保存按钮启用禁用状态并在创建时获取最后一个状态

Question

我是android的新手，我正在尝试开发一些应用程序。但是过去两周我一直坚持使用这段代码。简而言之，我在布局中有两个按钮。这些按钮是添加和删除按钮。如果我单击添加按钮，将禁用添加并启用删除。或者如果我点击删除，删除将被禁用添加将被启用。我想保存这两个按钮的状态（单击哪个按钮）并在创建时获得最后一次单击状态。但问题是它不起作用。当我打开应用程序时，两个按钮都显示禁用状态。或者也不保存。从不工作。

bool edit(int cmdchar, bool startln, long count)
{
  if (curbuf->terminal) {
    if (ex_normal_busy) {
      // Do not enter terminal mode from ex_normal(), which would cause havoc
      // (such as terminal-mode recursiveness). Instead set a flag to force-set
      // the value of `restart_edit` before `ex_normal` returns.
      restart_edit = 'i';
      force_restart_edit = true;
    } else {
      terminal_enter();
    }
    return false;
  }
  ...
