Android 使用parse.com填充ListView

我正在构建一个应用程序，该应用程序将显示parse.com应用程序中名为“ParseQueryAdapter”的表/类“messages”中“NameMessage”列的值，单击“display”按钮即可显示。单击显示按钮时不会发生任何事情，第二次单击显示按钮时应用程序崩溃。我也在连接logcat。请帮忙。谢谢

屏幕截图不可用，请上传到这里。我昨天看到了相同的问题……是的，佩德罗和我对代码进行了更改，现在我收到了不同的错误。我已经更改了屏幕截图链接，请检查。我不能在这里上传。需要10个信誉点才能向我们展示你的进口产品你不是在进口R。
