1.现在有一个需求，textview中的字符串，例如：”你好，欢迎来到android世界！http://www.google.com 谷歌是我们的一个好工具“ 点击字符串中的网址不让其跳转到浏览器中，而是能够解析网址中的id，从而跳转到app中特定的activity中。我已经设置了textview的属性autolink="true"
2.目前的问题是，点击网址总是跳转到浏览器！所以我该如何捕捉到点击网址的事件或者如何跳转到指定的Activity中？
我之前这么写过，你看有没有帮助
public class MainActivity extends ActionBarActivity {
private TextView textView;
static Context ctx = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.tv);
ctx = this;
textView = (TextView) findViewById(R.id.tv);
String htmlLinkText = "<a href=\"" + "http:" + "/" + "/"
+ "www.baidu.com\"><u>我的CSDN博客 </u></a>";
textView.setText(Html.fromHtml(htmlLinkText));
textView.setMovementMethod(LinkMovementMethod.getInstance());
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();
for (URLSpan url : urls) {
MyURLSpan myURLSpan = new MyURLSpan(url.getURL());
style.setSpan(myURLSpan, sp.getSpanStart(url),
sp.getSpanEnd(url), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
textView.setText(style);
}
}
private static class MyURLSpan extends ClickableSpan {
private String mUrl;
MyURLSpan(String url) {
mUrl = url;
}
@Override
public void onClick(View widget) {
Toast.makeText(ctx, mUrl, Toast.LENGTH_SHORT).show();
}
}
}群主找到解决办法了吗？我也遇到了这样的问题
private void initAgreement(TextView text) {
text.setClickable(true);
text.setText(getClickableSpan(text));
text.setMovementMethod(LinkMovementMethod.getInstance());
}
private SpannableString getClickableSpan(TextView textView) {
View.OnClickListener listener1 = new View.OnClickListener() {
// 如下定义自己的动作
public void onClick(View v) {
Intent intent = new Intent(AboutActivity.this, ProtocalActivity.class);
intent.putExtra(ProtocalActivity.TITLE_KEY, getString(R.string.user_agreement_content_href1));
intent.putExtra(ProtocalActivity.CONTENT_URI_KEY, ProtocalActivity.END_USER_LICENSE_AGREEMENT);
startActivity(intent);
}
};
String agreement = textView.getText().toString();
String h1 = getResources().getString(R.string.user_agreement_content_href1);
int h1Index = agreement.indexOf(h1);
SpannableString spanableInfo = new SpannableString(agreement);
int start1 = h1Index;
if (start1 != -1) {
int end1 = start1 + h1.length();
spanableInfo.setSpan(new Clickable(listener1), start1, end1, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
spanableInfo.setSpan(new ForegroundColorSpan(Color.parseColor("#28c0c6")), start1, end1,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
return spanableInfo;
}
class Clickable extends ClickableSpan implements OnClickListener {
private final View.OnClickListener mListener;
public Clickable(View.OnClickListener l) {
mListener = l;
}
@Override
public void onClick(View v) {
mListener.onClick(v);
}
@Override
public void updateDrawState(TextPaint ds) {
ds.setUnderlineText(false);
}
}感谢各位热情网友的回答，我已经找到相关的答案了。具体如下：
-
注意android:autoLink="web"
<TextView android:id="@+id/text_view" android:layout_width="fill_parent" android:layout_height="wrap_content" android:autoLink="web" android:text="@string/hello" />2.重写url的点击事件
public class MainActivity extends Activity {
TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView) findViewById(R.id.tv);
CharSequence text = tv.getText();
if (text instanceof Spannable) {
int end = text.length();
Spannable sp = (Spannable) text;
URLSpan urls[] = sp.getSpans(0, end, URLSpan.class);
SpannableStringBuilder style = new SpannableStringBuilder(text);
style.clearSpans();
for (URLSpan urlSpan : urls) {
MyURLSpan myURLSpan = new MyURLSpan(urlSpan.getURL());
style.setSpan(myURLSpan, sp.getSpanStart(urlSpan),
sp.getSpanEnd(urlSpan),
Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
}
tv.setText(style);
}
}
private class MyURLSpan extends ClickableSpan {
private String url;
public MyURLSpan(String url) {
this.url = url;
}
@Override
public void onClick(View arg0) {
startActivity(new Intent(WXEntryActivity.this,RegisterActivity.class));
}
}
} 3.上面两步完美的解决了网站链接标高亮显示并且有下划线，点击时，可以在跳转到确定的Activity中
最后再次感谢各位的回答，更加感谢网友@小谷xg 评论中给出这方面的博客参考，学习到了很多很多。
不要用autolink属性， 直接设置textview的点击事件， 含符合条件的String 就除非相应的事件：比如调用某个activity
继承ClickableSpan重写onClick方法
需求描述：
1、楼主需要对网站链接标有下划线
2、楼主希望点击时，跳转到确定的Activity中
需要这么绕弯吗？直接textView设置clickable="true",然后设置textview.setOnclickListener点击事件，跳转就可以,textview.getText获得网址
