Question

我需要帮助将数据从父活动传递到对话框。我想在longclick上设置文本。

    public boolean onLongClick(View v) {
    RememberLongPressedButton(v);
    String buttonText = GetButtonText(v);
    DialogFragment newFragment = new SomeDialogFragment();
    newFragment.show(getFragmentManager(), _APPNAME);

    if(!(buttonText.equals(" ") || buttonText.isEmpty()))
        DataToEditText(newFragment,buttonText);

    return true;
}

Dialog片段类的代码

public class SomeDialogFragment extends DialogFragment {

public interface SomeDialogFragment {
    void onDialogPositiveClick(DialogFragment dialog);
    void onDialogNegativeClick(DialogFragment dialog);
}

private SomeDialogFragmentListener _listener;

@Override
public void onAttach(Context context) {
    super.onAttach(context);

        try {
            if(context instanceof SomeDialogFragmentListener)
                _listener = (SomeDialogFragmentListener) context;
        } catch (ClassCastException e) {
            // The activity doesn't implement the interface, throw exception
            throw new ClassCastException(context.toString()
                    + " must implement SomeDialogFragmentListener");

        }
}

当我拨打此线路时，我的应用程序崩溃了

        Dialog dialog = dialogFragment.getDialog();
    EditText editText = (EditText) dialog.findViewById(R.id.dialog_text);
