements OnClickListener{private LinearLayout ll;private Button base;private Button location;private FragmentManager fm;private BasemapFragment basemap;private LocationUserFragment locationuser;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);fm=getSupportFragmentManager();init();}private void init() {//找对象ll=(LinearLayout)findViewById(R.id.ll);base=(Button)findViewById(R.id.bt_base);location=(Button)findViewById(R.id.bt_location);//实例化basemap=new BasemapFragment();locationuser=new LocationUserFragment();//创建事务FragmentTransaction trac=fm.beginTransaction();trac.add(R.id.ll, basemap);trac.add(R.id.ll, locationuser);trac.replace(R.id.ll, basemap);trac.commit();//按钮的背景色base.setBackgroundColor(Color.BLUE);location.setBackgroundColor(Color.GRAY);//按钮的监听base.setOnClickListener(this);location.setOnClickListener(this);}@Overridepublic void onClick(View v) {switch (v.getId()) {case R.id.bt_base:base.setBackgroundColor(Color.BLUE);location.setBackgroundColor(Color.GRAY); FragmentTransaction trac=fm.beginTransaction();trac.replace(R.id.ll, basemap);trac.commit();break;case R.id.bt_location:base.setBackgroundColor(Color.GRAY);location.setBackgroundColor(Color.BLUE); FragmentTransaction trac1=fm.beginTransaction();trac1.replace(R.id.ll, locationuser);trac1.commit();break;default:break;}}}

另外百度地图的jar包也一定要添加进去。
