and I also add the permission into the Manifest.xml
我还将权限添加到 Manifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xenos.study.httpclienttest"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10" />
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".HttpClient"
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>
The whole code is here :
整个代码在这里：
public class HttpClientTest extends Activity {
private HttpClient httpClient ;
private HttpGet httpGet ;
private HttpResponse httpResponse ;
private HttpEntity httpEntity ;
private BufferedReader br ;
private Button link ;
private EditText show ;
private String path = "http://74.125.71.104";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
link = (Button) findViewById(R.id.link);
show = (EditText) findViewById(R.id.show);
httpClient = new DefaultHttpClient () ;
httpGet = new HttpGet(path);
link.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
try {
httpResponse = httpClient.execute(httpGet);
httpEntity = httpResponse.getEntity();
br = new BufferedReader(new InputStreamReader(httpEntity.getContent()));
String str = null ;
while ((str = br.readLine())!=null) {
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
}
It makes me gloomy , thanks for your help.
这让我很沮丧，谢谢你的帮助。
