onItemSelected Not called for the first time for Android and The cursor does not disappear

[qinAI]

The Android input box cursor does not disappear when switching from a normal keyboard to a custom keyboard. onItemSelected needs to be clicked twice. The first time the cursor disappears. The second time will return onItemSelected.
从普通键盘切换到自定义键盘时，Android输入框光标不会消失。 需要单击onItemSelected两次才会回掉。 第一次光标消失。 第二次将返回onItemSelected的值。
iOS没有上述问题
