How to get a red asterisk in a entry

Question

How do you get a red asterisk in a entry so that you can display it at the end of the text to indicate its a required field, like: Enter your name * (asterisk will be red).

Answer 1

Initialize variable in strings.xml <string name="date_of_incident">Date of Incident <p><font color="red">*</font></p></string>

Answer 2

Refer to this for examples on how to style portions of a textview. Here's how you could do it for a red asterisk.

EditText editTxt = new EditText(this);
editTxt.setText("Testing asterisk *");
Spannable str = editTxt.getTxt();
int loc = editTxt.getTxt().toString().indexOf("*");
str.setSpan(new ForegroundColorSpan(Color.RED), loc, 1, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

Answer 3

Alternative for showing asterisk in android Textview

txtvw2.setText(Html.fromHtml("<sup>*</sup>"+"enter you name"));

Answer 4

You can't do that through xml string resources. This can only be done via code. For this you need to use SpannableStringBuilder and ForegroundColorSpan.

Here is small example:

TextView text = (TextView)findViewById(R.id.text);

String simple = "Enter your name ";
String colored = "*";
SpannableStringBuilder builder = new SpannableStringBuilder();

builder.append(simple);
int start = builder.length();
builder.append(colored);
int end = builder.length();

builder.setSpan(new ForegroundColorSpan(Color.RED), start, end, 
                Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

text.setText(builder);
