android TextView 实现自定义文字点击效果

Android TextView 可以通过

android:autoLink="phone" 来设置文字的默认点击行为。我们也可以自己定义文字的点击行为

TextView textView = (TextView) findViewById(R.id.span_text);StringBuilder sb = new StringBuilder();sb.append("个人信息");sb.append("+ ">"        + "地址");sb.append("+ ">"        + "名字");textView.setText(Html.fromHtml(sb.toString()));textView.setMovementMethod(LinkMovementMethod.getInstance());textView.setHighlightColor(Color.TRANSPARENT);//去掉点击后的蓝色背景CharSequence text = textView.getText();if (text instanceof Spannable) {    int end = text.length();    Spannable sp = (Spannable) textView.getText();    URLSpan[] urls = sp.getSpans(0, end, URLSpan.class);    SpannableStringBuilder style = new SpannableStringBuilder(text);    style.clearSpans();// should clear old spans    // 循环把链接发过去    for (URLSpan url : urls) {        MyURLSpan myURLSpan = new MyURLSpan(url.getURL());        style.setSpan(myURLSpan, sp.getSpanStart(url),                sp.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);    }    textView.setText(style);}

class MyURLSpan extends ClickableSpan{    String url;    @Override    public void updateDrawState(TextPaint ds) {        super.updateDrawState(ds);        ds.setColor(Color.parseColor("#f37021"));//颜色        ds.setUnderlineText(false);//去掉下划线    }    public MyURLSpan(String url) {        this.url = url;    }    @Override    public void onClick(View widget) {        Toast.makeText(MainActivity.this, url + " is clicked" ,Toast.LENGTH_SHORT).show();    }}
