问题
I'm making an application and ran into a problem.
I made separately app for google maps and it worked perfect, and I made second app in which I have listview, and by clicking on item in listview, another activity starts where google maps with different marks opens.
So I manage to get another activity running after clicking on separate objects in listview, so I modified that objects .xml and .java file on same principle as I did in my google maps app but somehow it doesn't works.
Main_Activity
package com.example.e_idem;
import android.os.Bundle;
import android.app.AlertDialog;
import android.app.ListActivity;
import android.content.DialogInterface;
import android.content.Intent;
import android.view.Gravity;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends ListActivity {
String [] usluga = {
"Frizerski salon",
"Kafić",
"Vodoinstalater",
"Bravar",
"Ljekarna",
"Pekara",
"Autoservis",
"Dućan",
"Knjižnica",
"Papirnica",
"Željezara",
"Smartshop",
"Servis bicikla"
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Odaberite uslugu koju tražite.")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
AlertDialog alert = builder.create();
alert.show();
TextView messageView = (TextView)alert.findViewById(android.R.id.message);
messageView.setGravity(Gravity.CENTER);
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, usluga));
}
public void onListItemClick(ListView parent, View view, int position,long id)
{
Toast.makeText(this, "Odabrali ste uslugu : "+usluga[position], Toast.LENGTH_LONG).show();
switch( position )
{
case 0: Intent activity_frizerski_salon = new Intent(this, FrizerskiSalon.class);
startActivity(activity_frizerski_salon);
break;
case 1: Intent activity_kafic = new Intent(this, Kafic.class);
startActivity(activity_kafic);
break;
case 2: Intent activity_vodoinstalater= new Intent(this, Vodoinstalater.class);
startActivity(activity_vodoinstalater);
break;
}
}
}
Activity I call in Main_Activity for clicking an object in listview
package com.example.e_idem;
import com.google.android.gms.maps.*;
import com.google.android.gms.maps.model.*;
import android.app.Activity;
import android.app.ListActivity;
import android.os.Bundle;
public class FrizerskiSalon extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_frizerski_salon);
// Get a handle to the Map Fragment
GoogleMap map = ((MapFragment) getFragmentManager()
.findFragmentById(R.id.fmap)).getMap();
LatLng vz = new LatLng(46.305746, 16.336606);
map.setMyLocationEnabled(true);
map.moveCamera(CameraUpdateFactory.newLatLngZoom(vz, 13));
map.addMarker(new MarkerOptions()
.title("Varaždin")
.snippet("Barokni grad")
.position(vz));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.flag_red))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(46.300274, 16.330769)));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.flag_red))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(46.306274, 16.300769)));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.flag_red))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(46.306974, 16.303169)));
map.addMarker(new MarkerOptions()
.icon(BitmapDescriptorFactory.fromResource(R.drawable.flag_red))
.anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
.position(new LatLng(46.302874, 16.400710)));
}
}

回答1:
you need 2 meta-data entries in your manifest file:
1) map key
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyCKxxxxxxxxxxxxxxxxxxVfSY_9zxmU"/>
2) google play services version
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
You are missing the second one
