Android 中的 EditText onClickListener
我想要一个 EditText,它在按下时创建一个 DatePicker。所以我编写了以下代码:
mEditInit = (EditText) findViewById(R.id.date_init);
mEditInit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showDialog(DATEINIT_DIALOG);
}
});
但是当我按下 EditText 时,操作是典型的:光标等待输入文本,而不是显示我想要的对话框。
I want an EditText which creates a DatePicker when is pressed. So I write the following code:
mEditInit = (EditText) findViewById(R.id.date_init);
mEditInit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showDialog(DATEINIT_DIALOG);
}
});
But when I press the EditText the action is the typical: a cursor waiting for typing text instead show the Dialog I want.

当 EditText 获得焦点时,键盘似乎会弹出。为了防止这种情况,请将 focusable 设置为 false:
此行为可能因不同制造商的 Android 操作系统风格而异,但在
我测试过的设备我发现这已经足够了。如果键盘仍然弹出,使用提示而不是文本似乎也有帮助:
完成此操作后,您的点击侦听器应该按预期工作:
The keyboard seems to pop up when the EditText gains focus. To prevent this, set focusable to false:
This behavior can vary on different manufacturers' Android OS flavors, but on the
devices I've tested I have found this to to be sufficient. If the keyboard still pops up, using hints instead of text seems to help as well:
Once you've done this, your on click listener should work as desired:
通常,您希望与
EditText
的正常行为具有最大的兼容性。因此,您不应该使用
android:focusable="false"
,因为,是的,视图将不再可聚焦,这看起来很糟糕。例如,背景可绘制对象将不再显示其“按下”状态。您应该执行以下操作:
通过将输入类型设置为
TYPE_NULL
,可以防止软件键盘弹出。通过设置
OnClickListener
和OnFocusChangeListener
,您可以确保当用户单击EditText
字段时对话框始终打开,无论是在它获得焦点(第一次单击)和后续单击。仅设置
android:inputType="none"
或setInputType(InputType.TYPE_NULL)
并不总是足够的。对于某些设备,您还应该在 XML 中设置android:editable="false"
,尽管它已被弃用。如果它不再起作用,它将被忽略(因为所有 XML 属性都不支持)。Normally, you want maximum compatibility with
EditText
's normal behaviour.So you should not use
android:focusable="false"
as, yes, the view will just not be focusable anymore which looks bad. The background drawable will not show its "pressed" state anymore, for example.What you should do instead is the following:
By setting the input type to
TYPE_NULL
, you prevent the software keyboard from popping up.By setting the
OnClickListener
andOnFocusChangeListener
, you make sure that your dialog will always open when the user clicks into theEditText
field, both when it gains focus (first click) and on subsequent clicks.Just setting
android:inputType="none"
orsetInputType(InputType.TYPE_NULL)
is not always enough. For some devices, you should setandroid:editable="false"
in XML as well, although it is deprecated. If it does not work anymore, it will just be ignored (as all XML attributes that are not supported).我也有同样的问题。代码很好,但请确保将 EditText 的可聚焦值更改为 false。
我希望这对遇到类似问题的人有所帮助!
I had this same problem. The code is fine but make sure you change the focusable value of the EditText to false.
I hope this helps anyone who has had a similar problem!
EditText
的默认工作方式:第一次单击时它会聚焦,第二次单击时它会处理
onClickListener
因此您需要禁用焦点。然后,在第一次单击时,onClickListener
将进行处理。为此,您需要将此
android:focusableInTouchMode="false"
属性添加到EditText
中。就是这样!像这样的东西:
Default working of
EditText
:On first click it focuses and on second click it handles
onClickListener
so you need to disable focus. Then on first click theonClickListener
will handle.To do that you need to add this
android:focusableInTouchMode="false"
attribute to yourEditText
. That's it!Something like this:
这是我实现的解决方案

您自己查看差异。
问题是因为(就像 RickNotFred 所说)TextView 显示日期和时间。通过 DatePicker 进行编辑。 TextEdit 不用于其主要目的。
如果你想让DatePicker重新弹出,你需要输入delete(第一种情况)或de focus(第二种情况)。

Here is the solution I implemented
OR
See the differences by yourself.
Problem is since (like RickNotFred said) TextView to display the date & edit via the DatePicker. TextEdit is not used for its primary purpose.
If you want the DatePicker to re-pop up, you need to input delete (1st case) or de focus (2nd case).

如果您在 EditText 上使用 OnClick 操作,例如:
java:
或 kotlin:
所以,如果您将以下行放入
EditText
的xml
中:例如:
或用于 MaterialDesign
If you use OnClick action on EditText like:
java:
or kotlin:
So, it will work perfectly if you put into
xml
of yourEditText
the following lines:For example:
or for MaterialDesign

好话题。嗯,我已经这样做了。
在 XML 文件中:
在 Java 代码中:

Nice topic. Well, I have done so.
In XML file:
In Java-code:
恕我直言,我不同意 RickNotFred 的说法:
当用户按下 EditText 时显示一个编辑日期的对话框与默认情况非常相似,即显示键盘或数字小键盘。日期与 EditText 一起显示的事实向用户表明该日期可能会更改。将日期显示为不可编辑的 TextView 向用户发出该日期不可更改的信号。
IMHO I disagree with RickNotFred's statement:
Displaying a dialog to edit the date when the use presses the an EditText is very similar to the default, which is to display a keyboard or a numeric key pad. The fact that the date is displayed with the EditText signals to the user that the date may be changed. Displaying the date as a non-editable TextView signals to the user that the date may not be changed.
以下内容非常适合我。
首先将日期选择器小部件的输入设置为“无”,以防止弹出软键盘:
然后添加这些事件侦听器以显示包含日期选择器的对话框:
最后一件事。为了确保从日期选择器中正确复制输入的日、月或年,请在检索值之前调用
datePicker.clearFocus()
,例如通过getMonth()
。The following works perfectly for me.
First set your date picker widget's input to 'none' to prevent the soft keyboard from popping up:
Then add these event listeners to show the dialog containing the date picker:
One last thing. To make sure typed days, months, or years are correctly copied from the date picker, call
datePicker.clearFocus()
before retrieving the values, for instance viagetMonth()
.这对我有用:
This Works For me:
这是对我有用的
设置可编辑为 false
/>
然后为OnFocusChange添加事件监听器
Here is what worked for me
Set editable to false
/>
Then add an event listener for OnFocusChange
正如 Dillon Kearns 所建议的,将 focusable 设置为 false 效果很好。
但如果您的目标是在单击 EditText 时取消键盘,您可能需要使用:
As Dillon Kearns suggested, setting focusable to false works fine.
But if your goal is to cancel the keyboard when EditText is clicked, you might want to use:
为什么没有人提到
setOnTouchListener
?使用 setOnTouchListener 非常简单,如果侦听器已使用该事件,则返回 true,否则返回 false。Why did not anyone mention
setOnTouchListener
? UsingsetOnTouchListener
is easy and all right, and just return true if the listener has consumed the event, false otherwise.使用 OnFocusChangeListener 的解决方案的问题在于,它们将任何焦点增益解释为单击。这并不是 100% 正确:您的 EditText 可能会通过点击以外的其他方式获得焦点。
如果您严格关心点击并且想要一致地检测点击(无论焦点如何),您可以使用
GestureDetector
:The problem with solutions using OnFocusChangeListener is that they interpret any focus gain as a click. This is not 100% correct: your EditText might gain focus from something else than a click.
If you strictly care about click and want to detect click consistently (regardless of focus), you can use a
GestureDetector
:对于 kotlin,你可以使用这个
For kotlin, you could use this
对于 EditText 或 TextInputEditText 使用以下属性
For EditText or TextInputEditText Use the Below Properties
