Google Maps API v2无法显示地图

时间：2013-06-22 15:44:59

标签： android google-maps

我是Stackoverflow的新手。我在新版Google Maps API v2上替换地图时遇到问题。 我完成了本页的所有步骤https://developers.google.com/maps/documentation/android/start?hl=pl和一些教程，我无法显示地图。当我运行我的应用程序时，在模拟器上显示只有放大控件和休息屏幕是白色的我无法在我的真实设备上打开它（HTC Wildfire S- android 2.3.5）。我也将google_play_service_lib添加到了我的项目中。我在很多页面和很多教程中寻找我的问题的答案，但我没有找到它！请帮帮我！

这是我的清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

有MainActivity的代码：

package com.adrianspora.googlemaptest;

import com.google.android.gms.maps.MapFragment;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

这是主要布局的代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >


<fragment 
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

</LinearLayout>

LogCat中显示了一系列日志：

5 个答案:

答案 0 :(得分：4)

你应该使用Support Fragment，因为你的min sdk是8。

https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/SupportMapFragment 

<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"  
android:layout_width="match_parent"
android:layout_height="match_parent"/>

您的活动必须延长FragmentActivity并使用以下内容初始化GoogleMap对象。

SupportMapFragment fm = (SupportMapFragment)  getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap();

确保您已添加支持库

同时确保导入以下内容

import android.support.v4.app.FragmentActivity;  
import com.google.android.gms.maps.SupportMapFragment;

检查您是否在服务标签下的google api控制台中为启用了Android地图。

检查您是否已按照文档中提到的所有步骤进行操作

https://developers.google.com/maps/documentation/android/start

您也可以查看我回答的类似问题。

您应该在真实设备上进行测试。

答案 1 :(得分：0)

您应该使用SupportMapFragment，因为您的API级别是2.3.5

使用以下代码替换XML中的片段：

    <fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.SupportMapFragment" />

并且还在Java文件中导入此类，而不是MapFragment。

此外，作为一般建议，如果您想支持蜂窝前蜂窝设备并使用碎片等，则应使用Support library。

答案 2 :(得分：0)

您使用的是哪种API密钥？您应该在编程时始终使用开发键，并且您的应用需要在Google API控制台中注册。

您必须在偏好设置/ Android 中添加google-play-services-library，而不是偏好设置/ Java构建路径。

答案 3 :(得分：0)

You have to use FragmentActivity

public class PlacesMapActivity extends android.support.v4.app.FragmentActivity
    implements OnClickListener, LocationListener {

ImageButton btn_home;
private GoogleMap mMap;


protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);

    SupportMapFragment fragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mMap = fragment.getMap();
    mMap.setMyLocationEnabled(true);

    // mMap = ((SupportMapFragment) getSupportFragmentManager()
    // .findFragmentById(R.id.map)).getMap();

    MarkerOptions markerOptions = new MarkerOptions();
    markerOptions.title("First Location");
    markerOptions.snippet("This Is Test Location");

    LatLng latlng = new LatLng(23.0333, 72.6167);

    markerOptions.position(latlng);
    // markerOptions.title("Ahmedabad Cordinat Found here");

    // Marker m = mMap.addMarker(markerOptions);

    mMap.setInfoWindowAdapter(new InfoWindowAdapter() {

        @Override
        public View getInfoWindow(Marker arg0) {

            return null;
        }

        @Override
        public View getInfoContents(Marker marker) {

            View myContentView = getLayoutInflater().inflate(
                    R.layout.custommarker, null);
            TextView tvTitle = ((TextView) myContentView
                    .findViewById(R.id.title));
            tvTitle.setText(marker.getTitle());
            TextView tvSnippet = ((TextView) myContentView
                    .findViewById(R.id.snippet));
            tvSnippet.setText(marker.getSnippet());
            return myContentView;

        }
    });

    mMap.addMarker(new MarkerOptions()
            .position(latlng)
            .title("This is Sabarmati Ashram")
            .snippet("Ahmedabad")
              .icon(BitmapDescriptorFactory                     .defaultMarker(BitmapDescriptorFactory.HUE_RED)));

    mMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {

        @Override
        public void onInfoWindowClick(Marker arg0) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(getBaseContext(),
                    DetailsOfPlacesActivity.class);
            startActivity(intent);
        }
    });

    btn_home = (ImageButton) findViewById(R.id.activity_map_ibtn_home);
    btn_home.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            finish();
        }
    });
}

答案 4 :(得分：0)

我遇到了同样的错误并尝试了6个教程，并阅读了谷歌的所有文档。最后，我让它运行并显示地图。这就是它对我有用的方式。

1.从你的eclipse和你的PC上删除库google-play-services和android support-v4。 2.从de sdk-manager再次下载。 3.按照说明[此处]（https://developers.google.com/maps/documentation/android/intro#sample_code）转到示例代码并按照说明进行操作。请特别检查此现有Android代码到工作区，不要将库作为项目导入，它们将无法正常工作。 4.更改所有MapFragment for SupportMapFragment，不要忘记将你的Actvity扩展到FragmentActivity（这是我的失败）。 5.Disable（如果已启用）自动构建项目中的选项。 6.清理项目。 5.自动启用构建选项。

它应该有用。
