android string layout encoding url class
运行结果如下：
TtActivity.java
public class TtActivity extends Activity {
/* * Called when the activity is first created. */private TextView tv;
static Context ctx = null ;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ctx = this ;
tv = (TextView) findViewById(R.id.tv);
// String htmlLinkText= " 我的CSDN博客 ";
// tv.setText(Html.fromHtml(htmlLinkText));
tv.setMovementMethod(LinkMovementMethod.getInstance());
CharSequence text = tv.getText();
if (text instanceof Spannable){
int end = text.length();
Spannable sp = (Spannable)tv.getText();
URLSpan[] urls = sp.getSpans( 0 , end, URLSpan. class );
SpannableStringBuilder style = new SpannableStringBuilder(text);
style.clearSpans(); // should clear old spans
for (URLSpan url : urls){
MyURLSpan myURLSpan = new MyURLSpan(url.getURL());
style.setSpan(myURLSpan,sp.getSpanStart(url),sp.getSpanEnd(url),Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
}
tv.setText(style);
}
}
private static class MyURLSpan extends ClickableSpan{
private String mUrl;
MyURLSpan(String url) {
mUrl = url;
}
@Override
public void onClick(View widget) {
// TODO Auto-generated method stub
Toast.makeText(ctx, ""+mUrl ,Toast.LENGTH_SHORT).show();
}
}
}
main.xml
