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?

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);
}
}
}
其他回答
作为这一全面解决方案的替代方案,如果您想从任何地方关闭软键盘,而没有对用于打开键盘的(EditText)字段的引用,但仍然希望在该字段被聚焦时进行此操作,则可以使用(从“活动”):
if (getCurrentFocus() != null) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}
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);
}
}
final RelativeLayout llLogin = (RelativeLayout) findViewById(R.id.rl_main);
llLogin.setOnTouchListener(
new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent ev) {
InputMethodManager imm = (InputMethodManager) this.getSystemService(
Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);
return false;
}
});
这对我所有奇怪的键盘行为都有效
private boolean isKeyboardVisible() {
Rect r = new Rect();
//r will be populated with the coordinates of your view that area still visible.
mRootView.getWindowVisibleDisplayFrame(r);
int heightDiff = mRootView.getRootView().getHeight() - (r.bottom - r.top);
return heightDiff > 100; // if more than 100 pixels, its probably a keyboard...
}
protected void showKeyboard() {
if (isKeyboardVisible())
return;
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
if (getCurrentFocus() == null) {
inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
} else {
View view = getCurrentFocus();
inputMethodManager.showSoftInput(view, InputMethodManager.SHOW_FORCED);
}
}
protected void hideKeyboard() {
if (!isKeyboardVisible())
return;
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
View view = getCurrentFocus();
if (view == null) {
if (inputMethodManager.isAcceptingText())
inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_NOT_ALWAYS, 0);
} else {
if (view instanceof EditText)
((EditText) view).setText(((EditText) view).getText().toString()); // reset edit text bug on some keyboards bug
inputMethodManager.hideSoftInputFromInputMethod(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
}
下面是隐藏和显示方法。

fun hideKeyboard(activity: Activity) {
val v = activity.currentFocus
val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
assert(v != null)
imm.hideSoftInputFromWindow(v!!.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
}
private fun showKeyboard(activity: Activity) {
val v = activity.currentFocus
val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
assert(v != null)
imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT)
}
Java
public static void hideKeyboard(Activity activity) {
View v = activity.getCurrentFocus();
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null && v != null;
imm.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
