PraiseTextView

说明

我是将朋友圈分成了几个独立模块单独自定义的View,通过回调完成交互,耦合性算是非常低了,主要有以下及部分:

示例

onClick (int position, PraiseTextView.PraiseInfo mPraiseInfo)

onOtherClick

布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/activity_main"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical"
 android:paddingBottom="@dimen/activity_vertical_margin"
 android:paddingLeft="@dimen/activity_horizontal_margin"
 android:paddingRight="@dimen/activity_horizontal_margin"
 android:paddingTop="@dimen/activity_vertical_margin"
 tools:context="com.lujianchao.praisetextview.MainActivity">
 <com.lujianchao.praisetextview.PraiseTextView
	android:layout_width="match_parent"
	android:id="@+id/praisetextview"
	android:layout_height="wrap_content"
	/>
 <TextView
	android:id="@+id/log"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:scrollbars="vertical"/>
</LinearLayout>
