我的自定义列表视图无法正常工作。它工作正常，直到我没有滚动到最后，但是当我滚动结束其 onclick 功能停止工作时，我正在使用自定义列表扩展基本适配器..
我已将单击侦听器设置为 togle，为此，我已在自定义行中将可聚焦设置为 false。
但我注意到的一件事是，每当我的列表停止点击时，日志中就会生成以下错误。
05-18 17:54:02.674: W/KeyCharacterMap(4343): Can't open keycharmap file
05-18 17:54:02.674: W/KeyCharacterMap(4343): Error loading keycharmap file '/system/usr/keychars/cy8c-touchscreen.kcm.bin'. hw.keyboards.65537.devname='cy8c-touchscreen'
