Question

我是Android新手，我遇到了这个问题我正在尝试制作一个程序，从最好的提供商处获取我的位置。之后它会从链接中获取图像，我不知道代码中的错误位置。

这些是我得到的错误

第102行此行有多个标记 - 语法错误，插入“}”以完成Statement - 语法错误，插入“else语句”完成 IfStatement

第142行令牌上的语法错误，删除这些令牌

第159行：此行有多个标记 - 令牌“setText”上的语法错误，=此后的预期令牌

第162行

：令牌“}”上的语法错误，删除此令牌

提前谢谢

这是清单文件：

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.paad.whereami"> <application android:icon="@drawable/icon"> <activity android:name=".WhereAmI" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> android:name="android.permission.INTERNET <uses-permission android:name="android.permission.INTERNET"></uses-permission> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission> </manifest>

main.xml中：

不看代码，我的第一个猜测是你试图在模拟器中运行它并没有通过ddms或telnet“geo fix”设置位置？

更新看起来像是复制了粘贴的

private Bitmap DownloadImage(String URL)

和

private InputStream OpenHttpConnection(String urlString)

在错误的位置。你的花括号错了。目前，您在函数内定义了一个函数。

Android位置搜索错误
