活动类代码:
conversationList = (ListView)findViewById(android.R.id.list);
ConversationArrayAdapter conversationArrayAdapter=new ConversationArrayAdapter(this, R.layout.conversation_list_item_format_left, conversationDetails);
conversationList.setAdapter(conversationArrayAdapter);
conversationList.setOnItemClickListener(new AdapterView.OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
Log.d("test","clicked");
}
});
Adapter类中的getView函数:
if (v == null) {
LayoutInflater vi = (LayoutInflater)ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if(leftSideMessageNumber.equals(m.getTo())) {
v = vi.inflate(R.layout.conversation_list_item_format_left, null);
} else {
v = vi.inflate(R.layout.conversation_list_item_format_right, null);
}
}
在膨胀时使用两个xml会有问题吗?
两个很棒的解决方案是，如果你从一个片段扩展ListFragment，知道mListView。setOnItemClickListener不会在你的活动创建之前被调用，这确保了它是在活动创建时设置的
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long rowId) {
// Do the onItemClick action
Log.d("ROWSELECT", "" + rowId);
}
});
}
在查看ListFragment的源代码时，我发现了这个
public class ListFragment extends Fragment {
...........................................
................................................
final private AdapterView.OnItemClickListener mOnClickListener
= new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
onListItemClick((ListView)parent, v, position, id);
}
};
................................................................
................................................................
public void onListItemClick(ListView l, View v, int position, long id) {
}
}
附加了一个onItemClickListener对象，它调用onListItemClick()
因此，其他类似的解决方案，以完全相同的方式工作是重写onListItemClick()
@Override
public void onListItemClick(ListView l, View v, int position, long rowId) {
super.onListItemClick(l, v, position, id);
// Do the onItemClick action
Log.d("ROWSELECT", "" + rowId);
}
