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?

一些科特林代码:
从“活动”中隐藏键盘:
(currentFocus ?: View(this))
.apply { (getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager)
.hideSoftInputFromWindow(windowToken, 0) }

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
}
}
碎片形式的科特林溶液:
fun hideSoftKeyboard() {
val view = activity?.currentFocus
view?.let { v ->
val imm =
activity?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager // or context
imm.hideSoftInputFromWindow(v.windowToken, 0)
}
}
检查您的清单是否没有与活动关联的此参数:
android:windowSoftInputMode="stateAlwaysHidden"
记下所有这些答案,简单地说,我写了一个常用的方法:
/**
* hide soft keyboard in a activity
* @param activity
*/
public static void hideKeyboard (Activity activity){
activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
if (activity.getCurrentFocus() != null) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
}
试试这个
public void disableSoftKeyboard(final EditText v) {
if (Build.VERSION.SDK_INT >= 11) {
v.setRawInputType(InputType.TYPE_CLASS_TEXT);
v.setTextIsSelectable(true);
} else {
v.setRawInputType(InputType.TYPE_NULL);
v.setFocusable(true);
}
}
我正在使用自定义键盘输入十六进制数,因此无法显示IMM键盘。。。
在v3.2.4_r1中,添加了setSoftInputShownOnFocus(布尔显示)来控制天气或在TextView获得焦点时不显示键盘,但它仍然隐藏,因此必须使用反射:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
try {
Method method = TextView.class.getMethod("setSoftInputShownOnFocus", boolean.class);
method.invoke(mEditText, false);
} catch (Exception e) {
// Fallback to the second method
}
}
对于较旧的版本,我使用OnGlobalLayoutListener获得了非常好的结果(但远非完美),在根视图的ViewTreeObserver的帮助下添加,然后检查键盘是否显示如下:
@Override
public void onGlobalLayout() {
Configuration config = getResources().getConfiguration();
// Dont allow the default keyboard to show up
if (config.keyboardHidden != Configuration.KEYBOARDHIDDEN_YES) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(mRootView.getWindowToken(), 0);
}
}
最后一个解决方案可能会在一秒钟内显示键盘,并干扰选择手柄。
当键盘进入全屏时,不会调用onGlobalLayout。要避免这种情况,请在TextView XML声明中使用TextView#setImeOptions(int)或:
android:imeOptions="actionNone|actionUnspecified|flagNoFullscreen|flagNoExtractUi"
更新:刚刚发现对话框用于从不显示键盘,并且在所有版本中都有效:
getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
