Can one use cardview for listview item and how

Question

I would like to implement CardView in my app so that all ListView items are CardViews. Is it as simple as encapsulating a ListVi

Answer 1

It's better to use CardView with RecyclerView, here is an example.

• activity_main.xml (it contains the recyclerview)

• cardview.xml

• buid.gradle(Module:app)

  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:cardview-v7:23.0.+'
      compile 'com.android.support:recyclerview-v7:23.0.+'
  }
  

• RecyclerViewAdapter.java

  public class RecyclerViewAdapter extends RecyclerView.Adapter {
      public ArrayList myValues;
      public RecyclerViewAdapter (ArrayList myValues){
          this.myValues= myValues;
      }
  
      @Override
      public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
          View listItem = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview.xml, parent, false);
          return new MyViewHolder(listItem);
      }
  
      @Override
      public void onBindViewHolder(MyViewHolder holder, int position) {
           holder.myTextView.setText(myValues.get(position));
      }
  
  
      @Override
      public int getItemCount() {
          return myValues.size();
      }
  
      public static class MyViewHolder extends RecyclerView.ViewHolder {
          private TextView myTextView;
          public MyViewHolder(View itemView) {
              super(itemView);
          myTextView = (TextView)itemView.findViewById(R.id.text_cardview);
          }
      }
  }
  

• MainActivity.java

  public class MainActivity extends AppCompatActivity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  
      ArrayList myValues = new ArrayList();
  
      //Populate the ArrayList with your own values
      myValues.add("KitKat");
      myValues.add("Lollipop");
      myValues.add("Marshmallow");
  
      RecyclerViewAdapter adapter = new RecyclerViewAdapter(myValues);
      RecyclerView myView =  (RecyclerView)findViewById(R.id.recyclerview);
      myView.setHasFixedSize(true);
      myView.setAdapter(adapter);
      LinearLayoutManager llm = new LinearLayoutManager(this);
      llm.setOrientation(LinearLayoutManager.VERTICAL);
      myView.setLayoutManager(llm);
   }     
   }
