Button background not changing when keeping it pressed

I have the following xml in drawable.

<?xml version="1.0" encoding="utf-8"?>
<!--drawable/btn_send_comment.xml-->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <layer-list>
            <item android:bottom="0dp" android:left="2dp" android:right="0dp" android:top="2dp">
                <shape android:shape="rectangle">
                    <solid android:color="@color/fab_color_shadow"/>
                    <corners android:radius="2dp"/>
                </shape>
            </item>

            <item android:bottom="1dp" android:left="1dp" android:right="1dp" android:top="1dp">
                <shape android:shape="rectangle">
                    <solid android:color="@color/btn_send_normal"/>
                    <corners android:radius="2dp"/>
                </shape>
            </item>
        </layer-list>
    </item>
    <item android:state_pressed="true">
        <shape android:bottom="0dp" android:left="2dp" android:right="0dp" android:shape="rectangle" android:top="2dp">
            <solid android:color="@color/btn_default_light_normal"/>
            <corners android:radius="2dp"/>
        </shape>
    </item>

</selector>

I have the following code to change the state of the button to pressed:

package com.example.android.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.ViewAnimator;

import com.example.android.R;


public class SearchPeopleButton extends ViewAnimator implements View.OnClickListener {
    public static final int STATE_SELECTED = 0;
    public static final int STATE_NOT_SELECTED = 1;

Context ctx;
private static final long RESET_STATE_DELAY_MILLIS = 2000;

private int currentState;

private OnSendClickListener onSendClickListener;

private Runnable revertStateRunnable = new Runnable() {
    @Override
    public void run() {
        setCurrentState(STATE_SELECTED);
    }
};

public SearchPeopleButton(Context context) {
    super(context);
    init();
}

public SearchPeopleButton(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
}

private void init() {
    LayoutInflater.from(getContext()).inflate(R.layout.view_search_button, this, true);
    ctx = getContext();
}

@Override
protected void onAttachedToWindow() {
    super.onAttachedToWindow();
    currentState = STATE_SELECTED;
    super.setOnClickListener(this);
}

@Override
protected void onDetachedFromWindow() {
    removeCallbacks(revertStateRunnable);
    super.onDetachedFromWindow();
}

public void setCurrentState(int state) {

    currentState = state;
    if (state == STATE_NOT_SELECTED) {

    } else if (state == STATE_SELECTED) {
        setPressed(true);
    }
    showNext();
}

@Override
public void onClick(View v) {
    if (onSendClickListener != null) {
        onSendClickListener.onSendClickListener(this);
    }
}

public void setOnSendClickListener(OnSendClickListener onSendClickListener) {
    this.onSendClickListener = onSendClickListener;
}

@Override
public void setOnClickListener(OnClickListener l) {
    //Do nothing, you have you own onClickListener implementation (OnSendClickListener)
}

public interface OnSendClickListener {
    public void onSendClickListener(View v);
}

}

Here is the button usage in my view:

        <com.example.android.view.SearchPeopleButton
        android:id="@+id/btnPeople"
        android:layout_width="72dp"
        android:layout_height="match_parent"
        android:layout_marginBottom="2dp"
        android:layout_marginLeft="8dp"
        android:background="@drawable/btn_send_comment"
        android:elevation="4dp"
        android:orientation="vertical"/>

Here is my view_search_button.xml

    <?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">

    <ImageView
        android:id="@+id/ivFeedAvatar"
        android:src="@drawable/ic_hashtag_grey"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</merge>

I can see that I am getting onClickEvents but still the color of the pressed state is not showing up.

You can use an ImageButton control to display the image and support the pressed state. http://developer.android.com/reference/android/widget/ImageButton.html

Change your button usage to:

<ImageButton
    android:id="@+id/btnPeople"
    android:layout_width="72dp"
    android:layout_height="match_parent"
    android:layout_marginBottom="2dp"
    android:layout_marginLeft="8dp"
    android:background="@drawable/btn_send_comment"
    android:elevation="4dp"
    android:orientation="vertical"/>

You may also need to change your background xml drawable to include the proper images in both the pressed and unpressed states, depending on what you want to accomplish.
