這幾天需要搞一個(gè)Android視頻通話功能，從最簡單的視頻錄制開始，網(wǎng)上例子大多不完整。下面的示例參考過別人的代碼，還是拿出來給需要的朋友分享下。

Activity類: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;//創(chuàng)建文件夾存放視頻    
        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);//創(chuàng)建臨時(shí)文件    
            recorder.setPreviewDisplay(mSurfaceHolder.getSurface());//預(yù)覽    
            recorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);//視頻源    
            recorder.setAudioSource(MediaRecorder.AudioSource.MIC); //錄音源為麥克風(fēng)    
            recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);//輸出格式為3gp    
            recorder.setVideoSize(800, 480);//視頻尺寸    
            recorder.setVideoFrameRate(15);//視頻幀頻率    
            recorder.setVideoEncoder(MediaRecorder.VideoEncoder.H263);//視頻編碼    
            recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);//音頻編碼    
            recorder.setMaxDuration(10000);//最大期限    
            recorder.setOutputFile(myRecAudioFile.getAbsolutePath());//保存路徑    
            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="錄制"    
          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>   

權(quán)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:label="@string/app_name">    
            <intent-filter>    
                <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.RECORD_AUDIO"/>
