Android Google Map - 膨胀类片段时出错

Question

我想在我的Activity 上显示GoogleMap。我已经完成了所有必要的步骤，包括密钥生成、链接google-play-services_lib、添加android-support-v4.jar。但是由于Fragment，我面临一个错误。我尝试了很多解决方案，花了很多时间但无法解决这个问题。请帮我。

MapActivity.java

package com.example.classified_android_app;

import android.os.Bundle;   
import android.support.v4.app.FragmentActivity;

public class MapActivity extends FragmentActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);
    }
}

ma​​p.xml

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

    <fragment
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment"
        map:cameraTargetLat="17.660324"
        map:cameraTargetLng="75.906601"
        map:cameraZoom="15" >
    </fragment>

</RelativeLayout>

Answer 1

主要问题是你的android:minSdkVersion="16"

原始文档所说的是

如果您的 android:minSdkVersion > 12 则应使用 MapFragment 扩展 Activity

还有

如果你的android:minSdkVersion < 12 那么你应该使用SupportMapFragment 扩展FragmentActivity

Answer 2

尝试替换

<fragment
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment"
        map:cameraTargetLat="17.660324"
        map:cameraTargetLng="75.906601"
        map:cameraZoom="15" >
    </fragment>

与

<fragment
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
         android:name="com.google.android.gms.maps.SupportMapFragment"
        map:cameraTargetLat="17.660324"
        map:cameraTargetLng="75.906601"
        map:cameraZoom="15" >
    </fragment>

见android官网How to add static fragment from XML提供的这个链接

Answer 3

尝试将此添加到您的 onCreate() 中。

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

并替换它。

<fragment
        xmlns:map="http://schemas.android.com/apk/res-auto"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment"
        map:cameraTargetLat="17.660324"
        map:cameraTargetLng="75.906601"
        map:cameraZoom="15" >
    </fragment>

与

<fragment
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />
        map:cameraTargetLat="17.660324"
        map:cameraTargetLng="75.906601"
        map:cameraZoom="15" >
    </fragment>
