Question

这是我在按钮点击时播放视频的完整代码，但每当我点击按钮时，模拟器屏幕上会出现一个消息框，显示“对不起，此视频无法播放”消息。不要知道我哪里错了。

Trialvideo.java文件

package android.com.trialvideo;

import android.app.Activity;
import android.graphics.PixelFormat;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.MediaController;
import android.widget.VideoView;

public class TrialVideoActivity extends Activity {
    /** Called when the activity is first created. */

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

 /**       // Video view: to view our video
        VideoView video = (VideoView) findViewById(R.id.surface_view);

        //set video path to our video(in this case man-cheetah-gazalle.3gp)
        video.setVideoPath("/raw/jeewan.mp4");
        video.start();

    **/    
     final Button play =(Button)findViewById(R.id.play);
        play.setOnClickListener(new OnClickListener(){
            public void onClick(View V){
                videoPlayer();

            }
        });}

        public void videoPlayer(){

            getWindow().setFormat(PixelFormat.TRANSLUCENT);

            VideoView videoHolder = (VideoView)findViewById(R.id.surface_view);

            videoHolder.setMediaController(new MediaController(this));

            videoHolder.setVideoPath("/TrialVideo/raw/lic.3gp");

            videoHolder.requestFocus();
            videoHolder.start(); 

         }


    }

main.xml文件

Answer 1

您可以尝试以下代码：

VideoPlaying.java

public class VideoPlaying extends Activity {
    private MediaController mc;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    VideoView vd = (VideoView) findViewById(R.id.VideoView);
    Uri uri = Uri.parse("android.resource://" + getPackageName() + "/"+R.raw.VideoName);
    mc = new MediaController(this);
    vd.setMediaController(mc);
    vd.requestFocus();
    vd.setVideoURI(uri);
    vd.start();
    }
    }

main.xml中

<?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" android:gravity="center">
<VideoView android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:id="@+id/VideoView"></VideoView>

</LinearLayout>

将视频放在原始文件夹上并运行代码。有时视频将无法在模拟器上正确显示，请尝试在实际设备上进行检查。

Answer 2

Android没有C：驱动器。您需要将视频文件放在设备上（例如，将其复制到设备的外部存储设备），然后为VideoView提供文件的适当路径（例如，使用Environment.getExternalStorageDirectory()）。

视频播放器不工作！
