在我的应用程序中，我有一个 activity，您可以在其中根据您在 edittext 中键入的地址在地图中固定位置，或者您可以移动它出现在 onMapReady 函数中的固定位置。
我的 activity 的布局有显示地图的片段，一个按钮 return 关于前一个 activity 中图钉位置的信息和一个编辑文本输入地址并按下按钮，地图上的前一个图钉将被删除，并出现一个包含您输入的位置的新图钉（如果存在）。
-- 这是我的 onMapReady 函数，它在搜索按钮中有一个侦听器并初始化图钉和拖动它后获取图钉位置的函数：

map.animateCamera(zoom);
map.addMarker(new MarkerOptions()
.title("Shop")
.snippet("Is this the right location?")
.position(position))
.setDraggable(true);
// map.setInfoWindowAdapter(new PopupAdapter(getLayoutInflater()));
map.setOnInfoWindowClickListener(this);

ImageButton search = (ImageButton) findViewById(R.id.search);
final EditText searchaddress = (EditText) findViewById(R.id.locationsearch);
final int[] numAttempts = {0};

直到几天前，我可以从用户在编辑文本中使用上述代码键入的位置显示一个图钉。现在，由于未知原因，我无法再使用完全相同的代码来执行此操作。
总是显示toast关于'Wrong Address. Please try another one!'，即使我在编辑文本中输入的地址存在，geoResults的大小总是0并且没有Logcat
出现异常

(SIGABRT) at 0x000008d2 (code=0), thread 12386 (uide_me_for_all) ,
我不知道括号中的这个东西是什么，但我的包名称是 guide_me_for_all 而不是 uide_me_for_all。 （以防与此有关）
如果有人能帮我看看以上是什么意思，我将不胜感激。
修改以上代码后更新：
从 class 到前一个 activity 到 return 位置的代码（未解决 - 总是得到 NULL 值）：
在class中：
@Override
protected void onPostExecute(LatLng result) {
Log.i("GEOCODE", result.toString());
Intent i = new Intent(this.mainContxt , MapsActivity.class );
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra( "latlng" , result );
this.mainContxt.startActivity(i);
super.onPostExecute(result);
}
在 MapsActivity 的 onCreate 中，我有这个：
if (getIntent() != null) {
Intent intent = getIntent();null){
position_from_address = intent.getStringExtra("latlng");
}
然后在我的 activity 的搜索按钮的 onClickListener 中，我得到这样的位置：
if (position_from_address != null){
String[] latlong = position_from_address.split(",");
double latitude = Double.parseDouble(latlong[0]);
double longitude = Double.parseDouble(latlong[1]);
position = new LatLng(latitude, longitude);
一个问题可能是查找不是在后台线程中完成的，请尝试从我的回答中复制粘贴代码：Google Geocoder service is unavaliable (Coordinates to address)
然后 运行 new GetAddressPositionTask().execute("someAddress") 看看会发生什么。
正在将上下文传递给 AsyncTask：
添加构造函数：
public class GetAddressPositionTask extends
AsyncTask<String, Integer, LatLng> {
private Context context;
public GetAddressPositionTask(Context context) {
this.context = context;
}
// .. rest of the code here
}
用法：
GetAddressPositionTask(context).execute("someAddress")
如果从片段调用，context 是 getApplicationContext() 或 getActivity().getApplicationContext()。
关于空指针：
不是 100% 清楚您从哪里获得空指针，但您应该可以这样做：
// in onPostExecute
i.putParcelable("latlng", result);
并在 MapsActivity
LatLng position = (getIntent() != null) ? getParcelable("latlng") : null;
另一个值得关注的地方是this.mainContxt。只需执行 YourActivity.this 或 getApplicationContext()。如果您在片段中，请执行 Context context = getActivity() 并确保它不为空。
在我的应用程序中，我有一个 activity，您可以在其中根据您在 edittext 中键入的地址在地图中固定位置，或者您可以移动它出现在 onMapReady 函数中的固定位置。
我的 activity 的布局有显示地图的片段，一个按钮 return 关于前一个 activity 中图钉位置的信息和一个编辑文本输入地址并按下按钮，地图上的前一个图钉将被删除，并出现一个包含您输入的位置的新图钉（如果存在）。

这一行：
12386-12386/guide_me_for_all.guide_me_for_all A/libc﹕ Fatal signal 6 (SIGABRT) at 0x000008d2 (code=0), thread 12386 (uide_me_for_all) ,
我不知道括号中的这个东西是什么，但我的包名称是 guide_me_for_all 而不是 uide_me_for_all。 （以防与此有关）
如果有人能帮我看看以上是什么意思，我将不胜感激。
修改以上代码后更新： 从 class 到前一个 activity 到 return 位置的代码（未解决 - 总是得到 NULL 值）：
在class中：
@Override
protected void onPostExecute(LatLng result) {
Log.i("GEOCODE", result.toString());
Intent i = new Intent(this.mainContxt , MapsActivity.class );
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra( "latlng" , result );
this.mainContxt.startActivity(i);
super.onPostExecute(result);
}
在 MapsActivity 的 onCreate 中，我有这个：
if (getIntent() != null) {
Intent intent = getIntent();null){
position_from_address = intent.getStringExtra("latlng");
}
然后在我的 activity 的搜索按钮的 onClickListener 中，我得到这样的位置：
if (position_from_address != null){
String[] latlong = position_from_address.split(",");
double latitude = Double.parseDouble(latlong[0]);
double longitude = Double.parseDouble(latlong[1]);
position = new LatLng(latitude, longitude);
一个问题可能是查找不是在后台线程中完成的，请尝试从我的回答中复制粘贴代码：Google Geocoder service is unavaliable (Coordinates to address)
然后 运行 new GetAddressPositionTask().execute("someAddress") 看看会发生什么。
正在将上下文传递给 AsyncTask：
添加构造函数：
public class GetAddressPositionTask extends
AsyncTask<String, Integer, LatLng> {
private Context context;
public GetAddressPositionTask(Context context) {
this.context = context;
}
// .. rest of the code here
}
用法：
GetAddressPositionTask(context).execute("someAddress")
如果从片段调用，context 是 getApplicationContext() 或 getActivity().getApplicationContext()。
关于空指针：
不是 100% 清楚您从哪里获得空指针，但您应该可以这样做：
// in onPostExecute
i.putParcelable("latlng", result);
并在 MapsActivity
LatLng position = (getIntent() != null) ? getParcelable("latlng") : null;
另一个值得关注的地方是this.mainContxt。只需执行 YourActivity.this 或 getApplicationContext()。如果您在片段中，请执行 Context context = getActivity() 并确保它不为空。
