@ integer/google_play_services_version的价值是什么？ – justDroid

请检查我的答案。 –

thnx，对不起我睡着了XD –

更新代码。我希望它可以帮助你。它为我工作！

package com.sahaab.muslimzone.activity; 

import com.sahaab.android.muslimzone.test.R; 

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

public class IqamahActivity extends FragmentActivity { 

GoogleMap map; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_iqamah); 
map =((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.iqamah_map)).getMap(); 

    } 
}

更改XML

<?xml version="1.0" encoding="utf-8"?> 
    <fragment xmlns:android="http://schemas.android.com/apk/res/android" 
       android:id="@+id/iqamah_map" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent" 
       android:name="com.google.android.gms.maps.SupportMapFragment" />

@A使用** MapFragment **有什么不对？ –

@SimplePlan先生：我面临同样的问题。然后使用它。实际上，SupportMapFragment属于v4支持库，与默认的MagFragment相反，它是Android中的本地组件。 –

如果有什么错误的想法..让我更多。 –

阿米亚·是正确的，你需要使用FragmentActivity使用片段。

要找出Activity和FragmentActivity之间的区别，this可能会有所帮助！

如果您的目标是API 12及以上版本，则可以使用MapFragment。否则，请使用SupportMapFragment。

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

希望这会有所帮助！
