android项目实战之编辑器集成

引言

项目需要用到编辑器，采用RichEditor，如下效果

实现

1. 引入库2

   implementation 'jp.wasabeef:richeditor-android:2.0.0'

2. XML

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:layout_marginBottom="@dimen/dp_60" android:theme="@style/customTheme" >
   <HorizontalScrollView android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/app_color_9b">

        <LinearLayout

   private void initEditor(){

   //初始化编辑高度

   //初始化字体颜色
   mEditor.setEditorFontColor(Color.BLACK);
   //初始化内边距
   mEditor.setPadding(10, 10, 10, 10);
   //设置默认显示语句
   mEditor.setPlaceholder("请输入...");
   //设置编辑器是否可用
   mEditor.setInputEnabled(true);
