hardcoded string “Button”, should use @string resource

I am new in Android app development and using Java language. My problem is every time I make a TextView or Button there is a triangle with the exclamation mark below them. and when I click it I saw a message saying:

hardcoded string “Button”, should use @string resource

I have two activities, in my main activity there is a Button that when you click it you will go in second activity. But when I go to my main.java to make a code for the button. There's always the above shown error. I think the eclipse can't find the id of my button and same for my TextView they have same error message.

Here is the code I made:

Button b = FindViewById(R.id.button1);

I also add:

Button b = (Button) FindViewById(R.id.button1);

I am using the latest eclipse classic and ADT august issue. The platform is Android 4.1 API 16.

In Android Studio, make changes to the String.xml and activity_main.xml files.

In this example you must create a text string in the strings.xml file. strings.xml

And in the activity_main.xml file, you should find the text of the string created, as shown in the example image. Save everything and the error disappears. activity_main.xml

I am a newbie too, but I believe I got this. So basically what's happening here, java wants you to put your hardcodes in string.xml. so that when accessing it, you will use the given methods below before:

Before.

But this is how it should be. Let's start by string.xml

create the same element like this in string.xml

Then come back to your activity_main.xml

Reference the created element this way

Main.xml file (The xml file which relates to the main activity)

Notice the id of the button, which is rounded in red. You have to use this id when you want to call it in a method, for an example

Button b = (Button) FindViewById(R.id.button1);

Furthermore, check whether your graphical layout matches with the image I have provided.

Graphical view of the Main.xml file

Just try your code again with these changes. Your main.java would look like this.

Main.java file

You shouldn't hardcode the "text" on the widgets use the strings resources ie., strings in the strings.xml to set the text. Declare the "text" you want to display as a string in strings.xml and access it using @string/your_string_name in the layout file.
