ListView的应用
我们今天要讲的内容是Android中ListView中的实现.一共分为四个步骤,我将一一讲解:
Step one:创建一个新的Android工程,命名为ListViewDemo.
Step two:找到ListViewDemo.java,把我们习惯的继承Activity,改成ListActivity,如下:
public class ListViewDemo extends ListActivity
Step three:修改ListViewDemo.java代码方法如下:
package com.android.test;
import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
public class ListViewDemo extends ListActivity {
static final String[] COUNTRIES = new String[]{
"Americian","Belize","China","Japan","Korean","Russian"
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1
,COUNTRIES));
}
}
