Google Maps V2 - 地图未加载 [英] Google Maps V2 - Map is not loading

问题描述

就个人而言，我是一个问题，因为有一段时间我无法解决，我尝试了几种方式，没有什么....然后我做一个APP位置很简单，但不加载，只是在空白屏幕（笛卡尔平面）。以下是源代码。谁可以帮助我，我是Android应用程序的新手。



AndroidManifest.xml

Personally, I'm a problem, since a while I can not solve, I tried several ways and nothing .... then I'm doing an APP location pretty simple, but does not load, is only in Blank Screen (Cartesian plane). Below is the source code. Who can help me, I'm new to Android application.

AndroidManifest.xml

package nl.codestone.cookbook.maptest;

import android.os.Bundle;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;

public class MapTest extends MapActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        MapView mapview = (MapView) findViewById(R.id.mapview);
        mapview.setBuiltInZoomControls(true); 
    
    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }
}

main.xml

main.xml

<?xml version="1.0" encoding="utf-8"?>

<com.google.android.maps.MapView  

    xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/mapview"

    android:layout_width="fill_parent" 

    android:layout_height="fill_parent" 

    android:apiKey="AIzaSyBLRbJiQXyenW5t5P0U4tjxfWQhpDpfbcA"

    android:clickable="true"

    />

MapTest.java

package nl.codestone.cookbook.maptest;

import android.os.Bundle;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;

public class MapTest extends MapActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        MapView mapview = (MapView) findViewById(R.id.mapview);
        mapview.setBuiltInZoomControls(true); 
    
    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }
}
