Question

尝试了很多次以避免这种错误总线仍然无法找到答案。这是我的第一个使用谷歌API的应用程序。我想在屏幕上显示地图。我得到了＃34;膨胀类片段＆＃34;错误并尝试了我发现的这么多解决方案，但我仍然得到同样的错误。请帮忙！

MainActivity.java

package com.example.testmap;

import com.google.android.gms.maps.GoogleMap;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.Toast;
import com.google.android.gms.maps.MapFragment; 

public class MainActivity extends Activity {

    private GoogleMap googleMap;


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


        if (googleMap == null) {
            googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                    R.id.map)).getMap();

            // check if map is created successfully or not
            if (googleMap == null) {
                Toast.makeText(getApplicationContext(),
                        "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                        .show();
            }
        }


    }

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

}

activity_main.xml中

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

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

Answer 1

使用以下

替换您的片段代码

<fragment 
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.SupportMapFragment"/>

据我所知，MapFragment适用于较旧的API版本。

Answer 2

您没有write外部存储权限，因此请添加

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

在您的权限

中

扩展类片段时出错。
