本文整理了Java中android.os.Parcel.writeValue()方法的一些代码示例，展示了Parcel.writeValue()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.writeValue()方法的具体详情如下：
包路径：android.os.Parcel
类名称：Parcel
方法名：writeValue

Parcel.writeValue介绍

[英]Flatten a generic object in to a parcel. The given Object value may currently be one of the following types:

  • null
  • String
  • Byte
  • Short
  • Integer
  • Long
  • Float
  • Double
  • Boolean
  • String[]
  • boolean[]
  • byte[]
  • int[]
  • long[]
  • Object[] (supporting objects of the same type defined here).
  • Bundle
  • Map (as supported by #writeMap).
  • Any object that implements the Parcelable protocol.
  • Parcelable[]
  • CharSequence (as supported by TextUtils#writeToParcel).
  • List (as supported by #writeList).
  • SparseArray (as supported by #writeSparseArray(SparseArray)).
  • IBinder
  • Any object that implements Serializable (but see #writeSerializable for caveats). Note that all of the previous types have relatively efficient implementations for writing to a Parcel; having to rely on the generic serialization approach is much less efficient and should be avoided whenever possible.

Parcelable objects are written with Parcelable#writeToParcel using contextual flags of 0. When serializing objects containing ParcelFileDescriptors, this may result in file descriptor leaks when they are returned from Binder calls (where Parcelable#PARCELABLE_WRITE_RETURN_VALUE should be used).
[中]将常规对象展平到地块中。给定的对象值当前可能是以下类型之一：
*空的
*串
*字节
*短的
*整数
*长的
*漂浮
*加倍
*布尔值
*字符串[]
*布尔[]
*字节[]
*int[]
*长[]
*对象[]（支持此处定义的相同类型的对象）。
*捆
*映射（由#writeMap支持）。
*实现可包裹协议的任何对象。
*可包裹的
*CharSequence（由TextUtils#writeToParcel支持）。
*列表（由#writeList支持）。
*SparseArray（由#writeSparseArray（SparseArray））支持）。
*伊宾德
*任何实现Serializable的对象（但有关注意事项，请参见#writeSerializable）。请注意，前面的所有类型都有相对高效的实现来写入包裹；必须依赖泛型序列化方法的效率要低得多，应该尽可能避免。
Parcelable对象使用Parcelable#writeToParcel写入，使用上下文标志0。序列化包含ParcelFileDescriptor的对象时，如果从绑定器调用返回文件描述符（其中应使用Parcelable#Parcelable _WRITE _RETURN _值），可能会导致文件描述符泄漏。
