我试图隐藏软键盘,使其在 EditText 接收焦点或触摸事件时不显示。我希望 EditText 是可编辑的 - EditText 中会有文本,因此我希望 EditText 响应触摸事件,以便定位光标,但我将有专用的编辑按钮,而不是使用软键盘。我无法让它工作 - 软键盘似乎会在 focuschange 和触摸事件上弹出。
我已将代码简化为以下内容:
AndroidMainifest.xml:

if (adView != null)
adView.Resume();
}
private void FocusChange(object sender, View.FocusChangeEventArgs e)
{
InputMethodManager im = (InputMethodManager)GetSystemService(Context.InputMethodService);
im.HideSoftInputFromWindow(Window.DecorView.WindowToken, Android.Views.InputMethods.HideSoftInputFlags.None);

im.HideSoftInputFromWindow(editText.WindowToken, Android.Views.InputMethods.HideSoftInputFlags.None);
(sender as EditText).OnTouchEvent(e.Event);
}
}
}
我尝试过许多 stackoverflow 答案的变体来隐藏键盘,但没有任何效果。任何帮助将不胜感激。
最佳答案
我最终得到了一个棘手的解决方案,它有效,但我不喜欢它。
我有一个带有 EditText
和 Button
的简单布局。当您按下按钮时,我会在光标所在的 EditText
中添加一个“*”。您可以用手指操纵光标,并且软键盘永远不会打开,因为当 EditText 获得焦点时我会隐藏键盘。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText android:id="@+id/myEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Text Here"/>
<Button
android:id="@+id/myButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Click Me!" />
</LinearLayout>
以及Activity
中的代码:
public class MainActivity : Activity, View.IOnTouchListener
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.Main);
EditText edt = FindViewById<EditText>(Resource.Id.myEditText);
edt.SetOnTouchListener(this);
Button button = FindViewById<Button>(Resource.Id.myButton);
button.Click += delegate { edt.Text = edt.Text.Insert(edt.SelectionStart, "*"); };
}
public bool OnTouch(View v, MotionEvent e)
{
// Pass the event to the edit text to have the blinking cursor.
v.OnTouchEvent(e);
// Hide the input.
var imm = ((InputMethodManager)v.Context.GetSystemService(Context.InputMethodService));
imm?.HideSoftInputFromWindow(v.WindowToken, HideSoftInputFlags.None);
return true;
}
}
最终结果
关于c# - 隐藏用于 editText 焦点/触摸的软键盘,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/38956548/
