listViewに問題があります。各行に2つのボタンと1つのtextViewを含むlistviewがあります。

オブジェクトを含むarrayListがあります。

tv.setText(obj.getName());行内に表示するにはどうすればよいですか? objの名前ではなくnull値が表示されます!

どうすればこれを修正できますか?

==================================== updating ========================================

in Activity (X) when the user press Sendbutton it'll add the object to :

    Send.setOnClickListener(new View.OnClickListener() {

                public void onClick(View v) {


    ......                              All_Static.MyCaseList.add(case1);
    .....                               


                                }
                            });
