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

2.  XML

3. fragement片段初始化

 private void initEditor(){
        mPreview = (TextView) mActivity.findViewById(R.id.preview);
        mEditor = (RichEditor) mActivity.findViewById(R.id.editor);
        //初始化编辑高度
        mEditor.setEditorHeight(200);
        //初始化字体大小
        mEditor.setEditorFontSize(16);
        //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);

        //mPreview = (TextView) mActivity.findViewById(R.id.preview);

        mEditor.setOnTextChangeListener(new RichEditor.OnTextChangeListener() {
            @Override
            public void onTextChange(String text) {
                mPreview.setText(text);
            }
        });

        mActivity.findViewById(R.id.action_undo).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mEditor.undo();
            }
        });

        mActivity.findViewById(R.id.action_redo).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mEditor.redo();
            }
        });

        mActivity.findViewById(R.id.action_heading1).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mEditor.setHeading(1);
            }
        });

        mActivity.findViewById(R.id.action_heading2).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mEditor.setHeading(2);
            }
        });

        mActivity.findViewById(R.id.action_heading3).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mEditor.setHeading(3);
            }
        });

        mActivity.findViewById(R.id.action_heading4).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mEditor.setHeading(4);
            }
        });

        mActivity.findViewById(R.id.action_heading5).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mEditor.setHeading(5);
            }
        });

        mActivity.findViewById(R.id.action_heading6).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mEditor.setHeading(6);
            }
        });
