我有这个RadioPickerDialog:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_radio_buttons, null);
ButterKnife.bind(this, view);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
TextView tvTitle = view.findViewById(R.id.dialog_radio_title);
tvTitle.setText(title);
builder.setView(view)
.setPositiveButton(R.string.btn_ok, (DialogInterface.OnClickListener) (dialog, which) -> {
listener.onPickerConfirmClicked(getSelectedIndex());
dialog.dismiss();
})
.setNegativeButton(R.string.btn_cancel, (DialogInterface.OnClickListener) (dialog, which) -> {
dialog.dismiss();
});
for (int i = 0; i < items.size(); i++) {
RadioButton radioButton = new RadioButton(getActivity());
T item = items.get(i);
radioButton.setText(item.toString());
radioGroup.addView(radioButton);
}
RadioButton buttonCheckedByDefault = (RadioButton) radioGroup.getChildAt(defItemNum);
buttonCheckedByDefault.setChecked(true);
return builder.create();
}
对话框调用:
UiUtils.showRadioButtonPickerDialog(this, reasonList, getString(R.string.workshift_pause), 0, new RadioButtonPickerDialog.PickerListener() {
@Override
public void onPickerConfirmClicked(int selectedIndex) {
presenter.setPause(reasonList.get(selectedIndex), true);
}
}
);
我要处理未单击事件(在非对话框中单击或单击取消按钮)。我该怎么办?

我找到了解决方法:
....
//When clicked negativeButton
@Override
public void onCancel(DialogInterface dialog){
dialog.dismiss();
}
//when clicked not in the dialog box
@Override
public void onDismiss(DialogInterface dialog){
dialog.dismiss();
}

只需将监听器添加到关闭事件即可,例如通过setOnDismissListener()
方法。最好在此方法内调用某种外部类级别的回调,以将工作委托给调用者(片段/活动,显示此对话框),这样您将始终引用当前显示的片段,万一您可能需要显示多个。
