我有一个通过ExpandableListView生成的AlertDialog。列表本身完美地工作，但出于某种原因，点击被忽略了。显然，我的点击处理程序从未被调用。
这是代码：
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select something");
ExpandableListView myList = new ExpandableListView(this);
MyExpandableListAdapter myAdapter = new MyExpandableListAdapter();
myList.setAdapter(myAdapter);
myList.setOnItemClickListener(new ExpandableListView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int i, long l) {
try {
Toast.makeText(ExpandableList1.this, "You clicked me", Toast.LENGTH_LONG).show();
}
catch(Exception e) {
System.out.println("something wrong here ");
}
}
});
builder.setView(myList);
dialog = builder.create();
dialog.show();
如果我尝试使用普通的列表视图填充AlertDialog，则可以生成点击事件，没有任何问题：
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select Color Mode");
ListView modeList = new ListView(this);
String[] stringArray = new String[] { "Bright Mode", "Normal Mode" };
ArrayAdapter<String> modeAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, stringArray);
modeList.setAdapter(modeAdapter);
modeList.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text
Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
Toast.LENGTH_SHORT).show();
}
});
builder.setView(modeList);
AlertDialog dialog1 = builder.create();
dialog1.show();
为什么在我的可扩展列表视图中点击事件失败，而在普通列表视图中却没有问题？我可能错过了什么，但我不知道具体是什么。
