我有一个应该有谷歌地图的布局。但是，当我尝试包含地图时，应用程序崩溃了。没有地图，它工作正常。

这是我的布局

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

        android:text="@string/cinema_filmhall_facility"

<强>问题： 

com.google.android.gms.maps.MapFragment cannot be cast to android.support.v4.app.Fragment

当您尝试使用{MapFragment时，您无法将Fragment投射到原始机器人的ClassCastException，这将导致MapFragment转而使用android:id="@+id/map"投射GoogleMap map = ((MapFragment) getFragmentManager() .findFragmentById(R.id.map)).getMap(); 1}} 

MapFragment

编辑：

<fragment android:id="@+id/map" android:name="com.google.android.gms.maps.SupportMapFragment" android:layout_width="wrap_content" android:layout_height="wrap_content" /> GoogleMap map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); 是旧版本的地图我建议将SupportMapFragment用于更新版本。

尝试将以下权限添加到Manifest.xml文件中。

<permission
        android:name="com.fortuna.cinemalk.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

之前

<uses-sdk
        android:minSdkVersion=".."
        android:targetSdkVersion=".." />

希望这可以帮到你！
