Android之本地相冊图片选取和拍照以及图片剪辑

转载请注明出处：http://blog.csdn.net/loveyaozu/article/details/51160482

相信有非常多Android开发者在日常开发中，因为项目需求，须要我们的APP可以从相冊中选取图片并剪辑。以及拍照剪辑后上传的功能。

假设之前你没有做过这个功能，刚開始做的时候可能会遇到一些列的问题，这些问题大多是细节上的问题。今天，就依据自己的开发经验，给大家提供一套完毕的相冊图片选取剪辑和拍照剪辑的代码事例。我提供的代码可能还会存在一些问题，大家可以相互交流学习。

这里会给大家提供一些我整理的一些图片处理的工具类，供大家使用。

这里给大家展示一个简单的拍照，相冊图片选取，剪辑图片的样例demo。

首先创建activity_main.xml布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="${relativePackage}.${activityClass}" >

    <Button
        android:id="@+id/options"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp"
        android:gravity="center"
        android:textSize="15sp"
        android:text="@string/options_choose" />

    <TextView
        android:id="@+id/small_img_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp"
        android:textSize="15sp"/>

    <ImageView
        android:id="@+id/small_img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:contentDescription="@string/app_name" />

    <TextView
        android:id="@+id/clip_pic_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp"
        android:textSize="15sp"/>

    <ImageView
        android:id="@+id/clip_pic"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:contentDescription="@string/app_name" />

</LinearLayout>

结合上面的PhotoUtils实现拍照。相冊图片选取。图片剪辑功能。

	protected void options() {
