简单的ArrayAdapter
最后更新于：2022-04-01 14:43:05
如果只是单纯显示文字的话，ArrayAdapter是一个不错的选择。不用像之前的BaseAdapter那样写这么多东西。不过我还是习惯用BaseAdapter啊
~~~
package com.example.mylistview;
import java.util.Random;
import java.util.Vector;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.BaseAdapter;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;
public class MainActivity extends Activity {
private ListView lv;
private Random rd;
private Vector arr;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.lv);
rd = new Random();
arr = new Vector();
for ( int i = 0 ; i < 50 ; i ++ ) {
arr.add(String.valueOf(rd.nextInt(5000)));
}
lv.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.item_text,arr));
}
}
