ListViewDemo

ListView Layout示例：
MainActivity.java中定义待显示的数据countryArray，

在activity_main中定义ListView，activity_listview中定义TextView。

 package com.example.shad_fnst.listviewdemo;
 
 import android.support.v7.app.ActionBarActivity;
 import android.os.Bundle;
 import android.view.Menu;
 import android.view.MenuItem;
 import android.widget.ArrayAdapter;
 import android.widget.ListView;
 
 public class MainActivity extends ActionBarActivity {
 
     String[] countryArray = {"China", "India", "America", "Japan", "England"};
 
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
 
         ArrayAdapter arrayAdapter = new ArrayAdapter(this, R.layout.activity_listview, countryArray);
         ListView listView = (ListView)findViewById(R.id.country_list);
         listView.setAdapter(arrayAdapter);
     }
 
     @Override
     public boolean onCreateOptionsMenu(Menu menu) {
         // Inflate the menu; this adds items to the action bar if it is present.
         getMenuInflater().inflate(R.menu.menu_main, menu);
         return true;
     }
 
     @Override
     public boolean onOptionsItemSelected(MenuItem item) {
         // Handle action bar item clicks here. The action bar will
         // automatically handle clicks on the Home/Up button, so long
         // as you specify a parent activity in AndroidManifest.xml.
         int id = item.getItemId();
 
         //noinspection SimplifiableIfStatement
         if (id == R.id.action_settings) {
             return true;
         }
 
         return super.onOptionsItemSelected(item);
     }
 }
