最佳回答

http:// developinger.android.com/ reference/and/android/widget/TextView.html" rel=“nofollow” >TextView 元素,或TextView(例如编辑图文)的任何子分类,您可以用seetFilter()()。

您需要做的是创建一个执行 输入过滤器的类, 例如

public class MyTestFilter implements InputFilter {

    @Override
    public CharSequence filter(CharSequence source, int start, int end,
            Spanned dest, int dstart, int dend) {
        // do you checks, and only return what you wish to have replaced
        return null;
    }
}

并然后使用

youEditText.setFilters(new InputFilter[]{new MyTestFilter()});
