I use BackgroundColorSpan to show multiple highlights for a TextView. It shows correctly on Android API 23 and below, but has a problem with API 24 and 25.
final static String article1 = "Last year’s Google Pixel and Pixel XL were without question " +
"two of the hottest new smartphones of 2016. Google surprised fans by ditching its " +
"Nexus lineup of devices and moving from affordable upper mid-range devices to " +
"high-end flagship phones. Sure they were more expensive than Google phones had " +
"been in the past, but they were also a much better platform for showcasing the best " +
"of what Android has to offer, featuring high-end specs and a sleek metal and " +
"glass design.";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SpannableStringBuilder sb = new SpannableStringBuilder(article1);
BackgroundColorSpan span;
for (int i = 0; i < 3; i++) {
span = new BackgroundColorSpan(Color.YELLOW);
sb.setSpan(span, 23, 214, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
}
span = new BackgroundColorSpan(Color.RED);
sb.setSpan(span, 67, 83, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
span = new BackgroundColorSpan(Color.RED);
sb.setSpan(span, 216, 236, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
TextView tv = (TextView) findViewById(R.id.body);
tv.setText(sb);
}
}
If loop 3, only one red highlight will show. If loop 2, both red highlights will show.
