我的布局中有一个EditText和一个Button。
在编辑字段中写入并单击按钮后,我想在触摸键盘外部时隐藏虚拟键盘。我假设这是一段简单的代码,但我在哪里可以找到它的示例?

我正在使用以下Kotlin Activity扩展:
/**
* Hides soft keyboard if is open.
*/
fun Activity.hideKeyboard() {
currentFocus?.windowToken?.let {
(getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager?)
?.hideSoftInputFromWindow(it, InputMethodManager.HIDE_NOT_ALWAYS)
}
}
/**
* Shows soft keyboard and request focus to given view.
*/
fun Activity.showKeyboard(view: View) {
view.requestFocus()
currentFocus?.windowToken?.let {
(getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager?)
?.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
}
}

感谢上帝,它在11年后得到了官方支持
首先将依赖实现“androidx.core:core-ktx:1.7.0”添加到appgradle
然后从ViewCompat或WindowCompat类获取InsetsController。
最后使用InsetsController的hide()和show()函数
已编辑添加对Dialog的支持。在BottomSheetDialog中提供@隆德夫。使用更安全的方式获取活动,而不是直接从上下文中强制转换。
import android.app.Activity
import android.app.Dialog
import android.content.Context
import android.content.ContextWrapper
import android.view.View
import androidx.core.view.ViewCompat
import androidx.core.view.WindowCompat
import androidx.core.view.WindowInsetsCompat
import androidx.fragment.app.Fragment
fun View.showKeyboard() = ViewCompat.getWindowInsetsController(this)?.show(WindowInsetsCompat.Type.ime())
fun View.hideKeyboard() = ViewCompat.getWindowInsetsController(this)?.hide(WindowInsetsCompat.Type.ime())
fun Dialog.showKeyboard() = window?.decorView?.showKeyboard()
fun Dialog.hideKeyboard() = window?.decorView?.hideKeyboard()
fun Context.showKeyboard() = getActivity()?.showKeyboard()
fun Context.hideKeyboard() = getActivity()?.hideKeyboard()
fun Fragment.showKeyboard() = activity?.showKeyboard()
fun Fragment.hideKeyboard() = activity?.hideKeyboard()
fun Activity.showKeyboard() = WindowCompat.getInsetsController(window, window.decorView)?.show(WindowInsetsCompat.Type.ime())
fun Activity.hideKeyboard() = WindowCompat.getInsetsController(window, window.decorView)?.hide(WindowInsetsCompat.Type.ime())
fun Context.getActivity(): Activity? {
return when (this) {
is Activity -> this
is ContextWrapper -> this.baseContext.getActivity()
else -> null
}
}
下面是旧的anwser
下面是github上的简单项目
import android.app.Activity
import android.app.Dialog
import android.content.Context
import android.content.ContextWrapper
import android.view.View
import androidx.core.view.ViewCompat
import androidx.core.view.WindowCompat
import androidx.core.view.WindowInsetsCompat
import androidx.fragment.app.Fragment
fun View.showKeyboard() = ViewCompat.getWindowInsetsController(this)?.show(WindowInsetsCompat.Type.ime())
fun View.hideKeyboard() = ViewCompat.getWindowInsetsController(this)?.hide(WindowInsetsCompat.Type.ime())
fun Dialog.showKeyboard() = window?.decorView?.showKeyboard()
fun Dialog.hideKeyboard() = window?.decorView?.hideKeyboard()
fun Context.showKeyboard() = getActivity()?.showKeyboard()
fun Context.hideKeyboard() = getActivity()?.hideKeyboard()
fun Fragment.showKeyboard() = activity?.showKeyboard()
fun Fragment.hideKeyboard() = activity?.hideKeyboard()
fun Activity.showKeyboard() = WindowCompat.getInsetsController(window, window.decorView)?.show(WindowInsetsCompat.Type.ime())
fun Activity.hideKeyboard() = WindowCompat.getInsetsController(window, window.decorView)?.hide(WindowInsetsCompat.Type.ime())
fun Context.getActivity(): Activity? {
return when (this) {
is Activity -> this
is ContextWrapper -> this.baseContext.getActivity()
else -> null
}
}
非常简单的方法
我在所有的项目中都这样做,并且像做梦一样工作。在声明layout.xml中,只需添加以下一行:
android:focusableInTouchMode="true"
完整代码示例:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content">
</ListView>
</android.support.constraint.ConstraintLayout>
public void hideKeyboard()
{
if(getCurrentFocus()!=null)
{
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}
}
public void showKeyboard(View mView) {
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
mView.requestFocus();
inputMethodManager.showSoftInput(mView, 0);
}
there are two ways to do so...
method 1:in manifest file
define the line **android:windowSoftInputMode="adjustPan|stateAlwaysHidden"** of code in your manifest.xml file as below...
<activity
android:name="packagename.youactivityname"
android:screenOrientation="portrait"
android:windowSoftInputMode="adjustPan|stateAlwaysHidden" />
Method 2 : in Activity or Java class
if(getCurrentFocus()!=null) {
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE)`enter code here`;
inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}
它会work....@ASK
对于科特林爱好者。我创建了两个扩展函数。为了隐藏键盘的乐趣,您可以将edittext的实例作为视图传递。
fun Context.hideKeyboard(view: View) {
(getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager)?.apply {
hideSoftInputFromWindow(view.windowToken, 0)
}
}
fun Context.showKeyboard() {
(getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager)?.apply {
toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY)
}
}
