这几天需要搞一个Android视频通话功能,从最简单的视频录制开始,网上例子大多不完整。下面的示例参考过别人的代码,还是拿出来给需要的朋友分享下。
Activity类:VideoActivity
- package com.media.Media;
- import java.io.File;
- import java.io.IOException;
- import android.app.Activity;
- import android.media.MediaRecorder;
- import android.os.Bundle;
- import android.os.Environment;
- import android.view.SurfaceHolder;
- import android.view.SurfaceView;
- import android.view.View;
- import android.view.View.OnClickListener;
- import android.widget.Button;
- public class VideoActivity extends Activity {
- private File myRecAudioFile;
- private SurfaceView mSurfaceView;
- private SurfaceHolder mSurfaceHolder;
- private Button buttonStart;
- private Button buttonStop;
- private File dir;
- private MediaRecorder recorder;
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.video);
- mSurfaceView = (SurfaceView) findViewById(R.id.videoView);
- mSurfaceHolder = mSurfaceView.getHolder();
- mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
- buttonStart=(Button)findViewById(R.id.start);
- buttonStop=(Button)findViewById(R.id.stop);
- File defaultDir = Environment.getExternalStorageDirectory();
- String path = defaultDir.getAbsolutePath()+File.separator+"V"+File.separator;//创建文件夹存放视频
- dir = new File(path);
- if(!dir.exists()){
- dir.mkdir();
- }
- recorder = new MediaRecorder();
- buttonStart.setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- recorder();
- }
- });
- buttonStop.setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- recorder.stop();
- recorder.reset();
- recorder.release();
- recorder=null;
- }
- });
- }
- public void recorder() {
- try {
- myRecAudioFile = File.createTempFile("video", ".3gp",dir);//创建临时文件
- recorder.setPreviewDisplay(mSurfaceHolder.getSurface());//预览
- recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);//视频源
- recorder.setAudioSource(MediaRecorder.AudioSource.MIC); //录音源为麦克风
- recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);//输出格式为3gp
- recorder.setVideoSize(800, 480);//视频尺寸
- recorder.setVideoFrameRate(15);//视频帧频率
- recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);//视频编码
- recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);//音频编码
- recorder.setMaxDuration(10000);//最大期限
- recorder.setOutputFile(myRecAudioFile.getAbsolutePath());//保存路径
- recorder.prepare();
- recorder.start();
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- }
界面:video.xml
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout
- xmlns:android="http://schemas.android.com/apk/res/android"
- android:orientation="vertical"
- android:layout_width="fill_parent"
- android:layout_height="fill_parent">
- <SurfaceView android:id="@+id/videoView"
- android:visibility="visible"
- android:layout_width="320px"
- android:layout_height="240px">
- </SurfaceView>
- <RelativeLayout
- android:layout_width="fill_parent"
- android:layout_height="wrap_content">
- <Button
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="录制"
- android:id="@+id/start"/>
- <Button
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_toRightOf="@id/start"
- android:text="停止"
- android:id="@+id/stop"/>
- </RelativeLayout>
- </LinearLayout>
权限配置:AndroidManifest.xml
- <?xml version="1.0" encoding="utf-8"?>
- <manifest xmlns:android="http://schemas.android.com/apk/res/android"
- package="com.media.Media"
- android:versionCode="1"
- android:versionName="1.0">
- <application android:icon="@drawable/rabbit" android:label="@string/app_name">
- <activity android:name=".VideoActivity"
- android:label="@string/app_name">

- <action android:name="android.intent.action.MAIN" />
- <category android:name="android.intent.category.LAUNCHER" />
- </intent-filter>
- </activity>
- </application>
- <uses-sdk android:minSdkVersion="7" />
- <uses-permission android:name="android.permission.CAMERA"/>
- <uses-permission android:name="android.permission.RECORD_AUDIO"/>
