通过媒体录制器MediaRecorder实现MediaRecorder是Android自带的音频和视频录制工具它通过操纵摄像头和麦克风完成媒体录制既可录制视频又可单独录制音频。
MediaRecorder常用方法(录音与录像通用)
reset重置录制资源。prepare准备录制。start开始录制。stop结束录制。release释放录制资源。setOnErrorListener设置错误监听器。可监听服务器异常和未知错误的事件。需要实现接口MediaRecorder.OnErrorListener的onError方法。setOnInfoListener设置信息监听器。可监听录制结束事件包括达到录制时长或达到录制大小。需要实现接口MediaRecorder.OnInfoListener的onInfo方法。setMaxDuration设置可录制的最大时长单位毫秒。setMaxFileSize设置可录制的最大文件大小单位字节。setOutputFile设置输出文件的路径。
setOutputFormat设置媒体输出格式OutputFormat类的输出格式格式分类扩展名格式说明AMR_NB音频.amr窄带格式AMR_WB音频.amr宽带格式AAC_ADTS音频.aac高级的音频传输流格式MPEG_4视频.mp4MPEG4格式THREE_GPP视频.3gp3GP格式
音频录制示例上代码
一.权限添加
uses-permission android:nameandroid.permission.READ_MEDIA_IMAGES /uses-permission android:nameandroid.permission.READ_MEDIA_AUDIO /uses-permission android:nameandroid.permission.READ_MEDIA_VIDEO /uses-permission android:nameandroid.permission.RECORD_AUDIO/uses-permission android:nameandroid.permission.READ_EXTERNAL_STORAGE android:maxSdkVersion32/uses-permission android:nameandroid.permission.WRITE_EXTERNAL_STORAGE android:maxSdkVersion32/
权限区分版本33及以上和以下
动态权限请求
使用权限请求库在app的build.gradle添加
// 权限请求implementation com.guolindev.permissionx:permissionx:1.7.1 使用音频抖动动效
// https://github.com/xfans/VoiceWaveView
implementation com.github.xfans:VoiceWaveView:1.0.2

设置dialog样式在style.xml
!-- 这里的parent必须是Theme.AppCompat.Dialog --style nameAddDialogTheme parentTheme.AppCompat.Dialog!-- 这两个属性对于一个常规的Dialog一般必须设置的--!-- 这两个属性按照下面的值设置之后确保了弹窗的实际显示效果跟你在layout文件中的定义效果是一样的 --item nameandroid:windowIsFloatingfalse/item
