以编程方式将id添加到R.id [英] programmatically add id to R.id

问题描述

我正在创建一个EditText对象，然后尝试在单元测试中引用该对象.为该动态创建的对象向R.id添加新的id的最佳方法是什么，以便以后可以在单元测试中通过findViewById()引用它?

解决方案

您可以使用xml资源文件设置ID，以便稍后在R.id类中使用，并让Android SDK在编译时为其提供唯一值./p>

res/values/ids.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <item name="my_edit_text_1" type="id"/>
    <item name="my_button_1" type="id"/>
    <item name="my_time_picker_1" type="id"/>

</resources>

要在代码中使用它:

myEditTextView.setId(R.id.my_edit_text_1);

I am creating an EditText object which I then try to reference in a unit test. What is the best way to add a new id to R.id for this dynamically created object, so that I can later reference it via findViewById() in the unit test?

解决方案

You can set ID's you'll use later in R.id class using an xml resource file, and let Android SDK give them unique values during compile time.

res/values/ids.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <item name="my_edit_text_1" type="id"/>
    <item name="my_button_1" type="id"/>
    <item name="my_time_picker_1" type="id"/>

</resources>

To use it in code:

myEditTextView.setId(R.id.my_edit_text_1);
