当我使用片段时，我的应用程序崩溃了，它显然与GoogleMap其中一个片段有关。

我已经将地图片段从更改为MapFragment，SupportMapFragment但没有帮助。

这是所有片段所在的主页（FragmentActivity）：

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.view.View;

public class Fragments extends FragmentActivity {

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

        MainActivity fragment = new MainActivity();
        FragmentTransaction transaction = getSupportFragmentManager()
                .beginTransaction();
        transaction.add(R.id.fragment_place, fragment);
        transaction.commit();
    }

    public void onSelectFragment(View view) {

        Fragment newFragment;

        if (view == findViewById(R.id.add)) {
            newFragment = new Add();
        } else if (view == findViewById(R.id.map)) {
            newFragment = new MainActivity();
        } else {
            newFragment = new MainActivity();
        }

        FragmentTransaction transaction = getSupportFragmentManager()
                .beginTransaction();
        transaction.replace(R.id.fragment_place, newFragment);
        transaction.addToBackStack(null);
        transaction.commit();
    }

}

并且片段有点大，所以我将它粘贴到了 pastebin 上：

您可以查看我写的关于如何在您的应用程序中集成 Google Map API V2 的这篇博文，它可能会为您提供解决问题的方法：

您需要做的是在您的项目中包含一个 Google Play 服务库。谷歌在这里有很好的说明：

请访问code.google.com并获取您的 ApiKey。

在那里创建一个项目->转到服务->激活 Google Maps Android API v2。然后为您的应用程序创建密钥。

将以下权限添加到您的清单。

 <uses-permission android:name="com.anchit.locationapi.maps.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

利用

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

还可以在您的应用程序标签内添加

<permission
        android:name="com.anchit.locationapi.maps.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

请在您的代码中使用以下内容：

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

我相信你必须使用 SupportMapFragment：http: //developer.android.com/reference/com/google/android/gms/maps/SupportMapFragment.html

这是一个很好的教程： http ://www.truiton.com/2013/05/android-supportmapfragment-example/

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    return inflater.inflate(R.layout.activity_main, container, false);
}

使用它而不是 oncreate()
