本文介绍了一个Android应用中通过点击事件触发HTTP GET请求的方法。具体实现包括设置点击监听器、构建HTTP请求、使用HttpClient发送请求并处理服务器返回的数据。

this.captureView.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub

    HttpGet httpGet = new HttpGet("http://172.31.71.151:8080/HttpAndroid/servlet/testServlet?name=黄聊");

   //get方法，网址为Tomcat中的的 http://172.31.71.151:8080/HttpAndroid/servlet/testServlet servlet代码，web.xml数据
    HttpClient httpClient = new DefaultHttpClient();


    try {
     HttpResponse httpResponse = httpClient.execute(httpGet); //服务器返回的响应
     HttpEntity httpEntity = httpResponse.getEntity(); //服务器端返回的数据就包含在HttpEntity中
     InputStream inputStream = httpEntity.getContent();
     BufferedReader bufferReader = new BufferedReader(new InputStreamReader(inputStream));
     String result ="";
     String line = "";
     while((line = bufferReader.readLine())!=null){
      result = result + line;
     }
     System.out.println(result);
     Toast.makeText(getApplicationContext(), result, 0).show();

    } catch (ClientProtocolException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    } catch (IOException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }

}
});
