设计整个程序是通过主界面的三个按钮跳转到三个界面,分别是用BaseAdapte,SimpleAdapter,ArrayAdatper显示ListView
主界面如下
点击任何一个按钮则跳转相应界面,三个界面差不多,只是id设置不同,其中一个界面如图:
现在给出全部布局文件代码:
activity_main
activity_simple
主界面:

super.onCreate(icicle);
setContentView(R.layout.activity_main);
Button button1 = (Button) findViewById(R.id.button1);
Button button2 = (Button) findViewById(R.id.button2);
Button button3 = (Button) findViewById(R.id.button3);
button1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(MainActivity.this,
BaseActivity.class);
startActivity(intent);
}
});
button2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
