我在运行应用程序时遇到未知问题。我尝试了很多次，以找到解决方案，但没有任何链接帮助我。 我想要的是显示谷歌地图，而用户点击名为get get button的正按钮 帮助！由于未知错误导致地图未打开
Set_Coordinate.java
public class Set_Coordinates extends FragmentActivity{
private static final int GPS_ERRORDIALOG_REQUEST = 9001;
GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(servicesOK()){
Toast.makeText(this, "Ready to map!", Toast.LENGTH_SHORT).show();
setContentView(R.layout.activity_map);
}
else{
setContentView(R.layout.set_coordinates);
}
}
public boolean servicesOK(){
int isAvaliable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if (isAvaliable == ConnectionResult.SUCCESS){
return true;
}
else if (GooglePlayServicesUtil.isUserRecoverableError(isAvaliable)){
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvaliable, this, GPS_ERRORDIALOG_REQUEST);
dialog.show();
}
else{
Toast.makeText(this, "Can't connect to Google Play Services", Toast.LENGTH_SHORT).show();
}
return false;
}
}
这是activity_map.xml

喔我知道了！但是现在我该怎么办？ –
重命名文件或类 – FrancescoC
我将我的类从Set_Coordinates重命名为SetCoordinates，但面临相同的错误 –
