Android set Layout align left and center vertical programmatically

Question

I want to have arrowview overlap on homeview in center vertical left. I have tried to do so using couple of views but didn't work. It shows me overlap but on left top corner instead of left center vertical. Please help me.

private RelativeLayout makeContentView1() {
    RelativeLayout arrowView = new RelativeLayout(this);
    arrowView.setBackgroundResource(R.drawable.image);
    //RelativeLayout.LayoutParams relativeParams = (RelativeLayout.LayoutParams)arrowView.getLayoutParams();
    //relativeParams.setMargins(0, 80, 0, 0);
    //arrowView.setLayoutParams(relativeParams);
    arrowView.setGravity(RelativeLayout.CENTER_VERTICAL | RelativeLayout.ALIGN_LEFT);
    return arrowView;

}

public void makeLayout() {
    homeView = new RelativeLayout(this);
    LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);

    homeView.setLayoutParams(lp);

    bodyView = this.makeBodyView();
    arrowView = this.makeContentView1(300,300);

    homeView.addView(bodyView);
    homeView.addView(arrowView);

    return homeView;

}

You can achive your task by using a single RelativeLayout with applying rules on it, Use the below code to achive this,

private RelativeLayout makeContentView1() {
    RelativeLayout arrowView = new RelativeLayout(this);
    arrowView.setBackgroundResource(R.drawable.image);


    return arrowView;
}

public void makeLayout() {
    homeView = new RelativeLayout(this);
    LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.MATCH_PARENT);

    homeView.setLayoutParams(lp);

    bodyView = this.makeBodyView();
    arrowView = this.makeContentView1(300,300);

    homeView.addView(bodyView);
    homeView.addView(arrowView);

    RelativeLayout.LayoutParams relativeParams =       (RelativeLayout.LayoutParams)arrowView.getLayoutParams();
    relativeParams.addRule(RelativeLayout.CENTER_VERTICAL);
    arrowView.setLayoutParams(relativeParams);
return homeView;

}
