推荐答案

您编辑文本

EditText your_edit_text = (EditText) findViewById(R.id.your_id);

获取从编辑文本的用户数据作为休耕。

Get user data from edit text as fallows ..

String edit_text_data = your_edit_text.getText().toString();

现在，当你需要把这些数据的URL。使用此类似。

Now when you need to put that data on url .. use this like ..

String your_url = "http://www.google.com=" + edit_text_data;

更新::

jsonobject = JSONfunctions .getJSONfromURL("http://10.0.2.2:8080/jsondatad/" + edit_text_data);

更新:::
