如何以编程方式在 Android TextView 中设置 maxLength? [英] How to programmatically set maxLength in Android TextView?

问题描述

我想以编程方式设置 TextView 的 maxLength 属性，因为我不想在布局中对其进行硬编码.我看不到任何与 maxLength 相关的 set 方法.

I would like to programmatically set maxLength property of TextView as I don't want to hard code it in the layout. I can't see any set method related to maxLength.

谁能指导我如何做到这一点?

Can anyone guide me how to achieve this?

推荐答案

应该是这样的.但从未将其用于文本视图，仅用于编辑文本:

Should be something like that. but never used it for textview, only edittext :

TextView tv = new TextView(this);
int maxLength = 10;
InputFilter[] fArray = new InputFilter[1];
fArray[0] = new InputFilter.LengthFilter(maxLength);
tv.setFilters(fArray);
