在片段上显示对话框

Question

我必须在片段中显示一个对话框。 DialogFragment的代码是：

public class DialogSintesi extends DialogFragment {

private TextView brownModelli;
private TextView brownArticoli;
private TextView blankModelli;
private TextView blankArticoli;
private TextView pedModelli;
private TextView pedArticoli;

public DialogSintesi() {

}

public static DialogFragment newInstance(String title) {
    DialogFragment fragment = new DialogFragment();
    Bundle args = new Bundle();
    args.putString("title", title);
    fragment.setArguments(args);
    return fragment;
}

@Override    
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.popup_campagne_salvate, container);

    TextView brownModelli = (TextView) view.findViewById(R.id.textBrownModelliNumero);
    TextView brownArticoli = (TextView) view.findViewById(R.id.textBrownArticoliNumero);
    TextView blankModelli = (TextView) view.findViewById(R.id.textBlankModelliNumero);
    TextView blankArticoli = (TextView) view.findViewById(R.id.textBlankArticoliNumero);
    TextView pedModelli = (TextView) view.findViewById(R.id.textPedModelliNumero);
    TextView pedArticoli = (TextView) view.findViewById(R.id.textPedArticoliNumero);

    getDialog().setTitle("Sintesi Campagna");

    return view;
}

}

我尝试将对话框显示到自定义数组适配器中（在列表视图中按下按钮）

info.setOnClickListener(new View.OnClickListener(){

        @Override
        public void onClick(View arg0) {

            showDialogSintesi();
        }

    });

而showDialogSintesi的方法是：

public void showDialogSintesi(String nome) {
    android.app.FragmentManager fm = fragment.getFragmentManager();
    DialogFragment dialog = DialogSintesi.newInstance("Info");
    dialog.show(fm,"");

}

我尝试显示此对话框，但它有很多小时都不起作用！ 对不起我的英语不好。 太棒了

Answer 1

检查你是否在使用 android.support.v4.app 或 android.app 在您的代码中一致地导入和声明片段相关变量。

Answer 2

尝试用 onCreateDialog 替换 onCreateView：

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    View view = ((LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(
            R.layout.popup_campagne_salvate, container);

    TextView brownModelli = (TextView) view.findViewById(R.id.textBrownModelliNumero);
    TextView brownArticoli = (TextView) view.findViewById(R.id.textBrownArticoliNumero);
    TextView blankModelli = (TextView) view.findViewById(R.id.textBlankModelliNumero);
    TextView blankArticoli = (TextView) view.findViewById(R.id.textBlankArticoliNumero);
    TextView pedModelli = (TextView) view.findViewById(R.id.textPedModelliNumero);
    TextView pedArticoli = (TextView) view.findViewById(R.id.textPedArticoliNumero);

    builder.setView(view);
    builder.setTitle("Sintesi Campagna");

    Dialog dlg = builder.create();
    return dlg;
}

其余的应该和你一样。 您可以在此过程中填充 TextView。
