Android的 - 构建code动态表单 [英] Android - build dynamic form from code

问题描述

我在我的活动，以构建一个动态的形式取决于是从XML popullated通过HTTP检索到的数据。

I have to build a dynamic form in my activity depending on the data retrieved via HTTP that is popullated from XML.

这可能是一个或多个 RadioGroup中 s分别有整整三单选秒。之后RadioGroups我需要把两个的EditText 和一个复选框控制与事后提交按钮。

This could be one or more RadioGroups each with exactly three RadioButtons. After RadioGroups I need to place two EditText and one CheckBox control with submit button afterwards.

我有prepared一个的LinearLayout 垂直方向和唯一的ID从code解决，我希望我可以创建中的表单控件没有定义在Android的XML布局，并增加该Java code 的LinearLayout 。

I have prepared a LinearLayout with vertical orientation and unique ID to be addressed from code and I expect that I can create a form control within a Java code without defining in android XML layout and adding to this LinearLayout.

我在Google上搜寻了几个小时也没有找到任何例子，如何做到这一点。

I was googling for a few hours but could not find any example how to do this.

任何人都可以请提供一些例子，如何创建如一个 RadioGruop 1-2 单选和它添加到的LinearLayout （即prepared在XML布局）？

Could anyone please provide some example how to create e.g. one RadioGruop with 1-2 RadioButtons and add it to the LinearLayout (that is prepared in XML layout)?

非常感谢任何意见！

推荐答案

这些小工具可以创建一个像所有其他部件：

These widgets can be create like every other widgets:

final Context context; /* get Context from somewhere */
final LinearLayout layout = (LinearLayout)findViewById(R.id.your_layout);
final RadioGroup group = new RadioGroup(context);
final RadioButton button1 = new RadioButton(context);
button1.setId(button1_id); // this id can be generated as you like.
group.addView(button1,
    new RadioGroup.LayoutParams(
        RadioGroup.LayoutParams.WRAP_CONTENT,    
        RadioGroup.LayoutParams.WRAP_CONTENT));
final RadioButton button2 = new RadioButton(context);
button1.setId(button2_id); // this id can be generated as you like.
button2.setChecked(true);
group.addView(button2,
    new RadioGroup.LayoutParams(
        RadioGroup.LayoutParams.WRAP_CONTENT,    
        RadioGroup.LayoutParams.WRAP_CONTENT));
layout.addView(group,
    new LinearLayout.LayoutParams(
        LinearLayout.LayoutParams.MATCH_PARENT,    
        LinearLayout.LayoutParams.WRAP_CONTENT));

我没有测试此code，所以它可能包含一些错误。但我希望你明白了吧。

I haven't tested this code, so it may contain some errors. But I hope you'll get the idea.
