Question

我有以下文件：supl_zak.xlsx。我对G6的输出是：

10-20 12:55:38.521 30921-30921/tona_kriz.kriziksupl I/System.out: Row: 8 - Column: 7 =

（是的，什么都没有），GUI将消失（崩溃？）但整个应用程序仍在运行。它读取的所有其他单行字符串都不是以空格结尾。

我探索了.xlsx文件并找到了该单元格的字符串：

<t xml:space="preserve">Tv/Jk=0 ------- </t>

如何使其不会崩溃并使用this?

之类的输出

（是的，我使用Gimp使它看起来像这样：P，但透明度失败.PS：文字颜色没关系，我使用了错误的颜色。）

对我来说有什么解决方案吗？我可以录制（bandicam，fraps，..）模拟器和logcat看起来如何？
