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?

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
}
}
其他回答
只需在BaseActivity和BaseFragment中为整个应用程序创建通用方法
在onCreate()中初始化inputMethodManager
inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
使用此方法隐藏和显示键盘
public void hideKeyBoard(View view) {
if (view != null) {
inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
public void showKeyboard(View view, boolean isForceToShow) {
if (isForceToShow)
inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
else if (view != null)
inputMethodManager.showSoftInput(view, 0);
}
public static void hideSoftKeyboard(Activity activity) {
InputMethodManager inputMethodManager = (InputMethodManager) activity
.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus()
.getWindowToken(), 0);
}
在某些情况下,除了所有其他方法外,这种方法都可以工作。这节省了我的一天:)
public static void hideSoftKeyboard(Activity activity) {
if (activity != null) {
InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
if (activity.getCurrentFocus() != null && inputManager != null) {
inputManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
inputManager.hideSoftInputFromInputMethod(activity.getCurrentFocus().getWindowToken(), 0);
}
}
}
public static void hideSoftKeyboard(View view) {
if (view != null) {
InputMethodManager inputManager = (InputMethodManager) view.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
if (inputManager != null) {
inputManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
}
在如此的搜索中,我找到了一个适合我的答案
// Show soft-keyboard:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
// Hide soft-keyboard:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
试试这个
简单,您可以在活动中调用
public static void hideKeyboardwithoutPopulate(Activity activity) {
InputMethodManager inputMethodManager =
(InputMethodManager) activity.getSystemService(
Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(
activity.getCurrentFocus().getWindowToken(), 0);
}
在您的主活动中调用
hideKeyboardwithoutPopulate(MainActivity.this);
