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?

Meier的解决方案也适用于我。在我的例子中,我的应用程序的顶层是一个选项卡宿主,我想在切换选项卡时隐藏关键字-我从选项卡宿主视图获取窗口令牌。
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
public void onTabChanged(String tabId) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(tabHost.getApplicationWindowToken(), 0);
}
}

要在应用程序启动时显示键盘:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN | WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
view.requestFocus();
new Handler().postDelayed(new Runnable() {
public void run() {
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
}
}, 1000);
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。
如果你使用Kotlin开发你的应用程序,这真的很容易做到。
添加此扩展功能:
对于活动:
fun Activity.hideKeyboard() {
val inputManager = getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
val view = currentFocus
if (view != null) {
inputManager.hideSoftInputFromWindow(view.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
}
}
对于片段:
fun Fragment.hideKeyboard() {
activity?.let {
val inputManager = it.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
val view = it.currentFocus
if (view != null) {
inputManager.hideSoftInputFromWindow(view.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
}
}
}
现在,您可以简单地调用片段或活动:
hideKeyboard()
简单的方法是在EditText视图中设置以下属性。
android:imeOptions="actionDone"
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();
}}
