Question

我刚刚按照本教程（https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2）来展示Google地图。但是，当我尝试在手机（ZTE V875）中初始化应用程序时，我收到错误，或者更好地说出错误列表。有谁知道为什么？提前谢谢。

在我的MainActivity.class中，我有以下代码：

package com.example.tutorialgooglemaps;


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

public class MainActivity extends FragmentActivity {

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

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

}

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?>
<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" />

Answer 1

我评论了一个类似的问题。也许我的答案也可以解决你的问题！？

google map - runtimeexception - error inflating class fragment

Answer 2

如果有人遇到同样的问题，问题出在activity_main.xml，其中需要LinearLayout或RelativeLayout。谢谢大家

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >


<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" />
</LinearLayout>
