从类中向listview添加数据 [英] Add data to listview from a class

问题描述

你好我有一个android项目。我有一个主要活动列表视图我想从课程中添加数据而不是来自这个主要活动的任何帮助吗？



什么我试过了：



String [] x = new String [] {AAA，BBB，CCC，DDD， EEE， FFF， GGG， HHH， III， JJJ， KKK， LLL， MMM， NNN， OOO， PPP，QQQ };

ListView lv =（ListView）findViewById（R.id.listView1）;

ArrayAdapter< string> test = new ArrayAdapter< string>（this，android.R.layout.simple_list_item_1，x）;

lv.setAdapter（test）;

这是来自我想要的mainactivity来自class

hello i have an android project.i have a mainactivity a listview i want to add data from class not from this mainactivity any help ?

What I have tried:

String[] x = new String[]{"AAA","BBB","CCC","DDD","EEE","FFF","GGG","HHH","III","JJJ","KKK","LLL","MMM","NNN","OOO","PPP","QQQ"};
ListView lv = (ListView) findViewById(R.id.listView1);
ArrayAdapter<string> test = new ArrayAdapter<string>(this, android.R.layout.simple_list_item_1,x);
lv.setAdapter(test);
this is from mainactivity i want from class
