我有一个AlertDialog
,它将数组显示在一个选定的选项中:
protected boolean blFrom, blTo;
protected void showSelectToDialog() {
boolean[] checkedDate = new boolean[toDate.length];
int count = toDate.length;
DialogInterface.OnClickListener setD2 = new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//TODO Auto-generated method stub
onChangeSelectedTo(which);
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Select To Year");
builder.setSingleChoiceItems(toDate, count, setD2);
builder.setCancelable(true);
builder.setPositiveButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.dismiss();
}
});
dialog2 = builder.create();
dialog2.show();
}
protected void onChangeSelectedTo(int j) {
bTo.setText(toDate[j]);
sTo = ((AlertDialog)dialog2).getListView().getCheckedItemPosition();
blTo = true;
displayToast(String.valueOf(sTo));
to = j;
dialog.dismiss();
}
我想要做的是第一次加载它应该显示默认值。一旦我选择了一个选项并且对话框关闭并再次显示相同的对话框,它应该显示我之前选择的选项并滚动到它。
我如何完成它?
截至目前,我可以获得所选位置,但下一步是什么?
