Android EditText 最大长度

Android EditText Max Length(Android EditText 最大长度)

问题描述

我在 EditText 字段中设置了最大文本长度.

I set up a max length of text in an EditText field.

<EditText
            android:id="@+id/courseDescriptionField"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:inputType="textMultiLine"
            android:lines="5"
            android:maxLength="@integer/max_course_description_limit"
            android:gravity="left|top" >
        </EditText>

然而，对我来说问题是，文本在 140 个字符之后出现，但它仍然继续输入，除了文本没有出现，但是，它确实出现在缓冲区"中(意思是建议事情)如果这就是你所说的.

The problem for me however is, that, text STOPS appearing after 140 characters, but it still continues to type, except that text just doesn't appear, but however, it does appear in the "buffer" (meaning the suggestion thing) if that's what you would call it.

附带说明，我正在使用 TextWatcher 来跟踪限制.有没有办法完全限制文本的数量，这样当有 140 个字符时，按下退格/删除以外的东西时什么都不会发生?

As a side note, I am using a TextWatcher to keep track of the limit. Is there any way to completely limit the amount of text, so that when there are 140 characters, nothing happens when something other than backspace/delete is pressed?

推荐答案

限制Android中EditText的文本长度

使用 android:maxLength="140"

应该可以.:)
