spannable

问题 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

If there is bold typeface elsewhere in the EditText , and I try to create a new bold section, the original section is changed back to normal . For example, this string: Bold not bold more bold. If I highlight any of the normal words and press the button, they do become bold , but the first word becomes normal . I can't see any

问题 Background I'm trying to use a simple SpannableString on a TextView , based on an UnderDotSpan class I've found (here). The original UnderDotSpan just puts a dot of a specific size and color below the text itself (not overlapping). What I'm trying is to first use it normally, and then use a customized drawable instead of a dot. The problem As opposed to a normal span usage, this one just doesn't show anything. Not even the text. Here's how it's done for a normal span: val text = "1" val

问题 I want to set style to selected text from EditText using custom typeface . I am getting below error at compile time. The constructor StyleSpan(Typeface) is undefined . Below code I am applying. int start=editbox.getSelectionStart(); int end=editbox.getSelectionEnd(); Spannable span=(Spannable)editbox.getText(); StyleSpan f = new StyleSpan( Typeface.createFromAsset(getAssets(), "fonts/genbkbasr.ttf")); span.setSpan(f, start,end, 0); Thanks. 回答1: I wrote a class to work around this limitation.

问题 i have a TextView filled with text which i get from a server. I'm using Linkify for handling all the link searching and for setting a URLSpan where needed throughout its addLinks method. The problem is that the default behavior when clicking a link is opening it in a browser, what i want is to get the clicked link and handle it my self. I don't see any method of Linkify which let me set a "OnClick" or something... Thank for your help :) 回答1: Ok so i finally managed to set my own

问题 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

问题 Basically what I want to create can be best illustrated from a screenshot. I have a listview of people just like FB Messenger app. I want the ability for my users to have a search bar like the one shown in the screenshots. It should have the following properties: 1) Search bar should preview names of people selected in the list view 2) People can be de-selected by hitting backspace on any name in the preview search bar 3) The search bar should be able to filter the bottom list of people as

问题 Background The support library (docs here) allows you to use TTF fonts files in the "res/font" folder, either in XML : app:fontFamily="@font/lato_black" or via code: val typeface = ResourcesCompat.getFont(context, R.font.lato_black) The problem While I know it's possible to use spannable technique to set different styles in parts of the TextView content (such as bold, italic, colors,etc...) , the only thing I've found for setting a different font, is by using the built in fonts of the OS, as
