Android textview changes the color of some text and replaces the text in string. xml.

The International UI is adjusted in the project, because the Chinese and English are different, so the knowledge here is used:

Java code

1. Textview = (textview) findviewbyid (R. Id. textview );
3. // Method 1:
4. Textview. settext (html. fromhtml ("<font color = \" # ff0000 \ "> Red </font> other colors "));
6. // Method 2:
7. String text = "get silver treasure box! ";
8. Spannablestringbuilder style = new spannablestringbuilder (text );
9. Style. setspan (New backgroundcolorspan (color. Red), spannable. span_exclusive_wide SIVE); // you can specify the background color of the textview.
10. Style. setspan (New foregroundcolorspan (color. Red), spannable. span_exclusive_wide SIVE); // you can specify the color of the text at the specified position.
11. Textview. settext (style );

 

 

 

 

Ii. Replacement of integer and string types in the android string. xml file:

 

Java code

1. String text = string. Format (getresources (). getstring (R. String. baoxiang), "silver chest ");

 

Corresponding string. xml file parameters:

 

XML Code

1. <String name = "baoxiang"> you played the % 1 $ D game today. % 2 $ D game! % 3 $ s! </String>

% 1 $ D indicates the first integer in the entire name = "baoxiang" string.

 

 

Project developers often need to combine the above two. You can avoid splicing many textviews, as shown below:

 

Java code

1. Textview = (textview) findviewbyid (R. Id. testview );
3. String text = string. Format (getresources (). getstring (R. String. baoxiang), "silver chest ");
4. Int index [] = new int [3];
5. Index [0] = text. indexof ("2 ");
6. Index [1] = text. indexof ("18 ");
7. Index [2] = text. indexof ("silver chest ");
9. Spannablestringbuilder style = new spannablestringbuilder (text );
10. Style. setspan (New foregroundcolorspan (color. Red), index [0], index [0] + 1, spannable. span_exclusive_inclusive );
11. Style. setspan (New foregroundcolorspan (color. Red), index [1], index [1] + 2, spannable. span_exclusive_inclusive );
12. Style. setspan (New backgroundcolorspan (color. Red), index [2], index [2] + 3, spannable. span_exclusive_inclusive );
13. Textview. settext (style );
