SlidingPanelLayout not work well from right to left in android

问题

I am creating SlidingPanelLayout from right to left for the filter purpose.The panel work fine it come out from right side and does animation but when Animation is stop it directly go to left side full but I want the ratio is 70% means right side panel came out 70% of the total screen and when click again it goes to hind and full Activity is display.

When first time Animation is stop the side panel goes to left side in the screenshot .But I want it right side.

ScreenShot :

but i want to display it write side and when click again it will go right side and hide again.

I think I found the Solution. I am Creating the new Project.

Sliding.java

public class Sliding extends LinearLayout
{
    private Paint innerPaint, borderPaint ;
    public Sliding(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }
    public Sliding(Context context) {
        super(context);
        init();
    }
    private void init() {
        innerPaint = new Paint();
        innerPaint.setARGB(0, 255, 255, 255); //gray
        innerPaint.setAntiAlias(true);
        borderPaint = new Paint();
        borderPaint.setARGB(255, 255, 255, 255);
        borderPaint.setAntiAlias(true);
        borderPaint.setStyle(Paint.Style.STROKE);
        borderPaint.setStrokeWidth(2);
    }
    public void setInnerPaint(Paint innerPaint) {
        this.innerPaint = innerPaint;
    }
    public void setBorderPaint(Paint borderPaint) {
        this.borderPaint = borderPaint;
    }
    @Override
    protected void dispatchDraw(Canvas canvas) {
        RectF drawRect = new RectF();
        drawRect.set(0,0, getMeasuredWidth(), getMeasuredHeight());
        canvas.drawRoundRect(drawRect, 5, 5, innerPaint);
