如何在Android中以编程方式禁用表情符号 [英] How to disable emojis programmatically in Android

问题描述

我想以编程方式隐藏键盘上的表情符号和自动建议.它可以在某些Android设备上运行，但不能在所有设备上运行.这是隐藏自动建议的代码:

I want to hide emojis and auto suggestions from keyboard programmatically. Its working in some Android devices but not in all devices. here's my code for hide auto suggestions:

txtSingupemail.setInputType(InputType.TYPE_TEXT_VARIATION_FILTER | InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS 
                           |InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
txtSignuppwd.setInputType(InputType.TYPE_TEXT_VARIATION_FILTER | InputType.TYPE_TEXT_VARIATION_PASSWORD);
txtSignuppwd.setTransformationMethod(PasswordTransformationMethod.getInstance());

以下是我的用户界面的快照:

这是用户单击登录"按钮时的布局.当用户点击标记为红色的左下图标时，由于表情符号的建议，键盘高度会增加.

This is layout when user clicks signIn button. When user tap on bottom left icon which is marked red, the keyboard height goes increase due to emojis as suggestions.

请参见以下快照:

推荐答案

尝试一下对我有用

editText.setFilters(new InputFilter[]{new EmojiExcludeFilter()});
private class EmojiExcludeFilter implements InputFilter {

        @Override
        public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
            for (int i = start; i < end; i++) {
                int type = Character.getType(source.charAt(i));
                if (type == Character.SURROGATE || type == Character.OTHER_SYMBOL) {
                    return "";
                }
            }
            return null;
        }
    }
