How to use two different font sizes for button text in Android?

问题

How could I implement a button background for ImageButton or Button which contains 2 textview each using different font sizes ? I cant use static images as background and I need to achieve this either using xml or programmatically.

This is a numeric keypad and it carries a numeric value and a set of alphabets each of which uses different font sizes and needs to be set as button text.

Here are some of the suggestions that pop-up on my brain but seems to have limitations since I want to reuse the UI component and avoid code repetition.

1. Create a layout xml containing 2 textfields and set that as background on the button. But how can I get a reference of these textview fields to set the value on them in the MyActivity.java?

2. Use a layeredlist ? still same problem reference of textviews

3. Or create a custom view and inflate layout mentioned in step 1. This solution resolves my problem.

Does any other solution exist for this UI requirement?

Thanks.

Hopefully this will help. This off course is not the only solution but it is a pretty simple one. Add the xml part in your xml instead of the button.

XML

<LinearLayout
    android:id="@+id/button_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20sp" 
        android:text="5"/>
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="12sp" 
        android:text="ABC"/>

</LinearLayout>

CODE

    LinearLayout button= (LinearLayout)findViewById(R.id.button_layout);
    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO DO whatever you want to do here

        }
    });

For your button you can use code like this

don't forget put font in your Assets folder

 Button btnA=(Button) findViewById(R.id.button1);
 Typeface typeface = Typeface.createFromAsset(getAssets(), "yourFont.ttf");
 btnA.setText("my custom font");
 btnA.setTypeface(typeface);
 btnA.setTextSize(20);//as per your size

and for more reference see this

do as your second button if this helps let me know thanks...
