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
private void hideSoftKeyboard() {
View view = getView();
if (view != null) {
InputMethodManager inputMethodManager = (InputMethodManager) getActivity()
.getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
其他回答
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);
}
}
}
科特林
class KeyboardUtils{
companion object{
fun hideKeyboard(activity: Activity) {
val imm: InputMethodManager = activity.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
var view: View? = activity.currentFocus
if (view == null) {
view = View(activity)
}
imm.hideSoftInputFromWindow(view.windowToken, 0)
}
}
}
那就在你需要的地方打电话
碎片
KeyboardUtils.hideKeyboard(requireActivity())
活动
KeyboardUtils.hideKeyboard(this)
对于Xamarin.Android:
public void HideKeyboard()
{
var imm = activity.GetSystemService(Context.InputMethodService).JavaCast<InputMethodManager>();
var view = activity.CurrentFocus ?? new View(activity);
imm.HideSoftInputFromWindow(view.WindowToken, HideSoftInputFlags.None);
}
当您想手动隐藏键盘时,单击按钮:
/**
* Hides the already popped up keyboard from the screen.
*
*/
public void hideKeyboard() {
try {
// use application level context to avoid unnecessary leaks.
InputMethodManager inputManager = (InputMethodManager) getApplicationContext().getSystemService(Context.INPUT_METHOD_SERVICE);
assert inputManager != null;
inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
} catch (Exception e) {
e.printStackTrace();
}
}
当您想在屏幕上除编辑文本以外的任何地方隐藏键盘时在活动中重写此方法:
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
View view = getCurrentFocus();
if (view != null && (ev.getAction() == MotionEvent.ACTION_UP || ev.getAction() == MotionEvent.ACTION_MOVE) && view instanceof EditText && !view.getClass().getName().startsWith("android.webkit.")) {
int scrcoords[] = new int[2];
view.getLocationOnScreen(scrcoords);
float x = ev.getRawX() + view.getLeft() - scrcoords[0];
float y = ev.getRawY() + view.getTop() - scrcoords[1];
if (x < view.getLeft() || x > view.getRight() || y < view.getTop() || y > view.getBottom())
((InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow((this.getWindow().getDecorView().getApplicationWindowToken()), 0);
}
return super.dispatchTouchEvent(ev);
}
调用此方法以隐藏软键盘
public void hideKeyBoard() {
View view1 = this.getCurrentFocus();
if(view!= null){
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view1.getWindowToken(), 0);
}
}
