更改字符串中所选单词的颜色

Question

我试图以最基本的方式在android studio中编写问题和答案。我的计划是将答案设为白色（当前背景的颜色）......然后当按下答案按钮时，它会将整个事物改为黑色。那么你如何让答案跨越不同的颜色呢？

    Button button = (Button) findViewById(R.id.questionButton);

    button.setOnClickListener(
            new Button.OnClickListener() {
                public void onClick(View v) {
                    final String[] Text = {
                            "Q: Who is the first president of the United States? <COLOR SOMETHING TO MAKE THIS WHITE TEXT-> >A: George Washington</COLOR>"

                    };

Answer 1

您可以使用Spannable来实现此目标。

String text = "Q: Who is the first president of the United States? <font color='white'>A: George Washington</font>";
textView.setText(Html.fromHtml(text), TextView.BufferType.SPANNABLE);
