我正在开发一个应用程序,我在其中以编程方式创建一个 Edittext:
I am developing an application in which i am creating an Edittext programmatically as :
EditText edText = new EditText(this);
edText.setId(1);
edText .setLayoutParams(new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,0f));
edText .setInputType(InputType.TYPE_CLASS_NUMBER);
edText.setHint("dsgsdgsgs");
tableLayout.addView(edText);
在这里,我通过 edText.setId(1);
行将编辑文本的 id 设置为1",以整数表示.
Here I am setting the id of the Edit text as "1" by the line edText.setId(1);
in integer.
但我需要的是 - 我想以字符设置 ID,例如:
But what i need is - I want to set the ID in character as for example:
edText.setId("edittext_hello");
这样我就可以通过该 ID 访问它.我怎样才能完成这项任务,请帮忙.
So that i can access it via that id. How can i achieve this task please help.
不能将 id 设置为 String.您只能将整数分配为 Id.但是,如果您想使用 String 作为 id 以便于使用,那么 -在 res/values/ids.xml 文件中
You can't set id as a String. You can only assign integer as Id. But if you want to use String as id for the ease of use then - in res/values/ids.xml file
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item name="edit_text_hello" type="id"/>
</resources>
然后将其用作:
edText.setId(R.id.edit_text_hello);
所以你可以做你需要的.
So you can do what you need.
