xrichtext's Introduction

XRichText

一个Android富文本类库,支持图文混排,支持编辑和预览,支持插入和删除图片。

实现的原理:

  • 使用ScrollView作为最外层布局,里面填充TextView和ImageView。
  • 删除的时候,根据光标的位置,删除TextView和ImageView。
  • 生成的数据为list集合,可自定义处理数据格式。

使用方式

  1. 作为类库 把xrichtext作为一个module导入你的工程。 把xrichtext中的文件拷贝到你的工程,可以在你的工程中建一个xrichtextming包名,并把文件拷贝进去。

  2. gradle依赖 稍后支持。

具体使用

在xml布局中添加基于EditText编辑器(可编辑)

<com.sendtion.xrichtext.RichTextEditor
    android:id="@+id/et_new_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textSize="@dimen/text_size_16"
    android:textColor="@color/grey_600"/>

在xml布局中添加基于TextView编辑器(不可编辑)

<com.sendtion.xrichtext.RichTextView
    android:id="@+id/tv_note_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textSize="@dimen/text_size_16"
    android:textColor="@color/grey_600"/>

我把数据保存为了html格式,生成字符串存储到了数据库。

生成数据

String noteContent = getEditData();

private String getEditData() {
    List<RichTextEditor.EditData> editList = et_new_content.buildEditData();
    StringBuffer content = new StringBuffer();
    for (RichTextEditor.EditData itemData : editList) {
        if (itemData.inputStr != null) {
            content.append(itemData.inputStr);
        } else if (itemData.imagePath != null) {
            content.append("<img src=\"").append(itemData.imagePath).append("\"/>");
        }
    }
    return content.toString();
}

显示数据

et_new_content.post(new Runnable() {
     @Override
     public void run() {
         showEditData(content);
     }
 });
        
protected void showEditData(String content) {
    et_new_content.clearAllLayout();
    List<String> textList = StringUtils.cutStringByImgTag(content);
    for (int i = 0; i < textList.size(); i++) {
        String text = textList.get(i);
        if (text.contains("<img")) {
            String imagePath = StringUtils.getImgSrc(text);
            int width = ScreenUtils.getScreenWidth(this);
            int height = ScreenUtils.getScreenHeight(this);
            et_new_content.measure(0,0);
            Bitmap bitmap = ImageUtils.getSmallBitmap(imagePath, width, height);
            if (bitmap != null){
                et_new_content.addImageViewAtIndex(et_new_content.getLastIndex(), bitmap, imagePath);
            } else {
            et_new_content.addEditTextAtIndex(et_new_content.getLastIndex(), text);
            }
            et_new_content.addEditTextAtIndex(et_new_content.getLastIndex(), text);
        }
    }
}

具体的使用方式,请参考Demo代码。
