这是与自定义项目 –

recyclerview好吧，我会看到它。 – SovietSenpai

它可以通过各种方式完成。它只取决于你如何定制你的布局。可以做到这一点由....

1-与白色背景与使用帧布局图像视图和文字图像1对图1周的TextView内部...

2-线性布局。

3-图片中的视图是一个带cardview的回收视图。使用回收和卡，您需要支持设计相依..

// RecyclerView 
compile 'com.android.support:recyclerview-v7:23.3.+' 

// CardView 
compile 'com.android.support:cardview-v7:23.3.+'

第三个选项就是我正在寻找的。谢谢兄弟.. – SovietSenpai

@SovietSenpai享受编码 –

你必须使用循环视图与cardview。

要在您的应用中使用CardView，请在build.gradle中添加CardView依赖项并同步项目。

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.3.0' 
    compile 'com.android.support:design:23.3.0' 
    // RecyclerView 
    compile 'com.android.support:recyclerview-v7:23.3.+' 
    // CardView 
    compile 'com.android.support:cardview-v7:23.3.+' 
    // Glide 
    compile 'com.github.bumptech.glide:glide:3.7.0' 
}

后您创建一个XML卡片视图

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:card_view="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"> 

    <android.support.v7.widget.CardView 
     android:id="@+id/card_view" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_gravity="center" 
     android:layout_margin="@dimen/card_margin" 
     android:elevation="3dp" 
     card_view:cardCornerRadius="@dimen/card_album_radius"> 

     <RelativeLayout 
      android:layout_width="match_parent" 
      android:layout_height="match_parent"> 

      <ImageView 
       android:id="@+id/thumbnail" 
       android:layout_width="match_parent" 
       android:layout_height="@dimen/album_cover_height" 
       android:background="?attr/selectableItemBackgroundBorderless" 
       android:clickable="true" 
       android:scaleType="fitXY" /> 

      <TextView 
       android:id="@+id/title" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:layout_below="@id/thumbnail" 
       android:paddingLeft="@dimen/album_title_padding" 
       android:paddingRight="@dimen/album_title_padding" 
       android:paddingTop="@dimen/album_title_padding" 
       android:textColor="@color/album_title" 
       android:textSize="@dimen/album_title" /> 

      <TextView 
       android:id="@+id/count" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:layout_below="@id/title" 
       android:paddingBottom="@dimen/songs_count_padding_bottom" 
       android:paddingLeft="@dimen/album_title_padding" 
       android:paddingRight="@dimen/album_title_padding" 
       android:textSize="@dimen/songs_count" /> 

      <ImageView 
       android:id="@+id/overflow" 
       android:layout_width="@dimen/ic_album_overflow_width" 
       android:layout_height="@dimen/ic_album_overflow_height" 
       android:layout_alignParentRight="true" 
       android:layout_below="@id/thumbnail" 
       android:layout_marginTop="@dimen/ic_album_overflow_margin_top" 
       android:scaleType="centerCrop" 
       android:src="@drawable/ic_dots" /> 

     </RelativeLayout> 

    </android.support.v7.widget.CardView> 

</LinearLayout>

然后，您可以创建为

public class AlbumsAdapter extends RecyclerView.Adapter<AlbumsAdapter.MyViewHolder> { 

    private Context mContext; 
    private List<Album> albumList; 

    public class MyViewHolder extends RecyclerView.ViewHolder { 
     public TextView title, count; 
     public ImageView thumbnail, overflow; 

     public MyViewHolder(View view) { 
      super(view); 
      title = (TextView) view.findViewById(R.id.title); 
      count = (TextView) view.findViewById(R.id.count); 
      thumbnail = (ImageView) view.findViewById(R.id.thumbnail); 
      overflow = (ImageView) view.findViewById(R.id.overflow); 
     } 
    } 


    public AlbumsAdapter(Context mContext, List<Album> albumList) { 
     this.mContext = mContext; 
     this.albumList = albumList; 
    } 

    @Override 
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View itemView = LayoutInflater.from(parent.getContext()) 
       .inflate(R.layout.album_card, parent, false); 

     return new MyViewHolder(itemView); 
    } 

    @Override 
    public void onBindViewHolder(final MyViewHolder holder, int position) { 
     Album album = albumList.get(position); 
     holder.title.setText(album.getName()); 
     holder.count.setText(album.getNumOfSongs() + " songs"); 

     // loading album cover using Glide library 
     Glide.with(mContext).load(album.getThumbnail()).into(holder.thumbnail); 

     holder.overflow.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       showPopupMenu(holder.overflow); 
      } 
     }); 
    } 

    /** 
    * Showing popup menu when tapping on 3 dots 
    */ 
    private void showPopupMenu(View view) { 
     // inflate menu 
     PopupMenu popup = new PopupMenu(mContext, view); 
     MenuInflater inflater = popup.getMenuInflater(); 
     inflater.inflate(R.menu.menu_album, popup.getMenu()); 
     popup.setOnMenuItemClickListener(new MyMenuItemClickListener()); 
     popup.show(); 
    } 

    /** 
    * Click listener for popup menu items 
    */ 
    class MyMenuItemClickListener implements PopupMenu.OnMenuItemClickListener { 

     public MyMenuItemClickListener() { 
     } 

     @Override 
     public boolean onMenuItemClick(MenuItem menuItem) { 
      switch (menuItem.getItemId()) { 
       case R.id.action_add_favourite: 
        Toast.makeText(mContext, "Add to favourite", Toast.LENGTH_SHORT).show(); 
        return true; 
       case R.id.action_play_next: 
        Toast.makeText(mContext, "Play next", Toast.LENGTH_SHORT).show(); 
        return true; 
       default: 
      } 
      return false; 
     } 
    } 

    @Override 
    public int getItemCount() { 
     return albumList.size(); 
    } 
}

该适配器是活动的main.xml

<?xml version="1.0" encoding="utf-8"?> 
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"

      <RelativeLayout 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content"> 

       <ImageView 
        android:id="@+id/backdrop" 
        android:layout_width="match_parent" 
        android:layout_height="match_parent" 
        android:fitsSystemWindows="true" 
        android:scaleType="centerCrop" 
        app:layout_collapseMode="parallax" /> 

       <LinearLayout 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:layout_centerInParent="true" 
        android:gravity="center_horizontal" 
        android:orientation="vertical"> 

        <TextView

         android:text="@string/backdrop_title"

        <TextView

         android:textSize="@dimen/backdrop_subtitle" /> 

       </LinearLayout> 
      </RelativeLayout> 

      <android.support.v7.widget.Toolbar 
       android:id="@+id/toolbar"

     </android.support.design.widget.CollapsingToolbarLayout> 

    </android.support.design.widget.AppBarLayout> 

    <include layout="@layout/content_main" /> 

</android.support.design.widget.CoordinatorLayout>

这是content_main.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"

    tools:showIn="@layout/activity_main"> 

    <android.support.v7.widget.RecyclerView

     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:clipToPadding="false" 
     android:scrollbars="vertical" /> 

</RelativeLayout>

之后，终于写在MainActivity

public class MainActivity extends AppCompatActivity { 

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

    @Override

     recyclerView.addItemDecoration(new GridSpacingItemDecoration(2, dpToPx(10), true)); 
     recyclerView.setItemAnimator(new DefaultItemAnimator()); 
     recyclerView.setAdapter(adapter); 

     prepareAlbums(); 

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

      boolean isShow = false; 
      int scrollRange = -1; 

      @Override
