android SDK V4和V7冲突？ 首先在app下的build.gradle文件中删除provided files('libs/android-support-v4.jar')或者通过File菜单下的Project Structure中的app模块中的Dependencies选项删除。然后在工程libs目录下删除android-support-v4.jar文件。
工程运行后报TTSController初始化失败？ 我的做法是把libs中的so库全部copy出来，放在jniLibs文件夹中，jniLibs是自己创建的，跟libs在同一层目录下(其它目录也可以)，然后在build.gradle中声明下，以下这段语句放在android标签下即可
sourceSets {
main {
jniLibs.srcDirs = ['jniLibs']
}
}
大功告成，来张图秀一下
private LocationManagerProxy mLocationManager;
private AMapLocationListener mLocationListener = new AMapLocationListener() {
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
}
@Override
public void onLocationChanged(AMapLocation location) {
if (location != null && location.getAMapException().getErrorCode() == 0) {
Log.e(TAG, "GPS: " + location.getLatitude() + "," + location.getLongitude());
LatLng latLng = new LatLng(mStartPoint.getLatitude(), mStartPoint.getLongitude());
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title("您当前的位置");
mAmap.addMarker(markerOptions);
mAmap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 12));
} else {
showToast("定位出现异常,请检查网络连接.");
mGPSProgressDialog.dismiss();
//以上海市人民政府为中心显示定位时出错的初始地图
LatLng latLng = new LatLng(31.230429, 121.473709);
mAmap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, 12));
}
}
};
mLocationManager = LocationManagerProxy.getInstance(this);
mLocationManger.requestLocationData(LocationProviderProxy.AMapNetwork, -1, 15, mLocationListener);应用场景一般是这样的: 在输入框中输入关键字如"东方明珠",系统则提供所有跟"东方明珠"相关的地址信息供用户选择。以下代码是在一个输入框中输入一字符串，经过查询POI Search将相关结果返回，以listview的形式显示出来，经用户点击后将具体的信息写入到输入框中。原来项目需要，这里还记录了对应地址的经纬度数据。
//输入框是一个EditText
mEndPointText.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
String newText = s.toString().trim();
PoiSearch.Query query = new PoiSearch.Query(newText, "", "021");
query.setPageSize(10);
query.setPageNum(1);
PoiSearch poiSearch = new PoiSearch(NaviStartActivity.this, query);
poiSearch.setOnPoiSearchListener(new PoiSearch.OnPoiSearchListener() {
@Override
public void onPoiSearched(PoiResult poiResult, int i) {
if (i == 0) {
for (int j = 0; j < poiResult.getPois().size(); j++) {
if (!poiResult.getPois().get(j).getSnippet().isEmpty()) {
poiAddressList.add(poiResult.getPois().get(j).getSnippet());
poiLatLonList.add(poiResult.getPois().get(j).getLatLonPoint());
}
}
poiAddressArray = new String[poiAddressList.size()];
poiAddressArray = poiAddressList.toArray(poiAddressArray);
poiLatLngArray = new LatLonPoint[poiLatLonList.size()];
poiLatLngArray = poiLatLonList.toArray(poiLatLngArray);
adapterTextview_poi_result = new AdapterTextview(NaviStartActivity.this, poiAddressArray);
listView_poi_result.setAdapter(adapterTextview_poi_result);
adapterTextview_poi_result.notifyDataSetChanged();
poiAddressList.clear();
poiLatLonList.clear();
}
}
@Override
public void onPoiItemDetailSearched(PoiItemDetail poiItemDetail, int i) {
}
});
listView_poi_result.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
mEndPoints.clear();
mEndPointText.setText(poiAddressArray[position]);
mEndPoint = new NaviLatLng(poiLatLngArray[position].getLatitude(), poiLatLngArray[position].getLongitude());
mEndPoints.add(mEndPoint);
}
});
poiSearch.searchPOIAsyn();
}
@Override
public void afterTextChanged(Editable s) {
}
});地理编码，通俗来讲就是将具体的地址(如xx区xx路)转换成经纬度数据，来看代码
GeocodeSearch geocodeSearch = new GeocodeSearch(this);
geocodeSearch.setOnGeocodeSearchListener(new GeocodeSearch.OnGeocodeSearchListener() {
@Override
public void onRegeocodeSearched(RegeocodeResult regeocodeResult, int i) {
//逆地理编码，经纬度转换成地址
}
@Override
public void onGeocodeSearched(GeocodeResult geocodeResult, int i) {
//地理编码，地址转换成经纬度
if (i == 0) {
if (geocodeResult != null && geocodeResult.getGeocodeAddressList() != null && geocodeResult.getGeocodeAddressList().size() > 0) {
GeocodeAddress geocodeAddress = geocodeResult.getGeocodeAddressList().get(0);
Log.e(TAG, "destination position: " + geocodeAddress.getLatLonPoint());
}
} else {
Toast.makeText(NaviStartActivity.this, "该地址不存在!", Toast.LENGTH_SHORT).show();
}
}
});
//以上海地区地址的查询为例,城市代码可以查看高德的文档
GeocodeQuery geocodeQuery = new GeocodeQuery(address, "021");
geocodeSearch.getFromLocationNameAsyn(geocodeQuery);
