EditText上不接受数字输入 [英] EditText does not accept digits as input

问题描述

在的EditText 视图 ID =价格有一个 inputType =numberDecimal 不接受任何数字，但只接受小数点后一位数。另的EditText 视图 ID =存储没有 inputType 确定，但有两个问题。如果视图没有输入，然后进入键盘数字没有做任何事情。有一个数字被接受的唯一方法是，如果它紧跟字母或其它数字。我使用的是默认的安卓键盘。布局正在膨胀中的 onCreateView（） SherlockFragment 的子类的方法。难道这是一个问题，在的EditText 视图的行为 SherlockFragment ？我有一个用于膨胀SherlockFragmentActivity的一个子类相似的布局，以及的EditText 的意见都将正常进行。有谁知道什么可能会造成这个问题？

The EditText view with id="price" has an inputType="numberDecimal" that does not accept any digits but will only accept one decimal point. The other EditText view with id="store" has no inputType set but has two issues. If the view has no input then entering a digit from the keyboard doesn't do anything. The only way to have a digit be accepted is if it immediately follows either a letter or another digit. I am using the default Android keyboard. The layout is being inflated in the onCreateView() method of a subclass of SherlockFragment. Could this be an issue with the EditText view behavior inside a SherlockFragment? I have a similar layout that is used to inflate a subclass of 'SherlockFragmentActivity', and those EditText views behave normally. Does anyone know what could be causing this issue?

更新

当我测试了在Android V4.3，它具有搞砸了（不接受数字输入）的行为。不过，我测试了它在Android V4.1.2，它接受数字输入。有什么关于这两个版本的不同，只要EditText上的行为？

Update

When I tested this on Android v4.3, it has the messed up (not accepting digits as input) behavior. However, I tested it on Android v4.1.2, and it accepts digits as input. Is there something different about these two versions as far as EditText behavior?

推荐答案

原来，这个问题是不是与安卓inputType 设置的，但有一个较高的ViewGroup在视图层次结构。这是用来充气的布局 SherlockFragment 是一个孩子在一个更复杂的布局。

It turns out the issue wasn't with the android:inputType that was set, but with a ViewGroup higher up in the view hierarchy. The layout which is used to inflate the SherlockFragment was a child in a more complex layout.

几个家长了视图层次存在的的FrameLayout 的ViewGroup的子类名为 DragLayer 。该 DragLayer 类实现的接口名为 DragController.DragListener 这有一个方法 dispatchKeyEvent（KeyEvent的事件）。这种方法在 DragLayer 使用 @覆盖标记但没有叫 super.dispatchKeyEvent（事件）。加入这一行的code后，然后单击键盘上的数字的事件没有得到消耗，所有的工作了。

A few parents up the view hierarchy there was a subclass of the FrameLayout ViewGroup called DragLayer. The DragLayer class implemented an Interface called DragController.DragListener which has a method dispatchKeyEvent(KeyEvent event). This method in DragLayer uses the @Override notation however did not call super.dispatchKeyEvent(event). After adding this line of code, then the event of clicking a digit on the keyboard did not get consumed and all works now.
