伙计们,在onCreateDialog上我有这个：
case DIALOG_REVIEW: {
if (bundle.containsKey("POSITION")) {
final int position = bundle.getInt("POSITION");
ArrayList<String> alterNumbers = numbers.get(position);
final String[] phoneNums = new String[alterNumbers.size()];
for (int i = 0; i < alterNumbers.size(); i++) {
phoneNums[i] = alterNumbers.get(i);
}
AlertDialog.Builder dialog = new AlertDialog.Builder(this);
dialog.setTitle(names.get(position) + "'s number(s)");
dialog.setSingleChoiceItems(phoneNums,new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,int which) {
// get selected item and close the dialog
String selectedNumber = phoneNums[which];
updateUserSelectedNumber(position,selectedNumber);
}
});
return dialog.create();
}
这很有效.
但要注意线
dialog.setSingleChoiceItems(phoneNums,new DialogInterface.OnClickListener() {
假设每次弹出对话框时都会更改phoneNums.
我已经覆盖onPrepareDialog方法,但我不知道如何为它分配新值.
并且那里没有setSingleChoiceItems.
这是我的onPrepareDialog方法
case DIALOG_REVIEW: {
final int position = bundle.getInt("POSITION");
ArrayList<String> alterNumbers = numbers.get(position);
final String[] phoneNums = new String[alterNumbers.size()];
for (int i = 0; i < alterNumbers.size(); i++) {
phoneNums[i] = alterNumbers.get(i);
}
AlertDialog alertDialog = (AlertDialog) dialog;
alertDialog.setTitle(names.get(position) + "'s number(s)");
???
break;
}
解决办法是什么？
先谢谢你们.
解决方法
您需要使用AlertDialog类中的
getListView方法.然后在返回的对象上使用
setItemChecked方法.例：
alertDialog.getListView().setItemChecked(1,true);
