以编程方式为EditText设置inputType？

How do we set the input type for an EditText programatically? I'm trying:

我们如何以编程方式设置EditText的输入类型?我尝试着:

mEdit.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);

it doesn't seem to have any effect.

它似乎没有任何影响。

9 个解决方案

#1

According to the TextView docs, the programmatic version of android:password is setTransformationMethod(), not setInputType(). So something like:

根据TextView文档,android:password的编程版本是setTransformationMethod(),而不是setInputType()。所以类似于:

mEdit.setTransformationMethod(PasswordTransformationMethod.getInstance());

should do the trick.

应该做的伎俩。

#2

For setting the input type for an EditText programmatically, you have to specify that input class type is text.

要以编程方式设置EditText的输入类型,必须指定输入类类型为text。

editPass.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);

#3

i've solve all with

我已经解决了所有问题

.setInputType(InputType.TYPE_CLASS_NUMBER);

for see clear data and

看清楚数据和

.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

for see the dots (if the data is a number, it isn't choice che other class)

看点(如果数据是数字,则不是选择其他类)

#4

To only allow numbers:

仅允许数字:

password1.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_CLASS_NUMBER);

To transform (hide) the password:

要转换(隐藏)密码:

password1.setTransformationMethod(PasswordTransformationMethod.getInstance());

Other options besides TYPE_CLASS_TEXT can be found in the documentation.

除了TYPE_CLASS_TEXT之外的其他选项可以在文档中找到。

This may be of help to others like me who wanted to toggle between password and free-text mode. I tried using the input methods suggested but it only worked in one direction. I could go from password to text but then I could not revert. For those trying to handle a toggle (eg a show Password check box) use

对于像我这样想要在密码和*文本模式之间切换的其他人来说,这可能会有所帮助。我尝试使用建议的输入方法,但它只在一个方向上工作。我可以从密码到文本,但后来我无法恢复。对于那些试图处理切换(例如显示密码复选框)的人使用

       @Override
        public void onClick(View v)
        {
            if(check.isChecked())
            {
                edit.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
                Log.i(TAG, "Show password");
            }
            else
            {
                edit.setTransformationMethod(PasswordTransformationMethod.getInstance());
                Log.i(TAG, "Hide password");

I know the expected Answer is in Java . But here's my 2 cents of advice always try to handle view related stuff in XML (atleast basic stuff) so I would suggest rather use a xml attribute rather than handling this use case in java

我知道预期的答案是Java。但是这里我的2美分建议总是试图处理XML中的视图相关内容(至少基本的东西)所以我建议使用xml属性而不是在java中处理这个用例

    <EditText
     android:inputType="textPassword"/>

Try adding this to the EditText/TextView tag in your layout

尝试将其添加到布局中的EditText / TextView标记

android:password="true"

Edit: I just re-read your post, perhaps you need to do this after construction. I don't see why your snippet wouldn't work.

编辑:我刚刚重新阅读你的帖子,也许你需要在施工后这样做。我不明白为什么你的代码片不起作用。
