问题 I'm trying to implement Emoji's in my app and I should use short codes (like :dog: , :cat: ), not unicode. I have two devices to test on and two different behaviours of EditText and ImageSpan in it. First: Meizu PRO 6, Android 6.0 (API 23) Everything works as I want. When you tap backspace on the spanned text, it disappears from EditText completely, because full spanned part of the string was removed. For example, you have a "Hello :dog: " in your EditText ( :dog: is replaced with a picture

问题 I'm working on an app that reads in text from an XML document and then displays that text on the screen. I want to be able to create a TextAppearanceSpan object programmatically based on parameters given in the XML document (font, size, color, bold/italic, etc.) that don't rely on Resource files (for SpannableString s in my TextView). I was looking at the following constructor: TextAppearanceSpan(String family, int style, int size, ColorStateList color, ColorStateList linkColor) but I can't

问题 I seem to be getting what seems like some extra line breaks after using this method to set the text of a TextView message.setText(Html.fromHtml( message )); How can I remove these? They cause my layout to get warped since it adds two extra lines to the output. The string was saved to my sqlite database via Html.toHtml( editText.getText() ).trim(); Initial string input : hello Log output of the message variable: <p dir="ltr">hello</p> 回答1: Looks like toHtml assumes everything should be in a <p

问题 I'm trying to solve a problem I'm having with Cardslib and spannable text. Cards display correctly and each card shows the text I made spannable. Each spanned text has an overriden onClick listener that replaces current fragment. The problem seems to be that Cardslib is catching the onClick event and it isn't propagated to the handlers inside the spannable text. Does that make sense? Thanks in advance! 来源： https://stackoverflow.com/questions/27007531/android-cardslib-how-to-propagate-card

问题 I've a MultiAutoCompleteTextView custom control in which I am creating chips text, when user presses the space key. I do not want the user to input space initially when the textbox is empty so I put an inputFilter in order to prevent user from putting space initially. Here's the Filter Code: private void RestrictUselessSpaces(){ InputFilter filter = new InputFilter() { public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) { for (int i = start;

问题 I have a ListView where I managed to display many texts on it. Some of the texts are formatted as BOLD . In order to make those texts bold, I used Spannable and it works! However, when I scrolled it down and up again, the index[0] goes multiple. To avoid that scene, I used a holder to hold my TextViews. I managed to solve that problem in scrolling but for some reasons, the textstyle which is BOLD, gone in my ListView. How can I do that? MainActivity.java private void populateListView() {
