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?

如果您需要在片段中隐藏键盘,则此方法有效。
public static void hideSoftKeyboard(Context context, View view) {
if (context != null && view != null) {
InputMethodManager imm = (InputMethodManager) context.getSystemService(Activity.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
对于视图,只需传入
getView() method
其他回答
您可以使用InputMethodManager强制Android隐藏虚拟键盘,调用hideSoftInputFromWindow,传入包含焦点视图的窗口的标记。
// Check if no view has focus:
View view = this.getCurrentFocus();
if (view != null) {
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
这将在所有情况下强制隐藏键盘。在某些情况下,您需要将InputMethodManager.HIDE_IMPLICIT_ONLY作为第二个参数传递,以确保仅在用户未显式强制显示键盘时(通过按住菜单)隐藏键盘。
注意:如果您想在Kotlin中执行此操作,请使用:上下文getSystemService(Context.INPUT_METHOD_SERVICE)作为InputMethodManager
Kotlin语法
// Only runs if there is a view that is currently focused
this.currentFocus?.let { view ->
val imm = getSystemService(Context.INPUT_METHOD_SERVICE) as? InputMethodManager
imm?.hideSoftInputFromWindow(view.windowToken, 0)
}
there are two ways to do so...
method 1:in manifest file
define the line **android:windowSoftInputMode="adjustPan|stateAlwaysHidden"** of code in your manifest.xml file as below...
<activity
android:name="packagename.youactivityname"
android:screenOrientation="portrait"
android:windowSoftInputMode="adjustPan|stateAlwaysHidden" />
Method 2 : in Activity or Java class
if(getCurrentFocus()!=null) {
InputMethodManager inputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE)`enter code here`;
inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}
它会work....@ASK
/**

* Hide I Said!!!

*/
public static boolean hideSoftKeyboard(@NonNull Activity activity) {
View currentFocus = activity.getCurrentFocus();
if (currentFocus == null) {
currentFocus = activity.getWindow().getDecorView();
if (currentFocus != null) {
return getSoftInput(activity).hideSoftInputFromWindow(currentFocus.getWindowToken(), 0, null);
}
}
return false;
}
public static boolean hideSoftKeyboard(@NonNull Context context) {
if(Activity.class.isAssignableFrom(context.getClass())){
return hideSoftKeyboard((Activity)context);
}
return false;
}
public static InputMethodManager getSoftInput(@NonNull Context context) {
return (InputMethodManager) context.getSystemService(Activity.INPUT_METHOD_SERVICE);
}
这应该是有效的:
public class KeyBoard {
public static void show(Activity activity){
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY); // show
}
public static void hide(Activity activity){
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0); // hide
}
public static void toggle(Activity activity){
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
if (imm.isActive()){
hide(activity);
} else {
show(activity);
}
}
}
KeyBoard.toggle(activity);
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);
}
}
