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?
您需要在listview_item.xml中执行2步
设置根布局:android:descendantFocusability="blocksDescendants"
在这个项目中设置任何可聚焦或可点击的视图:
android:点击= " false "
android: focusable = " false "
android: focusableInTouchMode = " false "
下面是一个例子:listview_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="10dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:gravity="center_vertical"
android:orientation="vertical"
android:descendantFocusability="blocksDescendants">
<RadioButton
android:id="@+id/script_name_radio_btn"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textStyle="bold"
android:textColor="#000"
android:padding="5dp"
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
/>
</LinearLayout>
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);
}
