Android Development: How To Replace Part of an EditText with a Spannable

由 旧城冷巷雨未停 提交于 2019-11-27 06:13:10
问题 I'm trying to replace part of an Editable returned from getText() with a span. I've tried getText().replace() but that's only for CharSequences . The reason I'm trying to do this is so I can highlight sections of an EditText one after another (after a small delay), instead of going through and highlighting the whole EditText (which can be slow with big files). Does anyone have a clue about how I'd go about doing this? 回答1: This minimal size example makes the word 'first' large: public class

问题 I am trying to construct a SpannableString such that it looks like this: Two characters (m, s) should be smaller than the rest. I have tried to hold all the text in one SpannableString, and I also tried to concatenate two SpannableStrings via a SpannableStringBuilder. The code for one Spannable looks like this: spannable.setSpan(new RelativeSizeSpan(0.75f), spannable.length() - 1, spannable.length(), 0); However, only one formatting is applied - when using the SpannableStringBuilder, only the

Align text around ImageSpan center vertical

I have an ImageSpan inside of a piece of text. What I've noticed is that the surrounding text is always drawn at the bottom of the text line -- to be more precise, the size of the text line grows with the image but the baseline of the text does not shift upward. When the image is noticeably larger than the text size, the effect is rather unsightly. Here is a sample, the outline shows bounds of the TextView : I am trying to have the surrounding text be centered vertically with respect to the image being displayed. Here is the same sample with blue text showing the desired location: Here are the

Is this possible to set different textSize in one TextView? I know that I can change text style using: TextView textView = (TextView) findViewById(R.id.textView); Spannable span = new SpannableString(textView.getText()); span.setSpan(arg0, 1, 10, arg3); textView.setText(span) I know the range start...end of text I want to change size. But what can I use as arg0 and arg3 ?
