单击按钮后如何在JSON中获取ID并想在post方法中再次发送该ID

Question

实际上我正在解析json id，content，title，count。但是我不想显示id，但是在单击按钮后它必须获取id值，并且我必须将该id发送到服务器端。

这是我的json解析值：

{"post":[{"id":170,"title":"Exams","content":"pass","count":3},{"id":169,"title":"Exams","content":"pass","count":3},  From here i want to get the id after click the pray button and want to send that id in post method also.

Activity.java

    private static final int ACTIVITY_CREATE=0;

        setContentView(R.layout.activity_list_item);  
         //mDbHelper = new ProjectsDbAdapter(this);
            //mDbHelper.open();
            //fillData();
            //registerForContextMenu(getListView());
         praycount = (Button) findViewById(R.id.pray);

         praycount.setOnClickListener(new View.OnClickListener() {

其实我想我想得到一个我已经提到过的json的ID，在单击按钮选择ID之后，我想在另一个json url中再次发送作为post方法。

为此，您可以使用javascript读取所选特定属性的ID，并使用它来显示所需的详细信息。
