Question

当我尝试在Android应用程序中播放视频时，收到消息“无法播放此视频”。我使用VideoView的活动：

package midamcorp.com.burgerkingapp;

import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ImageButton;
import android.widget.VideoView;

import java.net.URI;

public class videoViewer extends AppCompatActivity {
VideoView vidView;
    ImageButton back;
    final String path = "www.midamcorp.com";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_video_viewer);

        vidView = (VideoView) findViewById(R.id.videoView);
        back = (ImageButton) findViewById(R.id.backButton);


        back.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
            }
        });

Intent i = getIntent();
        String vidPath = i.getStringExtra("path");
       try {
           Uri.Builder builder = new Uri.Builder();
           builder.scheme("http");
           builder.authority(path);
           builder.appendPath("videos");
           builder.appendPath(vidPath);

           Uri uri = builder.build();
           Log.i("Uri is ", uri.toString());
           vidView.setVideoURI(uri);

           vidView.start();
       } catch (Exception e) {
           Log.e(this.getClass().toString(), "error with URI");
       }



    }
}

部分输出

05-11 08:30:05.022 21669-21669/midamcorp.com.burgerkingapp I/Uri is: http://www.midamcorp.com/videos/whopperDog.wmv
05-11 08:30:05.163 21669-21669/midamcorp.com.burgerkingapp W/MediaPlayer: Couldn't open file on client side; trying server side: java.io.FileNotFoundException: No content provider: http://www.midamcorp.com/videos/whopperDog.wmv

每当我在浏览器中导航到视频路径时，它会下载而不是播放，但我认为这可能与浏览器设置有关。这可能与这个问题有关吗？我真的很感激任何帮助。

你没有设置MediaController只是试试..

MediaController mediacontroller = new MediaController(
                       mContext);
                mediacontroller.setAnchorView(vidView );
                // Get the URL from String VideoURL
                Uri video = Uri.parse(vidPath);
                vidView .setMediaController(mediacontroller);
                vidView .setVideoURI(video);

你试过avi或mp4文件吗？我不认为Android在视频视图中支持wmv文件。
