解析android中的数据

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

使用网址

如何在这里添加数据请帮我解决任何我刚接触android和java的例子

Answer 1

首先在android Activity

中优先使用EditText

喜欢这个::

EditText yourEditTextName=(EditText)findViewById(R.id.nameofedittext);

然后从EditText

获取文本

String your_url =  "www.google.com/q=" + yourEditTextName.getText().toString();

由于

Answer 2

您的编辑文字

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

将编辑文本中的用户数据视为休闲..

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

现在当你需要将这些数据放在url上时......使用它就像..

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);
