本文整理了Java中android.os.Parcel.dataAvail()方法的一些代码示例，展示了Parcel.dataAvail()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Parcel.dataAvail()方法的具体详情如下：
包路径：android.os.Parcel
类名称：Parcel
方法名：dataAvail

Parcel.dataAvail介绍

[英]Returns the amount of data remaining to be read from the parcel. That is, #dataSize- #dataPosition.
[中]返回要从地块读取的剩余数据量。也就是说，#数据大小-#数据位置。

 // Create a parcel2 that sandwiches parcel1 with happy birthday.
 Parcel parcel2 = Parcel.obtain();
