Java JSON对象到JSON数组到Arraylist到Arraydapter
我想问一下如何显示我的数组列表，我从我的webhost数据库获取数据并将其传递给JSON对象，然后我使用JSON数组将我的对象作为数组，然后我将其传递给ArrayList以显示我获得的所有数据，如果我打印ArrayList的输出，我得到的结果如下Java JSON对象到JSON数组到Arraylist到Arraydapter,java,android,arrays,json,arraylist,Java,Android,Arrays,Json,Arraylist,我想问一下如何显示我的数组列表，我从我的webhost数据库获取数据并将其传递给JSON对象，然后我使用JSON数组将我的对象作为数组，然后我将其传递给ArrayList以显示我获得的所有数据，如果我打印ArrayList的输出，我得到的结果如下 I/System.out: {"checkdate":"Oct 31, 2016","checkno":"123","datepaid":"Oct 31, 2016","clientname":"naruto","bank":"bdo","amount

如果（arr！=null）{
因为（inti=0；我非常感谢你：）你帮了我很多：）现在，我只需要将值分配给textView？以使其正确显示数据（不客气：）要包含所有字段，您必须创建一个自定义适配器和模型对象。再次感谢：）我几乎用了3天的时间来显示这些数据哈哈哈
