从android中的自定义对话框edittext中获取值

Question

我的项目在我的屏幕上有一个文本视图和按钮。在按钮单击事件上，我显示自定义对话框（对话框内容编辑文本和按钮）。我在对话框编辑文本中放入了一些数据，然后单击对话框保存按钮。
现在我想在单击按钮时在屏幕文本视图上显示对话框编辑文本的值。我怎样才能做到这一点.... holder.list1.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                final TextView tv=(TextView)v.findViewById(R.id.textView3);
                final Dialog dialog = new Dialog(activity);
                dialog.setContentView(R.layout.customdailogfroaddmilk);
                dialog.setTitle("Account");

                // set the custom dialog components - text, image and button
                final EditText text = (EditText) dialog.findViewById(R.id.editText1);
                text.setText(tv.getText().toString());


                Button save = (Button) dialog.findViewById(R.id.button1);
                Button cancle = (Button) dialog.findViewById(R.id.button2);
                save.setOnClickListener(new OnClickListener() {
                    public void onClick(View v) {

                        dialog.dismiss();
                        tv.setText(text.getText().toString());
                    }
                });

                cancle.setOnClickListener(new OnClickListener() {
                    public void onClick(View v) {
                        dialog.dismiss();
                    }
                });

                dialog.show();
            }
        });

按钮（保存）单击事件编辑文本（保存）值未在 textview(tv) 中设置 ?????.....

Answer 1

在您的布局文件夹中创建一个布局，并将其作为视图提供给一个对话框对象。 对于下面显示的示例，您需要在该布局中有一个 TextView、一个 Button 和 EditText。

        final Dialog dialog = new Dialog(context,
                        android.R.style.Theme_Translucent_NoTitleBar);
        Window window = dialog.getWindow();
        window.setLayout(ViewGroup.LayoutParams.FILL_PARENT,
                        ViewGroup.LayoutParams.FILL_PARENT);
        dialog.setCancelable(true);
        dialog.setCanceledOnTouchOutside(true);
        dialog.setContentView(R.layout.xmlfile);

        Button ok = (Button) dialog.findViewById(R.id.alert_ok_button);
        TextView  alert_title = (TextView ) dialog.findViewById(R.id.alert_title);
        final EditText shelf_name_edit=(EditText)dialog.findViewById(R.id.shelf_name_edit_area);

        alert_title.setText(title);
        alert_title.setTextSize(20);
        ok.setText("OK");
        ok.setTextSize(20);

        ok.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                dialog.cancel();
                Log.i("EditText Value",shelf_name_edit.getEditableText().toString());
            }

        });
        dialog.show();
