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?

当前回答
我使用Kotlin扩展来显示和隐藏键盘。
fun View.showKeyboard() {
this.requestFocus()
val inputMethodManager = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT)
}
fun View.hideKeyboard() {
val inputMethodManager = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
inputMethodManager.hideSoftInputFromWindow(windowToken, 0)
}

一个简单的解决方法是只编辑Text.setEnabled(false);editText.setEnabled(true);在Button onClick()方法中。
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
}
}
Kotlin版本:
fun showKeyboard(mEtSearch: EditText, context: Context) {
mEtSearch.requestFocus()
val imm: InputMethodManager =
context.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
imm.showSoftInput(mEtSearch, 0)
}
public final class UtilsKeyboard {
/**
* Sets the cursor at the end of this edit text and shows a keyboard
*/
public static void focusKeyboard(@NonNull EditText editText) {
editText.requestFocus();
editText.setSelection(editText.getText().length());
showKeyboard(editText);
}
private static void showKeyboard(@NonNull View view) {
final InputMethodManager manager = (InputMethodManager) view.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
if (manager != null) {
manager.showSoftInput(view, InputMethodManager.SHOW_FORCED);
}
}
public static boolean hideKeyboard(@NonNull Window window) {
View view = window.getCurrentFocus();
return hideKeyboard(window, view);
}
private static boolean hideKeyboard(@NonNull Window window, @Nullable View view) {
if (view == null) {
return false;
}
InputMethodManager inputMethodManager = (InputMethodManager) window.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
if (inputMethodManager != null) {
return inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
return false;
}
public static boolean hideKeyboard(@Nullable View view) {
if (view == null) {
return false;
}
InputMethodManager inputMethodManager = (InputMethodManager) view.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
if (inputMethodManager != null) {
return inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
return false;
}
/**
* This will hide the keyboard and unfocus any focused view.
*/
public static void unfocusKeyboard(@NonNull Window window) {
// When showing the bottom menu, make sure the keyboard isn't and that no view has focus
hideKeyboard(window);
final View focused = window.getCurrentFocus();
if (focused != null) focused.clearFocus();
}}
简单的方法家伙:试试这个。。。
private void closeKeyboard(boolean b) {
View view = this.getCurrentFocus();
if(b) {
if (view != null) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
else {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(view, 0);
}
}
