想在单个页面中添加多个 videoview

Question

所以，基本上我想在单个页面中添加多个视频。我尝试添加它仍然不是 working.there 是一些 bug.Bcoz 当我运行应用程序没有 error.I 尝试使用代码进行试验仍然没有 working.I 附上了我的 bvideos.xml 和相应的 java 文件。

这是我的 bvideos.java 文件

public class bvideos extends AppCompatActivity {

    private VideoView videoView;
    private MediaController mediaController;


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

       /* VideoView videoView  = findViewById(R.id.video_view1);
        videoView.setVideoPath("android.resource://"+getPackageName()+"/"+R.raw.bvideo1);
        MediaController mediaController = new MediaController(this);
        mediaController.setAnchorView(videoView);
        videoView.setMediaController(mediaController);*/



        Button photo = (Button) findViewById(R.id.bphoto);
        photo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent y = new Intent(bvideos.this, mainpage.class);
                startActivity(y);

            }
        });


        videoView = findViewById(R.id.video_view1);

        /*String fullScreen =  getIntent().getStringExtra("fullScreenInd");
        if("y".equals(fullScreen)){
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
            getSupportActionBar().hide();
        }*/

        Uri videoUri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.bvideo1);

        videoView.setVideoURI(videoUri);

        mediaController = new FullScreenMediaController(this);
        mediaController.setAnchorView(videoView);

        videoView.setMediaController(mediaController);
        videoView.start();



        videoView = findViewById(R.id.video_view2);

        /*String fullScreen =  getIntent().getStringExtra("fullScreenInd");
        if("y".equals(fullScreen)){
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
            getSupportActionBar().hide();
        }*/

        Uri videoUri1 = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.bvideo2);

        videoView.setVideoURI(videoUri1);

        mediaController = new FullScreenMediaController(this);
        mediaController.setAnchorView(videoView);

        videoView.setMediaController(mediaController);
        videoView.start();





    }
}

Answer 1

您缺少 start();称呼。尝试添加

videoView.start();

之后

videoView.setVideoURI(uri);

想在单个页面中添加多个 videoview

want to add multiple videoview in single page

java

android

android-layout

android-studio
