I want to concat two strings for a TextView in android, Data Binding Api

Question

Im using DataBinding Api for setting the views in android layouts. Here is my layout.

layout.xml

Answer 1

concate it with grave accent (`)

android:text="@{`Hello ` + user.firstName}"/>

You can concat it in multiple ways, check it here concat-two-strings-in-textview-using-databinding

Answer 2

In case of static string and other dynamic you can use this

android:text="@{`Hello ` + user.firstName}"/>

In case of dynamic data you can use this.

android:text='@{user.firstName+" "+user.lastName}'

Answer 3

if you want to concat String resource with data from your model, you can do it in such way:

 android:text='@{@string/release_date+model.release_date}'

Answer 4

The simplest way I found to be is to replace ''(single) in place of ""(double), For Eg. You have two variables,

<variable name="a" type="String" />
<variable name="b" type="String" />

Now to concatenate,

android:text='a + " " + b}'
