Hi,

are you using the new SDK?
If so change the following in your XML:

Using xml Syntax Highlighting

<TextView id="@+id/text"

to

Using xml Syntax Highlighting

<TextView android:id="@+id/text"
Parsed in 0.000 seconds,  using GeSHi 1.0.8.4

Also, those HTML syntaxes are only usable when you are making a reference to a String value in resources.

Using xml Syntax Highlighting

 
<resource>
 
    <string name="bold">This is a <b>bold</b>word</string>
 
</resources>

Hello rmeph,

1. You should upgrade to m5

2. To style text on the fly, you must make sure the TextView is using Spannable storage for the text (this will always be true if the TextView is an EditText), retrieve its text with getText(), and call setSpan(Object, int, int, int), passing in a new style class from the android.text.style package and the selection range.

The following code snippet demonstrates creating a string with a highlighted section, italic section, and bold section, and adding it to an EditText object.

Using java Syntax Highlighting

// Get our EditText object.
 
EditText vw = (EditText)findViewById(R.id.text);
 
// Set the EditText's text.
 
vw.setText("Italic, highlighted, bold.");
 
// If this were just a TextView, we could do:
 
// vw.setText("Italic, highlighted, bold.", TextView.BufferType.SPANNABLE);
 
// to force it to use Spannable storage so styles can be attached.
 
// Or we could specify that in the XML.
 
// Get the EditText's internal text storage
 
Spannable str = vw.getText();
 
// Create our span sections, and assign a format to each.
 
str.setSpan(new StyleSpan(android.graphics.Typeface.ITALIC), 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 
str.setSpan(new BackgroundColorSpan(0xFFFFFF00), 8, 19, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
 
str.setSpan(new StyleSpan(android.graphics.Typeface.BOLD), 21, str.length() - 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Hello rmeph,

you could create a small parcelable -Wrapper

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

        class MyPseudoArray implements Parcelable{
                private String[] strs;
                MyPseudoArray(String[] aStrArr){ this.strs = aStrArr;}
                @Override
                public void writeToParcel(Parcel pParcel) {
                  pParcel.writeStringArray(strs);
                }
        }
Parsed in 0.034 seconds,  using GeSHi 1.0.8.4

Then use it like this:

Using java Syntax Highlighting

Bundle b = new Bundle();
b.putParcelable("bla", new MyPseudoArray(new String[]{"A","B","C"}));
