如果我们有一个EditText
并且它失去焦点(对于一个不需要键盘的元素),软键盘应该自动隐藏还是我们应该自己隐藏它?
我正在将焦点从AutoCompleteSearchView
(我的行为应该像EditText
一样)移动到Button
,requestFocus()
返回true,但是键盘没有别隐藏。

最好的方法是为EditText设置OnFocusChangeListener,然后将键盘中的代码添加到侦听器的OnFocusChange方法中。当EditText失去焦点时,Android将自动关闭键盘。
OnCreate方法中的类似内容:
EditText editText = (EditText) findViewById(R.id.textbox);
OnFocusChangeListener ofcListener = new MyFocusChangeListener();
editText.setOnFocusChangeListener(ofcListener);
然后添加类:
private class MyFocusChangeListener implements OnFocusChangeListener {
public void onFocusChange(View v, boolean hasFocus){
if(v.getId() == R.id.textbox && !hasFocus) {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
}
}

Android不会为您隐藏键盘。如果您希望在EditText
失去焦点时隐藏键盘,请尝试在该事件上使用这样的方法:
private void hideKeypad() {
EditText edtView = (EditText) findViewById(R.id.e_id);
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(edtView.getWindowToken(), 0);
}

试试这个
/**
* Hide keyboard on touch of UI
*/
public void hideKeyboard(View view) {
if (view instanceof ViewGroup) {
for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
View innerView = ((ViewGroup) view).getChildAt(i);
hideKeyboard(innerView);
}
}
if (!(view instanceof EditText)) {
view.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
hideSoftKeyboard(v);
return false;
}
});
}
}
/**
* Hide keyboard while focus is moved
*/
public void hideSoftKeyboard(View view) {
if (view != null) {
InputMethodManager inputManager = (InputMethodManager) contentsContext_
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (inputManager != null) {
if (android.os.Build.VERSION.SDK_INT < 11) {
inputManager.hideSoftInputFromWindow(view.getWindowToken(),
0);
} else {
if (this.getCurrentFocus() != null) {
inputManager.hideSoftInputFromWindow(this
.getCurrentFocus().getWindowToken(),
InputMethodManager.HIDE_NOT_ALWAYS);
}
view.clearFocus();
}
view.clearFocus();
}
}
}

试试这个,可能会解决你的问题。
private void hideKeyboard() {
InputMethodManager mImMan = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
mImMan.hideSoftInputFromWindow(mYourEdttxtName.getWindowToken(), 0);
}

已找到此问题的解决方案here
它在活动上使用DispatchTouchEvent,并且不会将每个EditText挂钩到FocusChange或Touch事件。
这是更好的解决方案。
我的Xamarin实现如下:
public override bool DispatchTouchEvent(MotionEvent ev)
{
if (ev.Action == MotionEventActions.Down)
{
var text = CurrentFocus as EditText;
if (text != null)
{
var outRect = new Rect();
text.GetGlobalVisibleRect(outRect);
if (outRect.Contains((int) ev.RawX, (int) ev.RawY)) return base.DispatchTouchEvent(ev);
text.ClearFocus();
HideSoftKeyboard();
}
}
return base.DispatchTouchEvent(ev);
}
protected void HideSoftKeyboard()
{
var inputMethodManager = (InputMethodManager) GetSystemService(InputMethodService);
inputMethodManager.HideSoftInputFromWindow(CurrentFocus.WindowToken, 0);
}

只需创建一个静态方法
public static void touchScreenAndHideKeyboardOnFocus(View view, final Activity activity) {
if (view instanceof EditText) {
view.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
if(activity != null) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
if (activity.getCurrentFocus() != null) {
inputMethodManager.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
}
}
}
});
}
if (view instanceof ViewGroup) {
for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
View innerView = ((ViewGroup) view).getChildAt(i);
touchScreenAndHideKeyboardOnFocus(innerView, activity);
}
}
}
view是布局的根视图..但是如果你的edittext中有另一个焦点监听器,请小心..

您可以覆盖dispatchTouchEvent
方法来实现它:
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
/**
* It gets into the above IF-BLOCK if anywhere the screen is touched.
*/
View v = getCurrentFocus();
if ( v instanceof EditText) {
/**
* Now, it gets into the above IF-BLOCK if an EditText is already in focus, and you tap somewhere else
* to take the focus away from that particular EditText. It could have 2 cases after tapping:
* 1. No EditText has focus
* 2. Focus is just shifted to the other EditText
*/
Rect outRect = new Rect();
v.getGlobalVisibleRect(outRect);
if (!outRect.contains((int)event.getRawX(), (int)event.getRawY())) {
v.clearFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
}
}
}
return super.dispatchTouchEvent( event );
}
奖励:如果EditText获得焦点,则触发事件的顺序为:
onFocusChange()
(如果其他edittext失去焦点)ACTION_DOWN
被称为onFocusChange()

我的问题解决了这个代码(在片段中)
LinearLayout linearLayoutApply=(LinearLayout)rootView.findViewById(id.LinearLayoutApply);
linearLayoutApply.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus)
{
hideKeyBoard(v);
}
}
});
hideKeyBoard
public void hideKeyBoard(View v)
{
InputMethodManager imm=(InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
}

这对我有用:
InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
