Answer 1

Use the selector XML tag to help you achieve this. Here, see this link about StateListDrawables. So their example shows

a button.xml file:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
    <item android:state_pressed="true"
      android:drawable="@drawable/button_pressed" /> <!-- pressed -->
    <item android:state_focused="true"
      android:drawable="@drawable/button_focused" /> <!-- focused -->
    <item android:drawable="@drawable/button_normal" /> <!-- default -->
</selector>

and then links an actual button to that xml:

<Button
  android:layout_height="wrap_content"
  android:layout_width="wrap_content"
  android:background="@drawable/button" />

Sergey Glotov and wheaties thanks for your help

For every ImageButton I create separate selectors for default and pressed state, I create ImageButton in xml:

                   <ImageButton
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:background="@drawable/month_button"
                    android:id="@+id/btnMonth"
                    android:onClick=ButonMonthClick"/>

And onClick event for all ImageButton I change background image programmatically:

        btnWeek.setBackgroundResource(R.drawable.week_pressed);
    btnMonth.setBackgroundResource(R.drawable.month_default);

Thant solve my problem!
