单击外部 Edittext 后如何在 Xamarin Android 中隐藏键盘

How to Hide keyboard in Xamarin Android after clicking outside Edittext

我正在研究 Xamarin(Android)。现在我想在 Edit Text 外部单击后隐藏键盘。

提前致谢。

public class MainActivity : Activity
{


    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

        // Set our view from the "main" layout resource
        RequestWindowFeature(WindowFeatures.NoTitle);


        SetContentView(Resource.Layout.Main);

        EditText Etusername= FindViewById<EditText>(Resource.Id.EtUname);
        Etusername.SetHintTextColor(Color.Gray);

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

使用此代码隐藏 Keyboard

public override bool OnTouchEvent(MotionEvent e)
    {
         InputMethodManager imm = (InputMethodManager)GetSystemService(Context.InputMethodService);
         imm.HideSoftInputFromWindow(Etusername.WindowToken, 0);
         return base.OnTouchEvent(e);
    }

并确保您必须添加此库:

using Android.Views.InputMethods;
