By using this code I get results shown below, which is not what I want:

推荐答案

您需要使用 Spannable String:

You need to use a Spannable String:

TextView textView = (TextView)findViewById(R.id.textView1);
String  text = "Test"; 
Spannable spanText = Spannable.Factory.getInstance().newSpannable(text);
spanText.setSpan(new BackgroundColorSpan(0xFFFFFF00), 14, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(spanText);

试试这个.这会奏效.
