Android TextView Change the color of some text and replace the text in String.xml

One: The TextView component changes the color of some text:

Java code

2. TextView TextView = (TextView) Findviewbyid (R.id.textview);
6. Method One:
8. Textview.settext (html.fromhtml ("<font color=\" #ff0000 \ "> Red </font> Other Colors"));
12. Method Two:
14. String Text = "Get the Silver chest!";
16. Spannablestringbuilder style=New Spannablestringbuilder (text);
18. Style.setspan (new Backgroundcolorspan (color.red),2,5,spannable.span_exclusive_inclusive); //sets the background color of the specified position TextView
20. Style.setspan (new Foregroundcolorspan (color.red),0,2,spannable.span_exclusive_inclusive); //sets the color of the text at the specified position
22. Textview.settext (style);

Second: the integer and string types in the Android string.xml file are replaced by:

Java code

1. String Text = String.Format (Getresources (). getString (R.string.baoxiang), 2,"Silver Treasure Chest");

The corresponding string.xml file parameters:

XML code

1. <string name="Baoxiang"> You played the%1$d today, and the%2$D bureau can get%3$s! </string>

%1$d expression means the entire Name= "Baoxiang" string, the first integral type

In project developers, it is often necessary to combine the two. You can avoid many textview stitching, as shown below:

2. TextView TextView = (TextView) Findviewbyid (R.id.testview);
6. String Text = String.Format (Getresources (). getString (R.string.baoxiang), 2,"Silver Treasure Chest");
8. int index[] = new int[3];
10. index[0] = Text.indexof ("2");
12. index[1] = Text.indexof ("18");
14. index[2] = Text.indexof ("Silver treasure Chest");
18. Spannablestringbuilder style=New Spannablestringbuilder (text);
20. Style.setspan (new Foregroundcolorspan (color.red), index[0],index[0]+1,spannable.span_exclusive_      INCLUSIVE);
22. Style.setspan (new Foregroundcolorspan (color.red), index[1],index[1]+2,spannable.span_exclusive_      INCLUSIVE);
24. Style.setspan (new Backgroundcolorspan (color.red), index[2],index[2]+3,spannable.span_exclusive_      INCLUSIVE);
26. Textview.settext (style);
