Java Android-通过文本文件传递Url

我试图通过字段文本传递url以生成HttpPost，但出现以下错误：

Target host must not be null, or set in parameters. scheme=null, host=null, path=android.support.v7.widget.AppCompatEditText%7B1647e90+VFED..CL.+......I.+0%2C0-0%2C0+%237f0d00ad+app%3Aid%2Ffield_url%7D

这是我的密码

-服务

class ThreadInBackgroud extends Thread{
    public void run(){
        try{

            Log.i("LOG", "LocationService.doInBackground()");
            HttpConnection.getSetDataWeb(URLEncoder.encode(Settings_Fragment.url,"UTF-8"),
                    "send-map-coords",
                    mMessageEB);
            stopSelf();

        }catch (Exception e) {
            Log.e("LOG", e.getMessage(),e);
        }

    }
}

-碎片

Button saveButton = (Button) view.findViewById(R.id.btn_save);
    saveButton.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {

            SharedPreferences.Editor editorUrl = getActivity().getSharedPreferences("url_key", MODE_PRIVATE).edit();
            editorUrl.putString("url_key", url_field.getText().toString());
            editorUrl.commit();

        }
    });

    url = url_field.toString();

-HttpConnection

 public static String getSetDataWeb(String url, String method, MessageEB m) throws UnsupportedEncodingException {
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(URLEncoder.encode(url,"UTF-8"));

我希望将url作为变量传递，以便用户可以通过文本字段更改url

url = url_field.toString();

url = url_field.toString();

到

因为需要调用

getText（）

方法才能从输入字段中获取文本，否则调用视图对象上的

toString（）

方法将给出它的

字符串表示形式

到

并公开url，以便您可以在其他服务中访问

public String url;

您不应该对整个URL进行编码，因为这将导致一些类似垃圾的错误

这将失败，因为无法将其解析为正常的HTTP URL

相反，尝试使用

HttpPost HttpPost=新的HttpPost（“URL/…”）
 我不知道使用共享偏好是否是最好的方法嘿。通过这种修改，我能够获得存储在文本字段中的字符串。但我仍然在路径上遇到同样的错误。java.lang.IllegalStateException:目标主机不能为null，也不能在参数中设置。scheme=null，host=null，path=@ClaudioCastro：只需使用
