在MvxFragment中关闭/隐藏Android软键盘

Fet*_*mos 7 android android-softkeyboard mvvmcross xamarin

我用xamarin + mvvmcross创建了android应用程序.我的MvxFragment中有一个MvxAutoCompleteTextView.在MvxAutoCompleteTextView中写入并单击其他控件后,我想隐藏虚拟键盘.我用这个代码

public class MyFragment : MvxFragment 
{
    public override View OnCreateView(LayoutInflater inflater, ViewGroup container,  Bundle savedInstanceState)
    {

        base.OnCreateView(inflater, container, savedInstanceState);
        var view = this.BindingInflate(Resource.Layout.frMy, null);
        var autoComplete = view.FindViewById<MvxAutoCompleteTextView>(Resource.Id.acMy);
        InputMethodManager inputManager = (InputMethodManager)inflater.Context.GetSystemService(Context.InputMethodService);
        inputManager.HideSoftInputFromWindow(autoComplete.WindowToken, HideSoftInputFlags.None);
        return view;
    }
}

但这不行.如何隐藏键盘?

您可以隐藏软键盘,将焦点放在不是"键盘启动器"控件的位置,例如,自动完成控件的父容器.

parentContainer = FindViewById<LinearLayout>(Resource.Id.parentContainer);
parentContainer.RequestFocus();

假设您的父容器是LinearLayout,您应该允许它使用这两个属性获得焦点:

<LinearLayout
    android:id="@+id/parentContainer"
    android:focusable="true"
    android:focusableInTouchMode="true">

我从这里得到了答案:https://stackoverflow.com/a/28939113/4664754

这是C#版本(经过测试和运行):

public override bool DispatchTouchEvent(MotionEvent ev)
{
    if (ev.Action == MotionEventActions.Down)
    {
        View v = CurrentFocus;
        if (v.GetType() == typeof(EditText))
        {
            Rect outRect = new Rect();
            v.GetGlobalVisibleRect(outRect);
            if (!outRect.Contains((int)ev.RawX, (int)ev.RawY))
            {
                v.ClearFocus();
                InputMethodManager imm = (InputMethodManager)this.GetSystemService(Context.InputMethodService);
                imm.HideSoftInputFromWindow(v.WindowToken, 0);
            }
        }
    }
    return base.DispatchTouchEvent(ev);
}

如果您单击任何不是EditText的内容,这段代码将隐藏软键盘.您只需将其粘贴到您的活动类中(例如您的loginActivity)

尝试这个:

InputMethodManager imm = (InputMethodManager)GetSystemService(Context.InputMethodService);
imm.HideSoftInputFromWindow(autoComplete.WindowToken, 0);

0中的值HideSoftInputFromWindow是 const Android.Views.InputMethods.HideSoftInputFlags.None,因此您可以使用等效语法:

InputMethodManager imm = (InputMethodManager)GetSystemService(Context.InputMethodService);
imm.HideSoftInputFromWindow(autoComplete.WindowToken, Android.Views.InputMethods.HideSoftInputFlags.None);
