Android仿微信長(zhǎng)按錄制視頻并播放功能
更新時(shí)間：2021年05月27日 10:29:58 作者：志尊寶
這篇文章主要為大家詳細(xì)介紹了Android仿微信長(zhǎng)按錄制視頻并播放功能，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
本文實(shí)例為大家分享了Android仿微信長(zhǎng)按錄制視頻并播放功能的具體代碼，供大家參考，具體內(nèi)容如下
一、點(diǎn)擊按鈕進(jìn)行錄制
首先要獲取攝像拍照的權(quán)限和讀取權(quán)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="開(kāi)始錄制"
/>
</RelativeLayout>
二、錄制時(shí)的主要代碼，錄制完成保存到本地，在進(jìn)行播放：
public class VideoRecordActivity extends Activity implements MediaRecorder.OnErrorListener, View.OnClickListener {

private SurfaceView mSurfaceView;
private SurfaceHolder mSurfaceHolder;
private MediaRecorder mMediaRecorder;

}
}
@Override

stopRecord();
cbv_record.setVisibility(View.GONE);

}
});
//手機(jī)旋轉(zhuǎn)監(jiān)聽(tīng)

@Override

//錄制的過(guò)程不改變

}
private void startRecord() {

三、錄制完成，獲取錄制的視頻并播放
代碼如下：
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;
/** 播放路徑 */
private String mSourcePath;
private Intent uploadService;//視頻上傳服務(wù)
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_video_preview);
initView();
setListener();
initData();
}
private void initData() {
//本地視頻路徑
mSourcePath=getIntent().getStringExtra("source");
//播放視屏
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) {
//獲取視頻的寬和高
int videoWidth = mp.getVideoWidth();
int videoHeight = mp.getVideoHeight();
Log.e("yufs","視頻的寬:"+videoWidth+",視頻的高:"+videoHeight);
//重新設(shè)置TextureView寬和高
mVideoView.resize();
//開(kāi)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();
}
}
