ApiDemos学习知识点之media-VideoView(10)

//将path变量设置为流视频URL或本地媒体文件路径。

先看一下图片

如图所示，本文主要是通过VideoView控件进行视频音频的播放。

先看一下布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <VideoView 
        android:id="@+id/surface_view" 
        android:layout_width="320px"
        android:layout_height="240px"
    />

</LinearLayout>

很简单的加入了一个VideoView的控件，并设置了宽和高

下面看一下代码及代码分析

public class VideoViewDemo extends Activity {

    /**
     * TODO: Set the path variable to a streaming video URL or a local media
     * file path.
     */
    private String path = "";
    private VideoView mVideoView;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.videoview);
        mVideoView = (VideoView) findViewById(R.id.surface_view);

        if (path == "") {
            // 告诉用户提供一个媒体文件URL /路径。.
            Toast.makeText(
                    VideoViewDemo.this,
                    "Please edit VideoViewDemo Activity, and set path"
                            + " variable to your media file URL/path",
                    Toast.LENGTH_LONG).show();

        } else {

            /*
             * 或者，对于流媒体，您可以使用mvideoview . setvideouri(uri . parse(URLstring));
             */
            mVideoView.setVideoPath(path);
            mVideoView.setMediaController(new MediaController(this));//添加播放控制条,还是自定义好点
            mVideoView.requestFocus();

        }
    }
}

//其他方法:mVideoView.pause();mVideoView.stop();mVideoView.resume();mVideoView.setOnPreparedListener(this);mVideoView.setOnErrorListener(this);mVideoView.setOnCompletionListener(this);**。
