1、给文字添加局部变色及点击事件

private SpannableStringBuilder style;
private ClickableSpan clickableSpan;
@Override
protected void onCreate(@Nullable @org.jetbrains.annotations.Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // 给点击此处切换身份文字变色及添加点击事件
    style = new SpannableStringBuilder();
    //设置文字
    style.append("给点击此处切换身份文字变色及添加点击事件");
    //设置部分文字点击事件
    clickableSpan = new ClickableSpan() {
        @Override
        public void onClick(View widget) {
           startActivity(new Intent(ApproveLegalActivity.this, ApproveTypeActivity.class));
           finish();
        }

        @Override
        public void updateDrawState(@NonNull TextPaint ds) {
            super.updateDrawState(ds);
            // 去除下划线
            ds.setUnderlineText(false);
        }
    };
    style.setSpan(clickableSpan, 16, 20,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    hintMessage.setText(style);
    //设置部分文字颜色
    ForegroundColorSpan foregroundColorSpan = new ForegroundColorSpan(Color.parseColor("#0B8EFF"));
    style.setSpan(foregroundColorSpan, 16, 20, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    //配置给TextView
    hintMessage.setMovementMethod(LinkMovementMethod.getInstance());
    hintMessage.setText(style);
}

2、解决内存泄漏问题

@Override
protected void onDestroy() {
    super.onDestroy();
    if (clickableSpan != null){
        style.removeSpan(clickableSpan);
        style = null;
        hintMessage.setText(null);
    }
}
