将 AlertDialog.Builder 与 EditText 一起使用时,软键盘不会弹出
我正在使用 AlertDialog.Builder 来创建一个输入框,并使用 EditText 作为输入方法。
不幸的是,尽管 EditText 处于焦点状态,但软键盘不会弹出,除非您再次明确触摸它。
有没有办法强制它弹出?
我已尝试以下操作,在 (AlertDialog.Builder).show(); 之后,但无济于事。
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(input, InputMethodManager.SHOW_FORCED);
有人可以帮忙吗?
谢谢!!
I am using AlertDialog.Builder in order to create an input box, with EditText as the input method.
Unfortunately, the Soft Keyboard doesn't pop, although the EditText is in focus, unless you explicitly touch it again.
Is there a way to force it to pop?
I've tried the following, after the (AlertDialog.Builder).show(); but for no avail.
InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
mgr.showSoftInput(input, InputMethodManager.SHOW_FORCED);
Anyone can help?
Thanks!!

试试这个,它对我有用
Try this, its working for me
我找到了一个简单可靠的解决方案,如果你有一个复杂的布局,可编辑字段不在根目录中,只需在对话框布局的根目录中放置一个隐藏的 EditText ,
这基本上是为了欺骗 这部分兼容/androidx。
我曾经使用上面的
onResume
解决方案,但我无法使用AlertDialog.Builder()
的更简单的 API 来删除AppCompatDialogFragment
的使用但现在我可以简单地使用更简单的 API。I found an easy and reliable solution to this, just put a hidden EditText on root of your dialog layout if you got a complex layout which an editable field isn't in root,
This is basically to trick this part of compat/androidx.
I used to use
onResume
solution above but with that I couldn't use simpler API ofAlertDialog.Builder()
to remove the use ofAppCompatDialogFragment
but now I can simply use the easier API.试试这个,它对我有用
如果你想显示软键盘:
如果你想隐藏它:
Try this, its working for me
If you want to display soft keyboard:
And if you want to hide the it:
我做了这样的事情
I've made such a thing
我已经设法像这样解决它:
I've managed to solve it like this:
我发现相同的代码在平板电脑上可以正常工作,键盘确实会弹出,但在手机上却不会,因此进一步研究,似乎指向“调整”选项。
我正在用这个,感觉干净很多。
I found out that the same code works properly on Tablet, the keyboard does pop up, but on Phone it doesn't, so researching further, seems to point to the "adjust" option.
I am using this, feels much cleaner.
就我而言,在显示对话框时能够显示键盘的唯一方法是添加到我的
DialogFragment
:请注意 SOFT_INPUT_STATE_ALWAYS_VISIBLE 而不是 SOFT_INPUT_STATE_VISIBLE.
来自文档:
In my case the only way I was able to show the keyboard when the Dialog was shown was by adding to my
DialogFragment
:Note the SOFT_INPUT_STATE_ALWAYS_VISIBLE instead of SOFT_INPUT_STATE_VISIBLE.
From documentation:
此处给出了更好的解决方案。
没有解决方法。
EditText
的行为符合预期。A much better solution is given here.
No workaround.
EditText
behaves as expected.就我而言,当我在显示对话框之前(创建对话框之后)设置 SoftInputMode 时,它没有显示。下面的代码对我有用,我在显示对话框后设置了 SoftInputMode。
Kotlin:
Java:
我希望这可以帮助任何与我遇到同样问题的人。
In my case, the SoftInputMode wasn't getting displayed when I set it which was before showing the dialog (after creating it). The below code worked for me where I set the SoftInputMode after showing the dialog.
Kotlin:
Java:
I hope this helps anyone who was having the same problem as me.
当您调用
showDialog()
来显示在onCreateDialog()
中使用AlertDialog
创建的对话框时,您应该将代码放在
onPrepareDialog() 中:
When you call
showDialog()
to show a Dialog created usingAlertDialog
inonCreateDialog()
You should put the code in
onPrepareDialog()
:此处已经回答了这个问题。使用 OnFocusChangeListener 对我有用。
This was answered here already. Using an OnFocusChangeListener worked for me.
调用 AlertDialog.onCreate 后添加 EditText 时会出现此问题。
https://developer.android.com/reference/androidx/appcompat/应用程序/AlertDialog.Builder
您需要清除 FLAG_ALT_FOCUSABLE_IM 标志。
因为AlertDialog.show是在DialogFragment.onStart中调用的,所以可以在DialogFragment.onStart中插入代码。
或者,如果您不使用 DialogFragment,则可以使用 Dialog.setOnShowListener。
This problem occurs when EditText is added after AlertDialog.onCreate is called.
https://developer.android.com/reference/androidx/appcompat/app/AlertDialog.Builder
You need to clear the FLAG_ALT_FOCUSABLE_IM flag.
Because AlertDialog.show is called in the DialogFragment.onStart, you can insert the code in the DialogFragment.onStart.
Or you can use the Dialog.setOnShowListener if you do not use a DialogFragment.
