Java代码包装html文本装入android TextView实现跑马灯

        String html = "<font color=\\"#436EEE\\">▰</font><font color=\\"#6495ED\\">▰</font><font color=\\"#CAE1FF\\">▰</font>";
        String ss = "";
        for (int i = 0; i < 100; i++) 
            ss = ss + html;
        

        TextView textView = findViewById(R.id.text);
        if (textView != null) 
            Spanned spanned = Html.fromHtml(ss, Html.FROM_HTML_MODE_COMPACT);
            textView.setText(spanned);
            textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
            textView.setSingleLine(true);
            textView.setSelected(true);
        

至于xml布局里面的TextView非常简单：

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textStyle="bold" />
