Android[视频] camera 视频录制

由于camera已经被舍弃，建议使用替代类camera2。下篇文章会讲到camera2。切入主题。首先是权限，这个比较容易忘记申请。

<!-- 存储 -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

<!-- 网络权限 -->
<uses-permission android:name="android.permission.INTERNET" />

<!--摄像头-->
<uses-permission android:name="android.permission.CAMERA" />
<!--录音-->
<uses-permission android:name="android.permission.RECORD_AUDIO" />

视频录制需要存储权限、照相机权限、录音权限和网络权限。网络权限在这里并不是主要的。不过一般都顺手加上。毕竟网络是最常用的。

照相机权限和录音权限从Android6.0开始需要动态申请，申请方式Android6.0动态申请权限当然现在框架有很多，可以选择一种自己喜欢的使用。权限申请完成后，下面我们有就要自定义一个预览照相机拍摄画面的展示类了。有两个类可以选择 SurfaceView、SurfaceTexture 这里使用SurfaceView。不管怎么说没有比实现代码实在的东西了。<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"android:gravity="center_horizontal"><RelativeLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:layout_weight="1.0"><SurfaceViewandroid:id="@+id/surfaceview"android:layout_width="match_parent"android:layout_height="match_parent"/><Buttonandroid:id="@+id/btn_lamp"android:layout_width="30dp"android:layout_height="30dp"android:background="@drawable/btn_lamp_bg"android:layout_margin="@dimen/margin_10"android:layout_alignParentBottom="true"/><Buttonandroid:id="@+id/btn_lens"android:layout_width="30dp"android:layout_height="30dp"android:background="@drawable/lens"android:layout_margin="@dimen/margin_10"android:layout_alignParentBottom="true"android:layout_alignParentRight="true"/></RelativeLayout><ProgressBarandroid:id="@+id/progressBar"android:layout_width="match_parent"android:layout_height="5dp"style="@android:style/Widget.ProgressBar.Horizontal"android:progressDrawable="@drawable/progressbar_color"/></LinearLayout>
