如何复制 android:editable="false";在代码中? [英] How to replicate android:editable="false" in code?

问题描述

在布局中，您可以通过 android:editable 属性将 EditText 小部件设置为不可编辑.

In the layout you can set the EditText widget to be non-editable via the android:editable attribute.

如何在代码中做到这一点?我需要根据条件使 EditText 小部件可编辑.

How can I do this in code? I need to make the EditText widget to be editable depending on conditions.

推荐答案

我想一个 InputFilter 拒绝所有更改是一个很好的解决方案:

I think an InputFilter that rejects all changes is a good solution:

editText.setFilters(new InputFilter[] {
    new InputFilter() {
        public CharSequence filter(CharSequence src, int start,
            int end, Spanned dst, int dstart, int dend) {
            return src.length() < 1 ? dst.subSequence(dstart, dend) : "";
        }
    }
});

dlazar 建议(如下)将 return 更改为 dst.subSequence(dstart,dend) 以克服删除单词的行为.

dlazar suggested (below) to change the return to dst.subSequence(dstart, dend) to overcome behavior that removes words.
