Android控制項之"ListView" @ 魚的方舟圖形語言的世界 - LabVIEW & Arduino & Python工作室 - 新網站https://labview-tech.blogspot.com/

ListView是Android中一種條列式顯示的控制項，

主要使用ListView與ArrayAdapter來顯示，

下列的程式為將要顯示的項目放入Array中，

然後將這一個Array放入ArrayAdpater，

之後再將listview.setAdapter方法，將 ArrayAdpater 放入，

1. Layout

2. Android code:

package com.example.codelistview;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.MenuItem;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class MainActivity extends Activity {
   private ListView listView;
   private String[] list = {"菜園","果園","動物園","海底樂園"};
    private ArrayAdapter<String> listAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        listView = (ListView)findViewById(R.id.listView1);
        listAdapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,list);
        listView.setAdapter(listAdapter);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
           @Override
           public void onItemClick(AdapterView<?> parent, View view, int position, long id){
               Toast.makeText(getApplicationContext(), "你點選的項目是" + list[position], Toast.LENGTH_SHORT).show();
           }
       });
    }
