EditText软数字键盘有时不允许数字 [英] EditText soft numeric keyboard sometimes does not allow digits

问题描述

以下代码生成一个EditText(目标版本23).我已经为此工作了大约8个小时，并且收到了一些建议，但我认为以前没有人见过，所以我仍然坚持.

The following code produces an EditText (target version 23). I've been working on this for about 8 hours, and have received some suggestions, but I don't think anyone has ever seen this before, so I remain stuck.

1. 单击该字段.
2. A/N软键盘打开.
3. 单击123?左下角的按钮.数字软键盘打开.
4. 按任意数字.什么都没发生.
5. 长按5，将"5/8"添加到文本字段中.
6. 按任意特殊字符，例如@.它可能会添加到该字段中.
7. 清除字段.键入"for"，按123 ?，现在将要输入数字.
8. 清除字段.键入"for?"，然后按123 ?，则不输入数字.

我添加了一个TextWatcher.如果数字未发布，则TextWatcher也不会看到它们.

I added a TextWatcher. If the digits didn't post, the TextWatcher didn't see them either.

EditText bottomT = new EditText(model);
bottomT.setTextSize(14);
bottomT.setHint("ZIP");  
bottomT.setHintTextColor(Color.BLACK);
bottomT.setBackgroundColor(Color.WHITE);
bottomT.setTextColor(Color.BLACK);
// bottomT.setInputType(InputType.TYPE_CLASS_NUMBER)  Didn't make any difference.
// bottomT.setRawInputType(InputType.TYPE_CLASS_NUMBER)  Didn't make any difference.
// bottomT.setText("", TextView.BufferType.EDITABLE);  DIdn't make a difference
bottomT.setText(""); 

推荐答案

EditText行为异常，因为在我的自定义ViewGroup中，我拥有

EditText is misbehaving because in my custom ViewGroup I had

 protected void onLayout(boolean changed, int l, int t, int r, int b)
{
....
     child.layout(child.getLeft(), child.getTop(),
                    child.getLeft() + child.getMeasuredWidth(),
                    child.getTop() + child.getMeasuredHeight());

     child.setRight(somevalue);   // CAUSES EDITTEXT PROBLEMS
     child.setBottom(somevalue);  // CAUSES EDITTEXT PROBLEMS

现在很清楚，我无法设置setRight()和setBottom()，但是也很清楚，EditText应该不会变得很奇怪.

It’s clear now that I can't setRight() and setBottom(), but it’s also clear that EditText should not get weird.

忽略退格键.

随机忽略数字键，但接受小数点.

Randomly ignore numeric keys, but accept the decimal point.

忽略newLine(Enter)键

Ignore the newLine(Enter) key

是否忽略哪个键取决于设备.三星Tab 4或Nexus 5 API 23 X86模拟器是了解这一点的好地方.

Which keys are ignored, or not, depends on the device. Samsung Tab 4 or the Nexus 5 API 23 X86 emulator are good places to see this.
