TextView 换行，左边是其它控件这个是之前的，没有进行封装，这次我想将其进行一个封装

效果图.png

可以定义的参数

设置左边view的drawable
app:tv_leo_left_background  

设置左边view的宽高
app:tv_leo_left_width
app:tv_leo_left_height

设置左边view的上下左右padding
app:tv_leo_left_paddingleft  
app:tv_leo_left_paddingright
app:tv_leo_left_paddingtop
app:tv_leo_left_paddingbottom

设置左边view的距离顶部的距离
app:tv_leo_left_margintop

设置左边view的文本颜色
app:tv_leo_left_textcolor

设置左边view的文本大小
app:tv_leo_left_textsize

设置右边view的最多行数
app:tv_leo_right_maxlines

设置右边view的文字颜色
app:tv_leo_right_textcolor

设置右边view的文本大小
app:tv_leo_right_textsize


  <com.gxx.textlayoutapplication.weiget.TextViewLeftOtherLayout
        android:id="@+id/tv_other_textview_left_other_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tv_leo_left_background="@drawable/shape_rectangle_solid_red_d0372a_corner50"
        app:tv_leo_left_paddingleft="8dp"
        app:tv_leo_left_paddingright="8dp"
        app:tv_leo_left_paddingtop="0dp"
        app:tv_leo_left_paddingbottom="0dp"
        app:tv_leo_left_textcolor="@color/green_48D2C5"
        app:tv_leo_left_textsize="14"
        app:tv_leo_right_maxlines="2"
        app:tv_leo_right_textcolor="@color/purple_200"
        app:tv_leo_right_textsize="18" />

  使用方式
  val textViewLeftOtherLayout = findViewById<TextViewLeftOtherLayout>(R.id.tv_other_textview_left_other_layout);
  textViewLeftOtherLayout.setLeftRightTextValue("来来来","在自定义View中通过Canvas绘制文字时，经常需要测量文字的宽度和高度的宽度和高度的宽度和高度");
