onClick事件后，创建一个对话框 [英] Creating a Dialog after an onClick event

问题描述

你好我工作的第一次与对话。 我想创建一个对话框，在列表视图中的项目被点击后：

Hi i am working the first time with dialogs. i want to create a dialog after an item in a listView was clicked:

    String[] listItems = {"Colour", "Font Size",};
    ListView lv = (ListView) findViewById(R.id.settings_list);

    lv.setAdapter(new ArrayAdapter<String>
    (this, android.R.layout.simple_list_item_1, listItems));

    lv.setOnItemClickListener(new OnItemClickListener()
    {
        public void onItemClick(AdapterView<?> parent, View
                view, int position, long id)
        {
            String[] listItems = {"Colour", "Font Size",};
            if(listItems[position].equals("Font Size"))
            {


                    public dialog onCreateDialog(Bundle savedInstanceState)
                    {
                        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
                        builder.setTitle("Choose Font Size");
                    }



            }

        }
    });

我得到在onCreateDialog一个错误（包savedInstanceState） Eclipse的想要一个;周围捆绑savedInstanceState，但developer.android说，否则。 任何提示？

I get an error at onCreateDialog(Bundle savedInstanceState) Eclipse wants a ; around Bundle savedInstanceState, but developer.android says otherwise. Any tips?

推荐答案

调用这个方法在你的onItemClick方式：

Call this method in your onItemClick method :

 public void showMyCustomDialog(Context context, String title, String message)
    {
        final Dialog dialog = new Dialog(context);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        //tell the Dialog to use the customalertdialog.xml as it's layout description
        dialog.setContentView(R.layout.customalertdialog);
        TextView titleText = (TextView) dialog.findViewById(R.id.txtTitleAlertDialog);
        titleText.setText(title);
        TextView txt = (TextView) dialog.findViewById(R.id.txtAlertDialog);
        txt.setText(message);
        Button dialogButton = (Button) dialog.findViewById(R.id.buttonAlertDialogCancel);
        dialogButton.setText("OK");
        dialogButton.setOnClickListener(new View.OnClickListener() 
        {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        dialog.show();
    }

喜欢的东西如下：

Something like below :

lv.setOnItemClickListener(new OnItemClickListener()
    {
        public void onItemClick(AdapterView<?> parent, View
                view, int position, long id)
        {
            String[] listItems = {"Colour", "Font Size",};
            if(listItems[position].equals("Font Size"))
            {
                    public dialog onCreateDialog(Bundle savedInstanceState)
                    {
                        showMyCustomDialog(Context context, String title, String message) // pass title, message and activity context in this method.
                    }
            }
        }
    });

希望这将有助于。
