Android TextView with custom fonts

While developing an android app I found that everytime I was trying to use a custom font on a TextView I copied the same lines:
 
 
 
 
 
 
 
 
 

TextView textview = (TextView) findViewById(R.id.text);
textview.setTypeface(...)

Obviously, that’s unnecessary and repetitive. Why not just create a custom view? And more, why not adding the font through xml code?

public class CustomTextView extends TextView {

  private Context mContext;
	private String mFont;
	
	public CustomTextView(Context context) {
		super(context, null);
		mContext = context;
		init();
	}

	public CustomTextView(Context context, AttributeSet attrs) {
		super(context, attrs);
		mContext = context;
		TypedArray a = context.getTheme().obtainStyledAttributes(
		        attrs,
		        R.styleable.CustomButtom,
		        0, 0);
		try {
			mFont = a.getString(R.styleable.CustomButtom_font);
		} finally {
			a.recycle();
		}
		init();
	}
	
	private void init() {
		if (mFont != null) {
			setTypeface(FontsUtils.get(mFont));
		}
	}

}

We just have to extend from TextView and read from the attribute set the font string declared on its styleable resource. Just create an attrs.xml (or use an existing one) and add the following:

<declare-styleable name="CustomTextview">
  <attr name="font" format="string" />
</declare-styleable>

Now, you could declare on your xml layout like this:

<LinearLayout
  android:id="@+id/comments"
  android:layout_width="match_parent"
  android:layout_height="wrap_content" >
 
  <com.parkuik.android.ui.CustomTextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/no_comments" />
</LinearLayout>

  1. You didn’t include your FontsUtils() class in which, I assume, you’re actually doing the Typeface.createFromAsset() call to get the font from fonts/font_name.*tf

  2. Could you post your FontsUtils class please ?

  3. from where did we get “CustomButtom_font” ?

    thank you
