spannable

I have this to identify wich characters will be subsituted by an Image throught an ImageSpan (this is called only when an smileys character is inserted on EditText): for (index = start; index < start+num_chars; index++) { if (index + 1 > editable.length()) continue; if(emoticons.containsKey(editable.subSequence(index, index + 1).toString())){ int length=1; Drawable drawable = context.getResources().getDrawable(emoticons.get(editable.subSequence(index, index + 1).toString())); Bitmap bitmap =

Suppose you have the following string: String s = "The cold hand reaches for the %1$s %2$s Ellesse's"; String old = "old"; String tan = "tan"; String formatted = String.format(s,old,tan); //"The cold hand reaches for the old tan Ellesse's" Suppose you want to end up with this string, but also have a particular Span set for any word replaced by String.format .

I have used this StyleSpanRemover to remove style from selected text, but i have a problem. I want to have a bold button that toggle bold style of selected text. it means if the selected text (or part of that) is not bold, bold all of them; and if all of selected text is bold, remove bold style from it. But when i use this code, after one removing bold style on a text and again bolding it, getStyle() always returns Typeface.NORMAL Here is the code i have used: boolean isAllSpansBold = true; /** * Bold selected text */ Spannable spannable = new SpannableString(mEditTextContent.getText());

I am trying to display some text in an alert dialog box as a hyperlink. Part of the process requires me to use SpannableString to format some text. The problem is that my application experiences a runtime error on the SpannableString part of my code. TextView Tv= (TextView) findViewById(R.id.textView3); SpannableString s = new SpannableString("www.google.com"); Linkify.addLinks(s, Linkify.WEB_URLS); Tv.setText(s); Tv.setMovementMethod(LinkMovementMethod.getInstance()); I looked in the DDMS and the Error says Java.Lang.NullPointerException. Has anyone experienced this? I Should be able to pass

I wanted to create a empty bullet paragraph, but it didn't work. This is my code: EditText contentET = (EditText) findViewById(R.id.content); contentET.setText("abc\n123\n"); Spannable s = contentET.getText(); s.setSpan(new BulletSpan(), 0, 1, Spannable.SPAN_INCLUSIVE_INCLUSIVE); s.setSpan(new BulletSpan(), 4, 5, Spannable.SPAN_INCLUSIVE_INCLUSIVE); s.setSpan(new BulletSpan(), 7, 8, Spannable.SPAN_INCLUSIVE_INCLUSIVE); contentET.setText(s); When i ran above code, it seemed this line doesn't work s.setSpan(new BulletSpan(), 7, 8, Spannable.SPAN_INCLUSIVE_INCLUSIVE); Instead, i saw an unexpected

Here is what it looks like in the beginning when I haven't added any imagespan chips - As you can tell there the cursor is placed at the right size and the gravity is respected. Then when I add an imagespan, the cursor all of a sudden becomes bigger like this - I don't understand why this happens and I also don't know how to fix it, i.e. keep the cursor the same size. Finally when I start typing again, the cursor is all wierd while maintaining the size of the of the font and the span also moves a little to the bottom. I really want to the keep the cursor the same size and keep it centered I'm
