    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
  • usesetSpannableFactory/setEditableFactoryinstead of using SpXTextView or SpXEditText

proguard

-keep class com.sunhapper.x.spedit.**{*;}
