本文实例为大家分享了Android仿微信长按录制视频并播放功能的具体代码，供大家参考，具体内容如下
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、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) {
@Override
public void onOrientationChanged(int rotation) {
//录制的过程不改变
if(isRecording){
return;
}
if (((rotation >= 0) && (rotation <= 30)) || (rotation >= 330)) {
// 竖屏拍摄
mRotationRecord=90;
} else if (((rotation >= 230) && (rotation <= 310))) {
// 横屏拍摄
mRotationRecord=0;
} else if (rotation > 30 && rotation < 95) {
// 反横屏拍摄
mRotationRecord=180;
}
}
};
orientationEventListener.enable();
iv_cancel.setOnClickListener(this);
iv_save.setOnClickListener(this);
}
private void startRecord() {
//初始录制视频保存路径
createRecordDir();

}
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.iv_cancel:

三、录制完成，获取录制的视频并播放
代码如下：
public class VideoPlayActivity extends Activity implements MediaPlayer.OnPreparedListener, TextureVideoView.OnPlayStateListener, MediaPlayer.OnInfoListener, MediaPlayer.OnVideoSizeChangedListener, MediaPlayer.OnErrorListener, MediaPlayer.OnSeekCompleteListener {
private VideoViewTouch mVideoView;
private RelativeLayout rl_loading;
private Context mContext;
/** 播放路径 */
private String mSourcePath;
private Intent uploadService;//视频上传服务
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video_preview);
initView();
setListener();
initData();
}
private void initData() {
//本地视频路径
mSourcePath=getIntent().getStringExtra("source");
//播放视屏
parseIntentUrl(getIntent());
}
private void parseIntentUrl(Intent intent) {
mVideoView.setVideoPath(mSourcePath);
}
private void setListener() {
mVideoView.setOnPreparedListener(this);
mVideoView.setOnPlayStateListener(this);
mVideoView.setOnTouchEventListener(mOnVideoTouchListener);
mVideoView.setOnInfoListener(this);
mVideoView.setOnVideoSizeChangedListener(this);
mVideoView.setOnErrorListener(this);
mVideoView.setOnSeekCompleteListener(this);
}
private void initView() {
mVideoView= (VideoViewTouch) findViewById(R.id.preview);
rl_loading= (RelativeLayout) findViewById(R.id.video_loading);
View preview_layout = findViewById(R.id.preview_layout);
preview_layout.setVisibility(View.VISIBLE);
}
private VideoViewTouch.OnTouchEventListener mOnVideoTouchListener = new VideoViewTouch.OnTouchEventListener() {
@Override
public boolean onClick() {
if (mVideoView.isPlaying()) {
mVideoView.pauseClearDelayed();
} else {
mVideoView.start();
}
return true;
}
@Override
public void onVideoViewDown() {
}
@Override
public void onVideoViewUp() {
}
};
@Override
public void onPrepared(MediaPlayer mp) {
//获取视频的宽和高
int videoWidth = mp.getVideoWidth();
int videoHeight = mp.getVideoHeight();
Log.e("yufs","视频的宽:" videoWidth ",视频的高:" videoHeight);
//重新设置TextureView宽和高
mVideoView.resize();
//开始播放
rl_loading.setVisibility(View.GONE);
mVideoView.start();
}
@Override
public void onStateChanged(boolean isPlaying) {
}
@Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
return false;
}
@Override
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
}
@Override
public boolean onError(MediaPlayer mp, int what, int extra) {
return false;
}
@Override
public void onSeekComplete(MediaPlayer mp) {
}
@Override
protected void onDestroy() {
super.onDestroy();
}
}
