1. Basic ListView:

Source code:

package com.example.vilh.demobasiclistview;
    
    import android.content.Intent;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.view.View;
    import android.widget.AdapterView;
    import android.widget.ArrayAdapter;
    import android.widget.Button;
    import android.widget.ListView;
    import android.widget.Toast;
    
    import java.util.ArrayList;
    import java.util.List;
    
    public class BasicLView extends AppCompatActivity {
    
        Button btnClicked;
        ListView lstView;
    
        @Override    protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_basic_lview);
    
            lstView = (ListView)findViewById(R.id.listView);
            btnClicked = (Button)findViewById(R.id.buttonClick);
    
            btnClicked.setOnClickListener(new View.OnClickListener() {
                @Override            public void onClick(View v) {
                    Intent main = new Intent(BasicLView.this, MainActivity.class);
                    startActivity(main);
                }
            });
    
    
            final ArrayList<String> arMonHoc = new ArrayList<String>();
            arMonHoc.add("Game Phong Thần");
            arMonHoc.add("Game Võ Lâm 1");
            arMonHoc.add("Game Kiếm Thế");
            arMonHoc.add("Game Võ Lâm 2");
            arMonHoc.add("Game Thiên Long");
            arMonHoc.add("Game Hoa Thiên Cốt");
    
    
            ArrayAdapter adapter = new ArrayAdapter(
                    BasicLView.this,
                    android.R.layout.simple_list_item_1,
                    arMonHoc
            );
    
    
            lstView.setAdapter(adapter);
    
            lstView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    Toast.makeText(
                            getApplicationContext(),
                            arMonHoc.get(position),
                            Toast.LENGTH_SHORT                ).show();
                }
            });
    
    
        }
    }
    

2. Custom ListView

Use basic ListView:

Drag 2 pictures to drawable folder
Choose Proejcts before do that!

Create activity_dong_food.xml (Interface)

Source code:

clsFood.java

package com.example.vilh.democustomelistview;
    
    /** * Created by Zidane-huuvi168@gmail.com on 4/19/2016. */public class clsFood {
        public String Name;
        public Integer Money;
        public Integer Position;
    
        public clsFood(String name, Integer m, Integer pos) {
            Name = name;
            Money = m;
            Position = pos; /* position of image */
        }
    }
    

ListAdapter.java

package com.example.vilh.democustomelistview;
    
    import android.content.Context;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.ArrayAdapter;
    import android.widget.ImageView;
    import android.widget.TextView;
    
    import java.util.List;
    
    public class ListAdapter extends ArrayAdapter<clsFood> {
    
          
    
        public ListAdapter(Context context, int textViewResourceId) {
            super(context, textViewResourceId);
        }
    
        // context màn hinh đang đứng    
        // resource = layout đang đứng    
    
    
        public ListAdapter(Context context, int resource, List<clsFood> items) {
            super(context, resource, items);
        }
    
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
    
            View v = convertView;
    
            if (v == null) {
                LayoutInflater vi;
                vi = LayoutInflater.from(getContext());
                v = vi.inflate(R.layout.activity_dong_food, null);
            }
    
            clsFood p = getItem(position);
    
            if (p != null) {
                // Anh xa + Gan gia tri        
                TextView tt1 = (TextView) v.findViewById(R.id.textViewNameCourses);
                tt1.setText(p.Name);
    
                TextView tt2 = (TextView) v.findViewById(R.id.textViewYear);
                tt2.setText(String.valueOf(p.Money));
    
    
                ImageView im1 = (ImageView)v.findViewById(R.id.imageViewDescription);
                im1.setImageResource(p.Position);
    
            }
    
            // giao diện từng dòng        return v;
        }
    
    }

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_custom_lview);
    
            lstCourses = (ListView)findViewById(R.id.listViewCourses);
            btnBacked = (Button)findViewById(R.id.buttonBack);
    
            btnBacked.setOnClickListener(new View.OnClickListener() {

            ListAdapter adapter = new ListAdapter(
                    CustomLView.this,
                    R.layout.activity_dong_food, // layout tu build 
                    arFood
            );
    
            lstCourses.setAdapter(adapter);
