How to add the slider (left and right) effect using seekbar?

I have a dialog and in this i have 2 button "Yes" and "No". If i slide right then it will treat as pressed "No" and if i slide left it will treated as pressed "Yes" same as like some phone calling screes do for accept and reject calls. I tired this link. Initially my slider is positioned at mid position (android:progress ="50"), and if current progress returns 5 i am considering it pressed "yes" and if it returns 90 i consider pressed "No" and when i try to slide left or right it should produce a sliding effect for better UI as thumb moves. I tired this way but its not a good effect when right/left movement of thumb..
Means i want exactly same as slide to unlock button like this but want to keep the slider in middle so that i can move both side for Yes and No.

And my seekbar.xml looks like....
<SeekBar

android:layout_marginTop="10dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:progress="50"
android:progressDrawable="#drawable/seek_bar"
android:thumb="#drawable/slide_thumb"
android:splitTrack="false"
android:background="#null"
android:thumbOffset="2dp"
android:paddingLeft="2dp"
android:paddingRight="2dp"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Yes"
android:textSize="25sp"
android:textColor="#android:color/white"
android:layout_marginTop="22dp"
android:layout_marginLeft="10dp"
android:textStyle="bold"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="No"
android:textSize="25sp"
android:textColor="#android:color/white"
android:layout_alignParentRight="true"
android:layout_marginTop="22dp"
android:layout_marginRight="10dp"
android:textStyle="bold"
/>
but its not giving me the right effect as i wanted, i want same as these below pictures are.. But with "yes" and "No" text.

If you don't like the default thumb, you will have to create your own Drawable, which you can then set the thumb in code with something like:
Drawable thumb = getResources().getDrawable( R.drawable.myThumb );
SeekBar mSeekBar = (SeekBar) findViewById(R.id.mySeekBar);
mSeekbar.setThumb(thumb);
Or you can set the thumb in XML with:
<SeekBar
...
android:thumb="#drawable/seek_thumb" />
The actual Drawable can be an image, shape, or any other kind of Drawable you could possibly desire. If you want the thumb to change appearance when it is pressed, you will want to create a State List Drawable.

change background with animation when user clicks on it

I used one LinearLayout in my activity for changing two views. Here, i used two textviews. When user clicks on linear layout i change views as per my requirnments. xml file is here,
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:background="#drawable/customswitchselector"
android:textStyle="bold"
android:layout_below="#+id/linearTab"
android:layout_marginTop="20dp"
android:layout_marginBottom="20dp"
android:layout_marginLeft="30dp"
android:layout_marginRight="30dp"
android:showText="true"
android:id="#+id/switch1"
android:checked="false"
android:weightSum="2">
<TextView
android:id="#+id/tv_switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center_vertical"
android:layout_weight="1"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="5dp"
android:paddingBottom="5dp"
android:textStyle="bold"
android:textColor="#272351"
style="bold" />
<TextView
android:id="#+id/tv_switch_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_weight="1"
android:textStyle="bold"
android:layout_gravity="center_vertical"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="5dp"
android:paddingBottom="5dp"
android:textColor="#ffffff"
style="bold"
/>
</LinearLayout>
These two images show my two conditions. I have done enough to change this. Now i want to do animation while i am changing background for textviews on layout clicks. I have checked transitiondrawable example but it not helpful to me.
customswitchselector.xml
<?xml version="1.0" encoding="utf-8"?>

custom_track.xml This is used for textview with blue background
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:dither="true"
android:shape="rectangle"
android:useLevel="false"

<gradient
android:angle="270"
android:endColor="#292850"

<size

android:height="30dp" />
</shape>

A possibility would be to set the white drawable as background of a FrameLayout and add a View for the blue oval and two TextViews for the titles to it.
To still acchieve that the views takes exactly the half of the container you could use PercenFrameLayout (read more about it in the official docu). To use it you need to add this dependency to your build.gradle: compile 'com.android.support:percent:25.2.0'
After creating the layout you just animate the gravity of the blue oval from left to right or the other way round.
So your layout would look like this:
<PercentFrameLayout
android:id="#+id/container"
android:animateLayoutChanges="true"
android:background="#drawable/white_oval"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!-- blue oval -->
<View
android:id="#+id/blue_oval"
android:gravity="start"
android:background="#drawable/blue_oval"
app:layout_widthPercent="50%"
android:layout_height="wrap_content"
android:transformPivotX="0dp" />
<!--2 textviews-->
<TextView
app:layout_widthPercent="50%"
android:layout_height="wrap_content"
android:text="left"
android:gravity="start"/>
<TextView
app:layout_widthPercent="50%"
android:layout_height="wrap_content"
android:text="right"
android:gravity="end"/>
</FrameLayout>
Then in your code animate the gravity change of the blue oval like this:
private void animateGravity(int toGravity) {
LayoutTransition layoutTransition = container.getLayoutTransition();
layoutTransition.enableTransitionType(LayoutTransition.CHANGING);
layoutTransition.setDuration(YOUR_ANIMATION_DURATION);
layoutTransition.setInterpolator(LayoutTransition.CHANGING, new AccelerateDecelerateInterpolator());
FrameLayout.LayoutParams layoutParams = (LayoutParams) blueOvalView.getLayoutParams();
layoutParams.gravity = toGravity;
blueOvalView.setLayoutParams(layoutParams);
}

Thank in advance

Instead of button you can use this and implement click event of framelayout.
<FrameLayout
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="<Your Background image>">
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="<Your text>"
android:textSize="18sp" />
<ImageView
android:id="#+id/image"
android:layout_width="20dp"
android:layout_height="20dp"
android:layout_gravity="right|center"
android:layout_marginRight="10dp"
android:gravity="center|right"
android:src="<image drawable>" />
</FrameLayout>

Android: Round Image inside ring shape

I want to create a button with image inside it as shown at the bottom of this pic https://trianglewiki.org/RGreenway_App/_files/android.jpg/_info/. I am trying using layer-list and shape drawables and able to create buttons very similar. My problem is that my image is not scaling inside the button as I would like. The ring shape is coming on the top of the image but image is not inside it.
I want the image to be completely inside the ring. I think there is something wrong with the parameters values I am giving. But it could be I am not doing it the proper way.
Can somebody check my xml files and see what is the problem or provide me with any information how to do it so that I get the same effect in the button as in the link above. Thanks

You are overcomplicating this is if I understand your question. Look to here for an answer. It's the trick I have used in the past.
