Android位置搜索錯誤

Question

我是新來的Android，我有這個問題我試圖做一個程序，將從最好的供應商得到我的位置。之後，它會從鏈接中獲取圖像，並且我不知道代碼中的錯誤位置。

這些都是錯誤的，我得到

在線路102個 在該行 多個標記 - 語法錯誤，插入「}」來完成陳述 - 語法錯誤，插入「else語句」，完成 IfStatement

在線路142上記號 語法錯誤，刪除這些令牌

在行159： 多個標記在該行 - S yntax令牌「的setText」的錯誤，=預計 令牌

在線路162後： 語法令牌「}」的錯誤，刪除此令牌

預先感謝您

這是清單文件：

<?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>

的main.xml：

'

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 
    <TextView 
    android:id="@+id/myLocationText" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"/> 
    <ImageView 
    android:id="@+id/img" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center" 
    /> 
</LinearLayout>

不看代碼，我的第一個猜測是，你嘗試在運行它模擬器並沒有通過ddms或telnet「geo fix」設置位置？

更新看起來你複製粘貼

private Bitmap DownloadImage(String URL) 

和

private InputStream OpenHttpConnection(String urlString) 

在錯誤的位置。你的花括號是錯的。目前你在函數中定義一個函數。
