Question

我的项目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添加了一些数据，然后单击对话框保存按钮现在我想在按钮点击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edittext（保存）值未在textview（tv）中设置 ????? .....

Answer 1

在布局文件夹中创建布局，并将其作为“查看对话框对象”提供。对于下面显示的示例，您需要在该布局中使用TextView，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();
