**一、点击按钮进行录制**  
首先要获取摄像拍照的权限和读取权限

<uses-permission android:name="android.permission.CAMERA" />
        <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
        <uses-permission android:name="android.permission.RECORD_AUDIO" />

布局文件如下：

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/activity_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        tools:context="com.yus.videorecording.MainActivity">
    
        <Button
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/open"
            android:text="开始录制"
            />
    </RelativeLayout>

**二、下面是录制时的主要代码，录制完成保存到本地，在进行播放：**

public class VideoRecordActivity extends Activity implements MediaRecorder.OnErrorListener, View.OnClickListener {
        private ImageView iv_cancel,iv_save;
        private SurfaceView mSurfaceView;
        private SurfaceHolder mSurfaceHolder;
        private MediaRecorder mMediaRecorder;
        private Camera mCamera;
    
        private CircleButtonView cbv_record;
        private File mRecordFile = null;// 文件
        private int mRotationRecord=90;//视频输出角度 0横屏  90竖屏  180反横屏
        private boolean isRecording;//正在录制
        private float mWindowW;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            //全屏无标题
            requestWindowFeature(Window.FEATURE_NO_TITLE);
            getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,
                    WindowManager.LayoutParams. FLAG_FULLSCREEN);
            super.onCreate(savedInstanceState);
            setContentView(R.layout.video_record_activity);
            initView();
            initData();
            setListener();
        }
    
        private void initData() {
            DisplayMetrics metric = new DisplayMetrics();
            getWindowManager().getDefaultDisplay().getMetrics(metric);
            mWindowW = metric.widthPixels;     // 屏幕宽度（像素）
    
        }
    
        @Override
        protected void onResume() {
            super.onResume();
            cbv_record.setVisibility(View.VISIBLE);
            iv_cancel.setVisibility(View.GONE);
            iv_save.setVisibility(View.GONE);
            if(mRecordFile!=null){
                mRecordFile.getAbsoluteFile().delete();
            }
        }
    
        private void setListener() {
            cbv_record.setOnLongClickListener(new CircleButtonView.OnLongClickListener() {
                @Override
                public void onLongClick() {
                    isRecording=true;
                    startRecord();
                }
    
                @Override
                public void onNoMinRecord(int currentTime) {
                    isRecording=false;
                    Toast.makeText(VideoRecordActivity.this, "录制视频太短", Toast.LENGTH_SHORT).show();
                    if(mRecordFile.getAbsoluteFile()!=null){
                        mRecordFile.getAbsoluteFile().delete();
                    }
                }
    
                @Override
                public void onRecordFinishedListener() {
                    Log.e("yufs","视频录制完成:path=="+mRecordFile.getAbsolutePath());
                    isRecording=false;
                    stopRecord();
                    cbv_record.setVisibility(View.GONE);
                    iv_cancel.setVisibility(View.VISIBLE);
                    iv_save.setVisibility(View.VISIBLE);
                }
            });
    
            //手机旋转监听
            OrientationEventListener orientationEventListener=new OrientationEventListener(this) {
