保持android按钮选择状态 [英] keep android button selected state

问题描述

我知道这是一个以前被问过很多次的问题，但我似乎无法在我的代码中解决它.我有两个按钮，当按下一个按钮时，我希望将其保持在选中状态，反之亦然.我试过使用 setSelected 和 setPressed 来做它，但我似乎无法让它工作.这是我正在使用的代码:

I know this is a question that has been asked many times before, but I can't seem to solve it in my code. I have two buttons, and when one is pressed, I would like to keep it in its selected state, and vice versa. I have tried doing it using but the setSelected and setPressed, but I can't seem to get it to work. Here is the code I am using:

    region_button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            objects = category;
            adap.notifyDataSetChanged();
            proximity_button.setPressed(false);
            region_button.setPressed(true);

        }
    });

    proximity_button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            objects = proximity;
            adap.notifyDataSetChanged();
            region_button.setPressed(false);
            proximity_button.setPressed(true);

        }
    });

根据评论，我需要补充一点，我有一个自定义的按钮 xml 背景，并希望保留当前的外观.

Based on the comments, I need to add that I have a custom xml background for the buttons, and would like to retain the current look.

推荐答案

我在 Google 上搜索并找到了这篇 Stack Overflow 帖子:
如何让一个按钮保持按下状态点击后?

I searched on Google and found this Stack Overflow post:
How can i keep one button as pressed after click on it?

mycodes_Button.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        mycodes_Button.setPressed(true);
        return true;
    }
});

但是看了评论，很有趣！
