Android studio use spannablestring in file new file
To use a SpannableString
in a new file in Android Studio, you can follow these steps:
- Create a new file: Go to
File
>New
>File
and chooseText File
as the file type. - Name the file: Name the file with a
.java
extension, for example,MySpannableString.java
. - Import the necessary classes: At the top of the file, add the following import statements:
import android.text.SpannableString; import android.text.style.StyleSpan; import android.text.style.UnderlineSpan;
- Create a
SpannableString
object: Create aSpannableString
object and assign it to a variable, for example:SpannableString spannableString = new SpannableString("Hello, World!");
- Add spans to the
SpannableString
: Use thesetSpan()
method to add spans to theSpannableString
. For example, to underline the text, you can use theUnderlineSpan
class:spannableString.setSpan(new UnderlineSpan(), 0, 7, 0);
- Use the
SpannableString
in your code: You can use theSpannableString
object in your code, for example, to display it in aTextView
:TextView textView = findViewById(R.id.my_text_view); textView.setText(spannableString);
Here's the complete code:
import android.text.SpannableString; import android.text.style.StyleSpan; import android.text.style.UnderlineSpan;
public class MySpannableString { public static void main(String[] args) { SpannableString spannableString = new SpannableString("Hello, World!"); spannableString.setSpan(new UnderlineSpan(), 0, 7, 0); TextView textView = findViewById(R.id.my_text_view); textView.setText(spannableString); } }
Note that in this example, we're using the `main()` method, which is not typically used in Android apps. In a real Android app, you would use the `SpannableString` object in a `TextView` or other widget, and not in a `main()` method.
