我有一段代碼,在我的活動(我開始這個來自模擬器)加載文件 - 拒絕連接
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView txt=(TextView)this.findViewById(R.id.lbl);
try {
URL url = new URL("http://localhost/test.json");
URLConnection urlconnection = url.openConnection();
long l = urlconnection.getContentLength();
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String line;
StringBuffer buffer=new StringBuffer();
while ((line = in.readLine()) != null)
{
buffer.append(line);
}
in.close();
System.out.println("bufer="+buffer.toString());
txt.setText(buffer.toString());
} catch (Exception exc) {
exc.printStackTrace();
}
}
和我的清單看起來像
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="test_android.test"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".test_android"
android:label="@string/app_name">

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>
我有WAMP服務器我的萬維網目錄test.json,但我總是得到錯誤CONNECTION REFUSED。哪裏不對 ?
