加载地图时应用程序停止

嗨我想要我的应用程序内的地图...... 我复制了三个教程，我为每个项目更改了密钥，结果是＆＃34;应用已停止＆＃34; 我使用Frangment或SupportFrangment .... 为什么我的三星S4没有执行应用程序看地图？

现在我解释一下我的应用程序在哪里复制并更改tutorial 前提： 我加载了google-play-service两次： 1-文件 - ＆gt;导入 - ＆gt;现有项目进入工作区 - ＆gt; google-play-services并包含在每个项目中

2 - 在项目属性中添加库google-play-services。

哪里错了？ 这是manifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.com.vogella.android.locationapi.maps"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk

        android:targetSdkVersion="19" />

    <application

        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.com.vogella.android.locationapi.maps.ShowMapActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="KeyVALUE API" />
    </application>

</manifest>

这是一个frangment.xml：

<RelativeLayout 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"
    tools:context=".ShowMapActivity" >

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

</RelativeLayout>

这是一个ShowMapActivity.java：

    package com.example.com.vogella.android.locationapi.maps;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;

import com.google.android.gms.maps.CameraUpdateFactory;

import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;

public class ShowMapActivity extends Activity {
  static final LatLng HAMBURG = new LatLng(53.558, 9.927);
  static final LatLng KIEL = new LatLng(53.551, 9.993);
  private GoogleMap map;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_show_map);
    map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
        .getMap();
    Marker hamburg = map.addMarker(new MarkerOptions().position(HAMBURG)
        .title("Hamburg"));
    Marker kiel = map.addMarker(new MarkerOptions()
        .position(KIEL)
        .title("Kiel")
        .snippet("Kiel is cool")
        .icon(BitmapDescriptorFactory
            .fromResource(R.drawable.ic_launcher)));

    // Move the camera instantly to hamburg with a zoom of 15.
    map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

    // Zoom in, animating the camera.
    map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
  }

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.show_map, menu);
    return true;
  }

}

2 个答案:

答案 0 :(得分：1)

在您的AndroidManifest中，您说过您将提供名为MainActivity的课程，但您已将其重命名为ShowMapActivity，这意味着系统无法找到该活动它应该使用

答案 1 :(得分：0)

您需要使用较新的地图SupportMapFragment而不是MapFragment，并使用name标识符来查找SupportMapFragment的类。

<强>样品： 

<RelativeLayout 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"
tools:context=".ShowMapActivity" >

<fragment
    android:id="@+id/map"
    android:name="com.androidmapsextensions.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

</RelativeLayout>

此外，您需要将地图的转换更改为SupportMapFragment。

SupportMapFragment map;

map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map))
    .getMap();
