易采站长站为您分析Android百度地图实现搜索和定位及自定义图标绘制并点击时弹出泡泡的相关资料,需要的朋友可以参考下
一、问题描述
上一次我们使用百度地图实现基本的定位功能，接下来我们继续实现搜索和定位，并使用LocationOverlay绘制定位位置，同时展示如何使用自定义图标绘制并点击时弹出泡泡
如图所示：
二、编写MyApplication类
public class MyApplication extends Application {
private static MyApplication mInstance = null;
public boolean m_bKeyRight = true;
public BMapManager mBMapManager = null;
public static final String strKey = "申请的应用key";
@Override
public void onCreate() {
super.onCreate();
mInstance = this;
initEngineManager(this);
}
public void initEngineManager(Context context) {
if (mBMapManager == null) {
mBMapManager = new BMapManager(context);
}
if (!mBMapManager.init(strKey,new MyGeneralListener())) {
Toast.makeText(MyApplication.getInstance().getApplicationContext(), "BMapManager 初始化错误!", Toast.LENGTH_LONG).show();
}
}
public static MyApplication getInstance() {
return mInstance;
}
// 常用事件监听，用来处理通常的网络错误，授权验证错误等
public static class MyGeneralListener implements MKGeneralListener {
@Override
public void onGetNetworkState(int iError) {
if (iError == MKEvent.ERROR_NETWORK_CONNECT) {
Toast.makeText(MyApplication.getInstance().getApplicationContext(), "您的网络出错啦！",Toast.LENGTH_LONG).show();
}else if (iError == MKEvent.ERROR_NETWORK_DATA) {
Toast.makeText(MyApplication.getInstance().getApplicationContext(), "输入正确的检索条件！",Toast.LENGTH_LONG).show();
}
}
@Override
public void onGetPermissionState(int iError) {
//非零值表示key验证未通过
if (iError != 0) {
//授权Key错误：
Toast.makeText(MyApplication.getInstance().getApplicationContext(),
"请在 DemoApplication.java文件输入正确的授权Key,并检查您的网络连接是否正常！error: "+iError, Toast.LENGTH_LONG).show();
MyApplication.getInstance().m_bKeyRight = true;
}
else{
MyApplication.getInstance().m_bKeyRight = true;
//Toast.makeText(DemoApplication.getInstance().getApplicationContext(), "key认证成功", Toast.LENGTH_LONG).show();
}
}
}
}
