我想startActivity(new Intent(context, MyProfile.class));在用户使用 # 或 @ 在 textview 上 clike 时打开新的活动
这是我的代码
class CalloutLinkProfile extends ClickableSpan {
Context context;
TextPaint textPaint;
public CalloutLinkProfile(Context ctx) {
super();
context = ctx;
}
@Override
public void updateDrawState(TextPaint ds) {
textPaint = ds;
// ds.setColor(0xff336699);
ds.setARGB(255, 30, 144, 255);
ds.setTypeface(Typeface.DEFAULT_BOLD);
ds.setUnderlineText(false); // set to false to remove underline
}
@Override
public void onClick(View widget) {
TextView tv = (TextView) widget;
Spanned s = (Spanned) tv.getText();
int start = s.getSpanStart(this);
int end = s.getSpanEnd(this);
String theWord = s.subSequence(start + 1, end).toString();
Toast.makeText(context, String.format("Here's a cool user: %s", theWord), 10).show();
startActivity(new Intent(context, MyProfile.class));
}
这是我的完整代码
