1 How to create custom Textview with font type in Android

Tweet

Textview: “Displays text to the user and optionally allows them to edit it.”

In this tutorial, we show you how to create custom text view with some attributes.

This project is developed in Eclipse 4.2.0.

Here is a result of this tutorial:

1. Make some textviews by xml layout:

             <TextView android:id="@+id/textview1"

                    android:layout_width="fill_parent"

                     android:layout_height="wrap_content"

                     android:textSize="27px"

                     android:text="Hello Android"

                     android:gravity="center"

                     android:textColor="#343434" />

         

              <TextView android:id="@+id/textview2"

                     android:layout_width="fill_parent"

                     android:layout_height="wrap_content"

                     android:textSize="27px"

                     android:text="Custom textview"

                     android:gravity="center"

                     android:textColor="#CD2134" 

                     android:textStyle="bold"

                    android:shadowColor="#00ccff" 

                     android:shadowRadius="1.5" 

                    android:shadowDx="1" 

                    android:shadowDy="1" />

             

              <TextView android:id="@+id/textview3"

                    android:layout_width="fill_parent"

                     android:layout_height="wrap_content"

                     android:textSize="27px"

                     android:text="Nice Font type"

                     android:gravity="center"

                     android:textColor="#00ccff"

                     android:textStyle="italic"  />

The result is:

You can see some of attribute of these textviews

Text Style

The android:textStyle attribute can be used to put emphasis on text. The possible values are: normal, bold, italic. You can also specify bold|italic.

                                    android:textStyle="bold"

Text Size

android:textSize specifies the font size. Its value must consist of two parts: a floating-point number followed by a unit. Available units are: sp (scaled pixels), px (pixels), dp (density-independent pixels), in (inches), mm (millimeters). It is generally a good practice to use the sp unit so the size can scale depending on user settings.

android:textSize="27px"

Text Color                  

The android:textColor attribute’s value is a hexadecimal RGB value with an optional alpha channel, similar to what’s found in CSS and can be in one of the following formats:

android:textColor="#343434"

Text Shadow

android:shadowColor Shadow color in the same format as textColor.

android:shadowRadius Radius of the shadow specified as a floating point number.

android:shadowDx The shadow’s horizontal offset specified as a floating point number.

android:shadowDy The shadow’s vertical offset specified as a floating point number.

The floating point numbers don’t have a specific unit – they are merely arbitrary factors.

                                    android:shadowColor="#00ccff" 

                                    android:shadowRadius="2.5" 

                                    android:shadowDx="2" 

                                    android:shadowDy="2" /

2. Change the font type of textview by click on the button

The code to load and set the custom font is straight forward as well, and is shown below.

public void button_click(View view){ 

   Typeface face1=Typeface.createFromAsset(getAssets(), "fonts/d-puntillas-A-Lace.ttf");

   TextView txtView1=(TextView)findViewById(R.id.textview1);

   txtView1.setTypeface(face1);

       

   Typeface face2=Typeface.createFromAsset(getAssets(), "fonts/Chantelli_Antiqua.ttf");

   TextView txtView2=(TextView)findViewById(R.id.textview2);

   txtView2.setTypeface(face2);

       

   Typeface face3=Typeface.createFromAsset(getAssets(), "fonts/cinnamon cake.ttf");

   TextView txtView3=(TextView)findViewById(R.id.textview3);

    txtView3.setTypeface(face3);

}

This above codes have three new fonts to set for textviews, we have to take them in folder assets/fonts/ of our project. To do this, we create a fonts folder in our assets directory and copy our font there.

When you click on the button, all textview will change the font type
