本文实例分析了Android中ListView用法。分享给大家供大家参考，具体如下：
通过在Layout中添加ListView Widget可以达到在页面布局具有列表效果的交互页面。在这里通过举例来说明怎样在Layout中添加ListView以及怎样应用。
配合设计了两个事件Listener: OnItemSelectedListener事件为鼠标的滚轮转动时所选择的值；OnItemClickListener事件则为当鼠标单击时，所触发的事件。由此可以区别出list中的“选择”与“单击”差异。
使用ArrayAdapter(Context context, int textViewResourceId , T[] objects)这个构造器，其中textViewResourceId是定义在“res/layout/my_simple_list_item.xml”里的资源ResourceID(R.layout.my_simple_list_item),里面使用CheckedTextView来取得ListView中选择的项目。
程序中使用了LinearLayout对象，动态地将TextView与ListView附加进原有的Layout布局当中。用LinearLayout.LayoutParams来创建对象param1,再调用LinearLayout的addView方法将TextView和ListView以及params对象传入。
程序如下所示：

public class A07Activity extends Activity {
private static final String[]week="sunday","monday","tuesday","wednesday","thursday","friday","saturday"};
private TextView tv;
private ListView lv;
private ArrayAdapter<String> aa;
private LinearLayout ll;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
tv=new TextView(this);
tv.setText(R.string.title);
tv.setTextColor(Color.RED);
lv=new ListView(this);
lv.setBackgroundColor(Color.GREEN);
ll=new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
ll.setBackgroundColor(android.graphics.Color.YELLOW);
aa=new ArrayAdapter<String>(A07Activity.this,R.layout.my_simple_list,week);
lv.setAdapter(aa);
LinearLayout.LayoutParams params01=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
ll.addView(lv, params01);
LinearLayout.LayoutParams params02=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
ll.addView(tv, params02);
setContentView(ll);
lv.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
tv.setText("你选择的是："+arg0.getSelectedItem().toString());
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
tv.setText("你选择的是："+week[arg2]);
}
});
}
