Java 如何在可单击的项目上打开新活动？

我是Java的初学者，我为他下载了一个网格模板。我的时间很短，因此无法从这一切中学习。请帮助我使用这段代码，如何创建带有新活动的可点击项目，哪些有白页

主要活动

public class MainActivity extends AppCompatActivity {

private RecyclerView recyclerView;
private AlbumsAdapter adapter;
private List<Album> albumList;


@Override

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    initCollapsingToolbar();

    recyclerView = (RecyclerView) findViewById(R.id.recycler_view);

    albumList = new ArrayList<>();
    adapter = new AlbumsAdapter(this, albumList);

    RecyclerView.LayoutManager mLayoutManager = new GridLayoutManager(this, 2);
    recyclerView.setLayoutManager(mLayoutManager);
    recyclerView.addItemDecoration(new GridSpacingItemDecoration(2, dpToPx(10), true));
    recyclerView.setItemAnimator(new DefaultItemAnimator());
    recyclerView.setAdapter(adapter);

    prepareAlbums();

    try {
        Glide.with(this).load(R.drawable.bghedb).into((ImageView) findViewById(R.id.backdrop));
    } catch (Exception e) {
        e.printStackTrace();
    }
}

/**
 * Initializing collapsing toolbar
 * Will show and hide the toolbar title on scroll
 */
private void initCollapsingToolbar() {
    final CollapsingToolbarLayout collapsingToolbar =
            (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
    collapsingToolbar.setTitle(" ");
    AppBarLayout appBarLayout = (AppBarLayout) findViewById(R.id.appbar);
    appBarLayout.setExpanded(true);

    // hiding & showing the title when toolbar expanded & collapsed
    appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
        boolean isShow = false;
        int scrollRange = -1;

        @Override
        public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
            if (scrollRange == -1) {
                scrollRange = appBarLayout.getTotalScrollRange();
            }
            if (scrollRange + verticalOffset == 0) {
                collapsingToolbar.setTitle(getString(R.string.app_name));
                isShow = true;

                isShow = false;
            }
        }
    });

有人能帮我吗？我是否需要把每一个字符串href改成新的白色页面，我的问题是以后有没有人有空闲时间关心我从0安卓学习？谢谢。只需添加这些行即可

holder.overflow.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent = new Intent(context, YourActivity.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
        context.startActivity(intent);
    }
});

我很难理解你想要什么你能澄清你的问题吗？但如何点击所有字符串？当点击字符串需要打开新的白色页面时。@OpreaCatalin，视图中还有三个小部件，所以像溢出一样附加在点击Litener上。是的，我可以，但这不是共享电子邮件地址以避免垃圾邮件的合适论坛。希望您能理解：）

public Album(String name, int numOfSongs, int thumbnail) {
    this.name = name;
    this.numOfSongs = numOfSongs;
    this.thumbnail = thumbnail;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getNumOfSongs() {
    return numOfSongs;
}

public void setNumOfSongs(int numOfSongs) {
    this.numOfSongs = numOfSongs;
}

public int getThumbnail() {
    return thumbnail;
}

public void setThumbnail(int thumbnail) {
    this.thumbnail = thumbnail;
}

holder.overflow.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent = new Intent(context, YourActivity.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
        context.startActivity(intent);
    }
});
