1.0.1-1.0.4
- fix bug
-
1.0.0
- use more elegant implementation of @mention（special thanks to iYaoy）
- clearer package structure
- library for supporting Glide/AndroidGifDrawable
Usage
Gradle
- root build.gradle
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
- dependency
dependencies {
implementation 'com.github.sunhapper.SpEditTool:SpEditText:{last version}'
//help to create gif drawable use Glide
implementation 'com.github.sunhapper.SpEditTool:SpGlideDrawable:{last version}'
//help to create gif drawable use AndroidGifDrawable
implementation 'com.github.sunhapper.SpEditTool:SpGifDrawable:{last version}'
}
xml
EditText
- CustomInputConnectionWrapper to accept keyEvent，because setOnKeyListener may not react KeyEvent when use Google input method
- SpanChangedWatcher to handle @mention content
- GifWatcher to display gif on text
<com.sunhapper.x.spedit.view.SpXEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
TextView
<com.sunhapper.x.spedit.view.SpXTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
java
- create @mention Spannable
//IntegratedSpan will be fully removed
public class MentionUser implements IntegratedSpan {
public String name;
public long id;
public Spannable getSpannableString() {
SpannableString spannableString = new SpannableString(getDisplayText());
spannableString.setSpan(new ForegroundColorSpan(Color.MAGENTA), 0, spannableString.length(),
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
spannableString.setSpan(this, 0, spannableString.length(),
Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
SpannableStringBuilder stringBuilder = new SpannableStringBuilder();
return stringBuilder.append(spannableString).append(" ");
}
}
- delete style span when BreakableSpan was broken
//BreakableSpan can be part removed
public class Topic implements BreakableSpan {
...
/**
* @return true the BreakableSpan will be removed
* you can remove custom style span when content broken
*/
@Override
public boolean isBreak(Spannable text) {
int spanStart = text.getSpanStart(this);
int spanEnd = text.getSpanEnd(this);
boolean isBreak = spanStart >= 0 && spanEnd >= 0 && !text.subSequence(spanStart, spanEnd).toString().equals(
getDisplayText());
if (isBreak && styleSpan != null) {
text.removeSpan(styleSpan);
styleSpan = null;
}
return isBreak;
}
}
- load gif with AndroidGifDrawable
Drawable drawable = new TextGifDrawable(emojiconFile);
Spannable spannable = SpUtil.createGifDrawableSpan(gifDrawable,"text");
- load gif with Glide
//placeholder drawable
GifDrawable gifDrawable = new TextGifDrawable(getResources(), R.drawable.a);
ProxyDrawable proxyDrawable = new ProxyDrawable();
GlideApp.with(this)
.load(gifurl)
.placeholder(gifDrawable)
.into(new DrawableTarget(proxyDrawable));
return SpUtil.createResizeGifDrawableSpan(proxyDrawable, "text");
- custom Factory
- you can create your own SpanWatcher and Spannable.Factory/Editable.Factory
- use
setSpannableFactory/setEditableFactoryinstead of using SpXTextView or SpXEditText
proguard
-keep class com.sunhapper.x.spedit.**{*;}
