在布局 xml 和 Java 中使用字符串资源

Question

I have one button view in my layout.xml like below

<Button
                            android:id="@+id/btn_follow"
                            android:layout_width="140dp"
                            android:layout_height="40dp"
                            android:layout_marginTop="15dp"
                            android:layout_marginBottom="15dp"
                            android:background="@{viewModel.isMyAccount == 1 ? @drawable/bg_grey_corner_5 : (viewModel.isMyAccount == 2 ? @drawable/bg_gradient : @drawable/bg_strock_corner_5)}"
                            android:fontFamily="@font/popins_light"
                            android:letterSpacing="0.05"
                            android:onClick="@{()->viewModel.setOnItemClick(1)}"
                            android:text='@{viewModel.isMyAccount == 1 ? "Unfollow" : (viewModel.isMyAccount == 2 ? "Follow" : "Edit Profile")}'
                            android:textAllCaps="false"
                            android:textColor="@color/light_white"
                            android:textSize="13sp"
                            android:textStyle="bold"
                            tools:text="Follow">

                        </Button>

It have used model condition for display text label in button like below

android:text='@{viewModel.isMyAccount == 1 ? "Unfollow" : (viewModel.isMyAccount == 2 ? "Follow" : "Edit Profile")}'

but I am trying to support multiple language in my app and so I want use string resource there along with java model condition, Let me know if someone have idea about do it, I am new and learning android yet. Thanks!

Answer 1

You can use:

android:text="@{condition ? @string/follow: @string/unfollow}

Answer 2

Instead of hard coding the follow and unfollow, retrieve them from string resources using then you can add additional string files for all the languages your app will support. So the system will default to English for example at all times but if the app is being used in other countries for example France and there is Fr resource then the system will grab that file and display the contents in French. But remember it's your responsibility to add French translation for all the strings used in your app.
