Android动态创建ListView视图，动态增加和删除Item.

package com.example.mycustomview; import java.util.ArrayList;
import java.util.Arrays;
import java.util.List; import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast; public class MainActivity extends Activity {
ListView listView;
ArrayAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //新建数组
        String[] mylistdata={"Chinese","Japanese","American","Austrilian","Britisher","India","French","Chinese","Japanese","American","Austrilian","Britisher","India","French"};
        //注意：一定要将String[]转成List，否则不能动态增加和删除
        List list=new ArrayList<>(Arrays.asList(mylistdata));         //新增加adapter适配器
        adapter=new ArrayAdapter(this,android.R.layout.simple_list_item_1,list);         //创建ListView
        listView=new ListView(this);          //将adapter适配器置入ListView
        listView.setAdapter(adapter);         //设置默认布局为ListView
        setContentView(listView);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView parent, View view, int position, long id) {
        String item = adapter.getItem(position);
        adapter.remove(item);
        adapter.add(item+"   city");
        Toast.makeText(MainActivity.this, item.toString(), Toast.LENGTH_SHORT).show();
        }
        });     }
}
