Custom Fonts and Custom Textview on Android

The constructor of TextView calls setTypeface(Typeface tf, int style) with the style parameter retrieved from the XML attribute android:textStyle. So, if you want to intercept this call to force your own typeface you can override this method as follow:

public void setTypeface(Typeface tf, int style) {    Typeface normalTypeface = Typeface.createFromAsset(getContext().getAssets(), "font/your_normal_font.ttf");    Typeface boldTypeface = Typeface.createFromAsset(getContext().getAssets(), "font/your_bold_font.ttf");    if (style == Typeface.BOLD) {        super.setTypeface(boldTypeface/*, -1*/);    } else {        super.setTypeface(normalTypeface/*, -1*/);    }}

You can use my CustomTextView which allows you to specify a font file name in your assets folder:

and the usage is really simple:

<com.my.app.CustomTextView        xmlns:custom="http://schemas.android.com/apk/res/com.my.app"                    android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="Test text"        android:id="@+id/testcustomview"         custom:fontAssetName="Politica XT.otf"        />

I think it's better to create your own package for custom fonts and import them in your project so that you can use them later in future

  package com.codeslips.utilities;    import android.content.Context;   import android.graphics.Typeface;  import android.util.AttributeSet;  import android.widget.TextView;    public class CustomTextView extends TextView {            public CustomTextView(Context context)               { super(context); setFont(); }            public CustomTextView(Context context,AttributeSet set)             { super(context,set); setFont(); }           public CustomTextView(Context context,AttributeSet set,int defaultStyle)              { super(context,set,defaultStyle); setFont(); }           private void setFont() {            Typeface typeface=Typeface.createFromAsset(getContext().getAssets(),"fonts/your-font.ttf");            setTypeface(typeface); //function used to set font             }            }

Now use the above class in your XML file to have your custom font

    <com.codeslips.utilities.CustomTextView          android:layout_width="wrap_content"        android:layout_height="match_parent"       android:text="Upload Image"        android:paddingTop="10sp"       android:textSize="14sp"       android:layout_weight="0.7"       android:textColor="@android:color/white"/>
