    private class TextViewURLSpan extends ClickableSpan {

		public TextViewURLSpan(String clickString) {
			this.clickString = clickString;
		}

		@Override
		public void updateDrawState(TextPaint ds) {
		    ds.setColor(MainActivity.this.getResources().getColor(R.color.text_color));
		    ds.setUnderlineText(false); //去掉下划线
		}
		
		@Override
		public void onClick(View widget) {
			if (clickString.equals("username")) {
				Toast.makeText(getApplication(), clickString, Toast.LENGTH_LONG)
				.show();
			} else if (clickString.equals("singstar")) {
				Toast.makeText(getApplication(), clickString, Toast.LENGTH_LONG)
						.show();
			}
		}
	}

}
