先弄程式碼，怕今天太晚回來

MainActivity.java 部分

//package tw.com.fantasylin.listviewdemo;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.ArrayAdapter;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    String[] foods={"麵線","魯肉飯","小籠包","珍奶","肉包","雞排","便當","大冰奶","原來氏你","舒跑","咖啡"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        findViews();
    }
    private void findViews(){
        ListView listView=(ListView)findViewById(R.id.listView);
        listView.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,foods));


        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(MainActivity.this,foods[position], Toast.LENGTH_SHORT).show();
            }
        });

    }
}

activity_main.xml 部分

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="tw.com.fantasylin.listviewdemo.MainActivity">

    <ListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="30dp">


    </ListView>
</RelativeLayout>
