Question

android 测试httpClient出错

源代码如下：
package com.example.httptest;

import java.io.BufferedReader;
...

public class HttpActivity extends Activity {

TextView info;
Button button1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
info = (TextView) findViewById(R.id.info);
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet get = new HttpGet("http://www.baidu.com");
String result;
try {
HttpResponse response = httpClient.execute(get);
InputStream inputStream = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(
new InputStreamReader(inputStream));
String line = "";
result = "";
while((line = reader.readLine())!=null){
result = result + line;
}
System.out.println(result);
info.setText(result.toString());
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();}}});
}
}

等等，有好多

Answer 1

1这些log不是你的程序产生的
2你不应该在UI线程中执行网络请求，把httpclient那些放到线程里执行

追问

新开线程，但还是出错
