我有我的扩展 ListActivity 的 MainActivity 类,我将适配器设置为通过方法中的自定义适配器列出onResume()
。
@Override
protected void onResume()
{
super.onResume();
this.setListAdapter(null);
adapter=new ContactListAdapter(this, R.id.txvNNPersonId, helper.getContacts(sortByname));
setListAdapter(adapter);
}
处理列表项点击,我用这个
protected void onListItemClick(ListView l, View v, int position, long id)
{
RelativeLayout r=(RelativeLayout)v;
TextView txvPersonId=(TextView)r.getChildAt(0);
int iid=Integer.parseInt(txvPersonId.getText().toString());
Intent intent=new Intent(this,ViewContactActivity.class);
intent.putExtra("id", iid);
startActivityForResult(intent, VIEW_RECORD);
//these is not working, these event is not raised, when clicked on listitem click
}
但是当通过鼠标单击/触摸项目时它不起作用,它仅在我将它与选择并实现的项目一起使用时才起作用onItemSelectedListener
@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
RelativeLayout r=(RelativeLayout)arg1;
TextView txvPersonId=(TextView)r.getChildAt(0);
int id=Integer.parseInt(txvPersonId.getText().toString());
Intent intent=new Intent(this,ViewContactActivity.class);
intent.putExtra("id", id);
startActivityForResult(intent, VIEW_RECORD);
}
这仅适用于模拟器上的箭头键,但在真实设备上,(通常)它们没有箭头/导航键,如何定义列表项的单击?
编辑:row_item.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:longClickable="true"
android:orientation="horizontal">
<TextView android:id="@+id/txvPersonId"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:visibility="invisible" /> -->
<!-- this is name -->
<TextView android:id="@+id/txvPersonName"
android:layout_marginLeft="5dp"
android:layout_width="match_parent"
android:layout_height="40dp"
android:gravity="center_vertical"
android:text="asd"
android:textSize="15sp"
android:paddingBottom="5dp" />
</RelativeLayout>`
