关闭软键盘
View view = getWindow().peekDecorView();
if (view != null) {
InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}```
##打开软键盘
if (view != null) {
InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.showSoftInput(view, 0);
}```
view必须是VISIBLE的EditText，如果不是VISIBLE的，需要先将其设置为VISIBLE。

检查软键盘是否显示
