Set style for TextView programmatically

Question

I\'m trying to use the TextView constructor with style like this:

TextView myText = new TextView(MyActivity.this, null, R.style.my_style);


        

Answer 1

The accepted answer was great solution for me. The only thing to add is about inflate() method.

In accepted answer all android:layout_* parameters will not be applied.

The reason is no way to adjust it, cause null was passed as ViewGroup parent.

You can use it like this:

View view = inflater.inflate(R.layout.view, parent, false);

and the parent is the ViewGroup, from where you like to adjust android:layout_*.

In this case, all relative properties will be set.

Hope it'll be useful for someone.

Answer 2

I have only tested with EditText but you can use the method

public void setBackgroundResource (int resid)

to apply a style defined in an XML file.

Sine this method belongs to View I believe it will work with any UI element.

Answer 3

You can pass a ContextThemeWrapper to the constructor like this:

TextView myText = new TextView(new ContextThemeWrapper(MyActivity.this, R.style.my_style));

Answer 4

You can set the style in the constructor (but styles can not be dynamically changed/set).

View(Context, AttributeSet, int) (the int is an attribute in the current theme that contains a reference to a style)

Answer 5

Dynamically changing styles is not supported (yet). You have to set the style before the view gets created, via XML.

Answer 6

You can create a generic style and re-use it on multiple textviews like the one below:

textView.setTextAppearance(this, R.style.MyTextStyle);

Edit: this refers to Context
