没有在地图中搜索到的地方 [英] not getting searched place in maps
本文介绍了没有在地图中搜索到的地方的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在Google地图上工作。该应用程序成功跟踪用户的位置，但是当我搜索的地方它不会返回结果。下面是我的代码以及manifest和gradle.build。
还附加了logcat，确认地理定位功能在地理定位显示时执行。但没有地方返回。
MapsActivity.java
@Override
保护void onCreate（Bundle savedInstanceState）{
super .onCreate（savedInstanceState）;
setContentView（R.layout.activity_maps）;
mSearchText =（EditText）findViewById（R.id.input_search）;
mGps =（ImageView）findViewById（R.id.gps_ic）;
mSearchText.setOnEditorActionListener（new TextView.OnEditorActionListener（）{
@Override
public boolean onEditorAction（TextView textView，int actionId，KeyEvent keyEvent） {
if（actionId == EditorInfo.IME_ACTION_SEARCH
|| actionId == EditorInfo.IME_ACTION_DONE
|| keyEvent.getAction（）== KeyEvent.ACTION_DOWN
|| keyEvent.getAction （）== KeyEvent.KEYCODE_ENTER）{
//执行我们的搜索
的方法geoLocate（）;
返回true;
}
返回false;
}
}）;
private void geoLocate（）{
Log.d（TAG，geoLocate：geolocating）;
String searchString = mSearchText.getText（）。toString（）;
Geocoder geocoder =新的地理编码器（MapsActivity.this）;
列表<地址> list = new ArrayList<>（）;
尝试{
Toast.makeText（MapsActivity.this，searchString，Toast.LENGTH_SHORT）.show（）;
list = geocoder.getFromLocationName（searchString，1）;
} catch（IOException e）{
Log.e（TAG，geoLocate：IOException：+ e.getMessage（））;
}
if（list.size（）> 0）{
Address address = list.get（0）;
Log.d（TAG，geoLocate：found a location：+ address.toString（））;
//Toast.makeText（this，address.toString（），Toast.LENGTH_SHORT）.show（）;
$ b $ moveCamera（new LatLng（address.getLatitude（），address.getLongitude（）），DEFAULT_ZOOM，
address.getAddressLine（0））;

使用
Google地图Android API v2时不需要ACCESS_COARSE / FINE_LOCATION权限，但您必须指定粗略或精细的
位置'MyLocation'功能的权限。

Google Maps API API密钥定义为字符串资源。
（请参阅文件res / values / google_maps_api.xml）。
请注意，API密钥已链接到用于签署APK的加密密钥。
您需要为每个加密密钥使用不同的API密钥，包括用于
签名的发布密钥。
您可以在src / debug /和src / release /中定义调试和发布目标的键。

解决方案您需要使用纬度经度
为搜索文本搜索纬度经度，您需要实现 Google Place Autocomplete
或从文本搜索
private void geoLocate（）{
final String searchString = mSearchText.getText（）。toString（）;
final Geocoder geocoder = new Geocoder（SetLocationMapActivity.this）;
新线程（new Runnable（）{
@Override
public void run（）{
try {
List< Address> addressList = geocoder.getFromLocationName（searchString，1）;
if（addressList！= null&& addressList.size（）> 0）{
final String locality = addressList.get（0）。 getAddressLine（0）;
final String country = addressList.get（0）.getCountryName（）;
$ b $ final地址= addressList.get（0）;
if（！locality.isEmpty（）&&！country.isEmpty（））{
try {
runOnUiThread（new Runnable（）{
@Override
public void run（）{
Log.e（tag，address =+ locality ++ country）;
moveCamera（new LatLng（address.getLatitude（），address.getLongitude（）），DEFAULT_ZOOM，
address.getAddressLine（0））;
}
}）;
Thread.sleep（300）;
} catch（InterruptedException e）{
e.printStackTrace（）;
$ catch（IOException e）{
e.printStackTrace（）;
}
}
}）。start（）;
}
或从纬度经度搜索
更改此行
列表<地址> addressList = geocoder.getFromLocation（latLng.latitude，latLng.longitude，1）;
i am working on google maps. the app sucesssfully trace user location but when i search for place it doesn't return a result. below is my code along with manifest and gradle.build.
Also logcat is also attached which confirms the geolocate function execute as geolocating is displayed. but no place is returned.
MapsActivity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
mSearchText = (EditText) findViewById(R.id.input_search);
mGps = (ImageView) findViewById(R.id.gps_ic);
mSearchText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
if(actionId == EditorInfo.IME_ACTION_SEARCH
|| actionId == EditorInfo.IME_ACTION_DONE
|| keyEvent.getAction() == KeyEvent.ACTION_DOWN
|| keyEvent.getAction() == KeyEvent.KEYCODE_ENTER){
//execute our method for searching
geoLocate();
return true;
}
return false;
}
});
}
private void geoLocate(){
Log.d(TAG, "geoLocate: geolocating");
String searchString = mSearchText.getText().toString();
Geocoder geocoder = new Geocoder(MapsActivity.this);
List<Address> list = new ArrayList<>();
try{
Toast.makeText(MapsActivity.this, searchString, Toast.LENGTH_SHORT).show();
list = geocoder.getFromLocationName(searchString, 1);
}catch (IOException e){
Log.e(TAG, "geoLocate: IOException: " + e.getMessage() );
}
if(list.size() > 0){
Address address = list.get(0);
Log.d(TAG, "geoLocate: found a location: " + address.toString());
//Toast.makeText(this, address.toString(), Toast.LENGTH_SHORT).show();
moveCamera(new LatLng(address.getLatitude(), address.getLongitude()), DEFAULT_ZOOM,
address.getAddressLine(0));
}
}

解决方案 you need to search place using Latitude Longitude
for search text to Latitude Longitude you need to implement Google Place Autocomplete
OR search from text
private void geoLocate() {
final String searchString = mSearchText.getText().toString();
final Geocoder geocoder = new Geocoder(SetLocationMapActivity.this);
new Thread(new Runnable() {
@Override
public void run() {
try {
List<Address> addressList = geocoder.getFromLocationName(searchString, 1);
if (addressList != null && addressList.size() > 0) {
final String locality = addressList.get(0).getAddressLine(0);
final String country = addressList.get(0).getCountryName();
final Address address = addressList.get(0);
if (!locality.isEmpty() && !country.isEmpty()) {
try {
runOnUiThread(new Runnable() {
@Override
public void run() {
Log.e("tag", "address=" + locality + " " + country);
moveCamera(new LatLng(address.getLatitude(), address.getLongitude()), DEFAULT_ZOOM,
address.getAddressLine(0));
}
});
Thread.sleep(300);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
}).start();
}
OR search from Latitude Longitude
change this line
List<Address> addressList = geocoder.getFromLocation(latLng.latitude, latLng.longitude, 1);
