Membuat Cardview Ala Google Play Musik
1. langkah pertama siapkan kurang lebih sepuluh gambar untuk tampilan cardviewnya. gambarnya bebas bisa dicari di google
2. selanjutnya tambahkan despendensi ini di build.gradle
compile 'com.android.support:design:25.2.0'
compile 'com.android.support:recyclerview-v7:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.android.support:recyclerview-v7:25.2.0'
compile 'com.android.support:cardview-v7:25.2.0'
compile 'com.github.bumptech.glide:glide:3.7.0'
3. kemudian sesuaikan style nya seperti dibawah, pada file styles.xml
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
4. langkah selanjutnya buat layout di activity_main seperti dibawah:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/main_content"
android:background="@android:color/white"
android:fitsSystemWindows="true"
tools:context="giviews.id.cardview.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="250dp"
android:fitsSystemWindows="true"
android:background="@color/colorAccent"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="@color/colorAccent"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:expandedTitleTextAppearance="@android:color/transparent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<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"
android:contentDescription="" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center_horizontal"
android:orientation="vertical">
<TextView
android:id="@+id/love_music"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/love_music"
android:textColor="@android:color/white"
android:textSize="30dp"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/this_session_top_20_songs"
android:textColor="@android:color/white"
android:textSize="18dp"/>
</LinearLayout>
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main"/>
</android.support.design.widget.CoordinatorLayout>
5. selanjutnya buat layout content_main.xml scriptnya seperti dibawah
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/white"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:showIn="@layout/activity_main"
tools:context="giviews.id.cardview.MainActivity">
<android.support.v7.widget.RecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clipToPadding="false"
android:scrollbars="vertical"/>
</RelativeLayout>
6. langkah berikutnya buat layout album_card.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:card_view="http://schemas.android.com/tools"
android:orientation="vertical"
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="5dp"
android:elevation="3dp"
card_view:cardCornerRadius="0dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="@+id/thumbnail"
android:layout_width="match_parent"
android:layout_height="160dp"
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:paddingTop="10dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:textColor="@color/album_title"
android:textSize="15dp" />
<TextView
android:id="@+id/count"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/title"
android:paddingBottom="5dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:textSize="12dp"/>
<ImageView
android:id="@+id/overflow"
android:layout_width="20dp"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:layout_below="@+id/thumbnail"
android:layout_marginTop="10dp"
android:scaleType="centerCrop"
android:src="?android:attr/floatingToolbarOpenDrawable" />
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
7. kemudian buat menu dengan nama menu_album.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="giviews.id.cardview.MainActivity">
<item
android:id="@+id/action_add_favourite"
android:actionViewClass="android.widget.SearchView"
android:orderInCategory="102"
android:title="Add to Favourite" />
<item
android:id="@+id/action_play_next"
android:actionViewClass="android.widget.SearchView"
android:orderInCategory="102"
android:title="Play Next" />
</menu>
8. Untuk MainActivity.java masukan script ini
package giviews.id.cardview;
import android.content.res.Resources;
import android.graphics.Rect;
import android.support.design.widget.AppBarLayout;
import android.support.design.widget.CollapsingToolbarLayout;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.DefaultItemAnimator;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.util.TypedValue;
import android.view.View;
import android.widget.ImageView;
import com.bumptech.glide.Glide;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private AlbumAdapter adapter;
private List<Album> albumList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//mengaktifkan toolbar
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
initCollapsingToolbar();
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
albumList = new ArrayList<>();
adapter = new AlbumAdapter(this, albumList);
RecyclerView.LayoutManager layoutManager = new GridLayoutManager(this, 2);
recyclerView.setLayoutManager(layoutManager);
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) {
e.printStackTrace();
}
}
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("Card View");
isShow = true;
} else if (isShow) {
collapsingToolbar.setTitle(" ");
isShow = false;
}
}
});
}
private void prepareAlbums() {
int[] covers = new int[]{
R.drawable.album1,
R.drawable.album2,
R.drawable.album3,
R.drawable.album4,
R.drawable.album5,
R.drawable.album6,
R.drawable.album7,
R.drawable.album8,
R.drawable.album9};
Album a = new Album("TARA", 13, covers[0]);
albumList.add(a);
a = new Album("Little Dragon", 8, covers[1]);
albumList.add(a);
a = new Album("The Titans", 11, covers[2]);
albumList.add(a);
a = new Album("Armada", 12, covers[3]);
albumList.add(a);
a = new Album("The Beatles", 20, covers[4]);
albumList.add(a);
a = new Album("Bellamy Brothers", 8, covers[5]);
albumList.add(a);
a = new Album("The Beatles", 10, covers[6]);
albumList.add(a);
a = new Album("Noah", 14, covers[7]);
albumList.add(a);
a = new Album("Geisha", 15, covers[8]);
albumList.add(a);
adapter.notifyDataSetChanged();
}
public class GridSpacingItemDecoration extends RecyclerView.ItemDecoration {
private int spanCount;
private int spacing;
private boolean includeEdge;
public GridSpacingItemDecoration(int i, Object dpToPx, boolean b) {
this.spanCount = spanCount;
this.spacing = spacing;
this.includeEdge = includeEdge;
}
@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
int position = parent.getChildAdapterPosition(view); // item position
int column = position - spanCount; // item column
//super.getItemOffsets(outRect, view, parent, state);
if (includeEdge) {
outRect.left = spacing - column * spacing / spanCount;
outRect.right = (column + 1) * spacing / spanCount;
if (position < spanCount) {
outRect.top = spacing;
}
outRect.bottom = spacing;
} else {
outRect.left = column * spacing - spanCount;
outRect.right = spacing - (column + 1) * spacing - spanCount;
if (position >= spanCount) {
outRect.top = spacing;
}
}
}
}
// convert dp to px
private Object dpToPx(int dp) {
Resources r = getResources();
return Math.round(TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dp, r.getDisplayMetrics()));
}
}
9. Kemudian buat Class baru dengan nama AlbumAdapter dan maukan script ini
package giviews.id.cardview;
import android.content.Context;
import android.support.v7.widget.PopupMenu;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import com.bumptech.glide.Glide;
import java.util.List;
/**
* Created by asus on 02/07/2017.
*/
class AlbumAdapter extends RecyclerView.Adapter<AlbumAdapter.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 AlbumAdapter(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 v) {
showPopupMenu(holder.overflow);
}
});
}
// showing popup menu when tapping 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 item
private 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();
}
}
10. terakhir buat class Album dan masukan script ini :
package giviews.id.cardview;
/**
* Created by asus on 02/07/2017.
*/
class Album {
private String name;
private int numOfSongs;
private int thumbnail;
public Album() {
}
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;
}
}
11. Untuk String isikan kode berikut
<resources>
<string name="app_name">Cardview</string>
<string name="love_music">LOVE MUSIC</string>
<string name="this_session_top_20_songs">This session top 20 songs</string>
</resources>
Selanjutnya silakan test aplikasi anda, jika cardviewnya muncul seperti gambar di atas Selamat anda telah berhasil. jika ada pertanyaan silakan kirimkan pada kolom komentar dibawah.
