android - 无法扩充 android.view.inflateException.Binary xml 文件行 #2

Question

friend 们请帮帮我.. 我有一个显示谷歌地图的简单应用程序..当我运行该应用程序时出现错误“不幸的是该应用程序已停止”

log cat 中的错误是:Failed to inflateandroid.view.inflateException.Binary xml 文件第 2 行:在 android view.LayoutInflater.createViewFromTag(LayoutInflater.java.713) 中膨胀类 fragment 时出错

我已经尝试了 stackoverflow 和许多其他网站提供的许多答案。但在所有这些情况下，我都会遇到同样的错误。

我的代码:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mapview"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

主 Activity .java

package info.androidhive.googlemapsv2;

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

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

public class MainActivity extends FragmentActivity {

    private GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        map = ((MapFragment) getFragmentManager()
                .findFragmentById(R.id.mapview)).getMap();
    }
}

Answer 1

像这样将您的 map fragment 放在 RelativeLayout 或 LinearLayout 中；

<?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
        android:id="@+id/mapview"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

 </RelativeLayout>

然后改变

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

有了这个;

setUpMap();

setUpMap() 函数定义将是；

private void setUpMap(){
    if (map != null) {
        return;
    }
    map=((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapview)).getMap();
    if (map == null) {
        return;
    }
}

哦，你也很想念

<meta-data 
   android:name="com.google.android.gms.version" 
   android:value="@integer/google_play_services_version" />

在您的 list 文件中。检查this link
