Android numeric password field
提问by Viktor Bre?an
I have an EditText field which needs to be a numeric password field. Everything works OK in portrait mode; not in landscape. When the user selects the EditText field, the UI zooms into the field and when I type all the characters are visible.
我有一个 EditText 字段,它需要是一个数字密码字段。在纵向模式下一切正常;不在风景中。当用户选择 EditText 字段时,UI 会放大该字段,并且当我键入时,所有字符都可见。
I need a numeric keyboard also. I tried setting the input type to text password|number. If I remove "number" option everything works right; otherwise no.
我也需要一个数字键盘。我尝试将输入类型设置为文本密码|数字。如果我删除“数字”选项,一切正常;否则没有。
Any suggestions?
有什么建议?

This problem can be solved without using deprecated android:password
. Use the following code snippet, but do not reverse the sequence of calls:
这个问题可以在不使用 deprecated 的情况下解决android:password
。使用以下代码片段,但不要颠倒调用顺序:
EditText editText = (EditText) findViewById(R.id.MyEditText);
editText.setInputType(InputType.TYPE_CLASS_NUMBER);
editText.setTransformationMethod(PasswordTransformationMethod.getInstance());

The simplest solution that I found for a numeric text entry that needed to be hidden (password style) was to use: android:inputType="numberPassword"
我为需要隐藏的数字文本条目(密码样式)找到的最简单的解决方案是使用: android:inputType="numberPassword"
Full example that worked for me:
对我有用的完整示例:
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="@style/MyLargeTextBox"
android:background="@android:drawable/editbox_background_normal"
android:id="@+id/txtWebServicePIN"
android:layout_row="3"
android:layout_column="2"
android:layout_columnSpan="2"
android:minWidth="100dp"
android:maxWidth="100dp"
android:inputType="numberPassword"
android:maxLength="6"/>

To fix the issue where the password is visible in the landscape mode full-screen editor (as Marcus described), you can add the following line to disable the full-screen editor:
要解决密码在横向模式全屏编辑器中可见的问题(如 Marcus 所述),您可以添加以下行以禁用全屏编辑器:
editText.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI);
You may also want to change the typeface to monospace to better emulate the text-password behavior:
您可能还想将字体更改为等宽字体以更好地模拟文本密码行为:
editText.setTypeface(Typeface.MONOSPACE);

android:password="true"
may solve your problem.

在 XML 中尝试此操作,清单文件中没有任何更改,
<EditText

I think you should use android:password="true"
and android:numeric="integer"
. But as the Android documentation states (in R.attr.html
, not in the TextView
docs), these are deprectated and you should use android:inputType
. inputType takes flag, so you can mix mulitple possibilities. And I think android:inputType="number | password"
should work for you.
我认为你应该使用android:password="true"
和android:numeric="integer"
。但正如 Android 文档所述(在R.attr.html
,而不是在TextView
文档中),这些已弃用,您应该使用android:inputType
. inputType 带有标志,因此您可以混合多种可能性。我认为android:inputType="number | password"
应该为你工作。
You should specify android:password="true"
if you want to support older devices too.
您应该指定android:password="true"
是否也想支持旧设备。
