HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {

公共类上载扩展活动实现OnClickListener{
编辑文本笑话;
按钮上传;
AlertDialog AlertDialog=新建AlertDialog.Builder(this.create();

创建时受保护的void(Bundle savedInstanceState){
//TODO自动生成的方法存根
super.onCreate(savedInstanceState);
setContentView(R.layout.upload);
}
公共void onClick(视图v){
//TODO自动生成的方法存根
开关(v.getId()){
案例R.id.bUpload:
上传笑话();
打破
}
}
私有void上传笑话(){
//创建一个新的HttpClient和Post头
HttpClient HttpClient=新的DefaultHttpClient();
HttpPost HttpPost=新的HttpPost(“http://xxxx/telejoke.php");
试一试{
//添加您的数据
List nameValuePairs=新的ArrayList(2);
添加(新的BasicNameValuePair(“用户名”、“测试”);
添加(新的BasicNameValuePair(“笑话”,笑话.getText().toString());
setEntity(新的UrlEncodedFormEntity(nameValuePairs));
//执行HTTP Post请求
HttpResponse response=httpclient.execute(httppost);
}捕获(客户端协议例外e){
alertDialog.setTitle(“客户端协议异常”);
}捕获(IOE异常){
alertDialog.setTitle(“IOException”);
}
}
}
然而,当我尝试在我的android手机上运行它时,它只是因为意外错误而崩溃。感谢您的帮助。移动
AlertDialog-AlertDialog=new-AlertDialog.Builder(this.create()
在UploadChake
方法中修复了此问题。你好,moesef,请发布错误日志,这样,我可以建议更改,Thxy您正在主线程中运行网络操作,我建议您在新线程或AsyncTask中移动网络操作,错误与AlertDialog有关。当我将AlertDialog移动到uploadJoke方法中时,它会删除错误。。。但是我仍然不认为数据被发布到我的PHP脚本中。事实上,AlertDialog是阻止它工作的错误。Thx的帮助@KPBird应该首先查看错误日志。
