Android錄製視頻(五)

mainActivity如下:

package c.c;import android.net.Uri;import android.os.Bundle;import android.provider.MediaStore;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.VideoView;import android.app.Activity;import android.content.Intent;/** * Demo描述: * 利用系統網路攝影機拍攝視頻,且利用VideoView控制項播放視頻 */public class MainActivity extends Activity {private final static int VIDEO_CAPTURE=9527;private Uri mVideoUri;    private Button mCaptureButton;    private Button mPlayButton;    private VideoView mVideoView;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        init();    }    private void init(){    mCaptureButton=(Button) findViewById(R.id.capture_Button);    mCaptureButton.setOnClickListener(new ButtonClickListenerImpl());    mPlayButton=(Button) findViewById(R.id.play_Button);    mPlayButton.setEnabled(false);    mPlayButton.setOnClickListener(new ButtonClickListenerImpl());    mVideoView=(VideoView) findViewById(R.id.videoView);    }    private class ButtonClickListenerImpl implements OnClickListener{public void onClick(View v) {if (v.getId()==R.id.capture_Button) {Intent intent=new Intent(MediaStore.ACTION_VIDEO_CAPTURE);startActivityForResult(intent, VIDEO_CAPTURE);} else {                mVideoView.setVideoURI(mVideoUri);                mVideoView.start();}}        }    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {    super.onActivityResult(requestCode, resultCode, data);    if (resultCode==RESULT_OK&&requestCode==VIDEO_CAPTURE) {    mVideoUri=data.getData();    mPlayButton.setEnabled(true);}    }   }

main.xml如下:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <Button        android:id="@+id/capture_Button"        android:layout_width="150dip"        android:layout_height="wrap_content"        android:text="Video Capture" />    <Button        android:id="@+id/play_Button"        android:layout_width="150dip"        android:layout_height="wrap_content"        android:text="Video Play" />    <VideoView        android:id="@+id/videoView"        android:layout_width="wrap_content"        android:layout_height="wrap_content" /></LinearLayout>
