Android Adding Buttons to Toolbar Programmatically

I am trying to create a toolbar programmatically and add left and right bar buttons without using XML.

But the button is not getting aligned to right.

Toolbar TopTulBarVar = new Toolbar(this);
TopTulBarVar.setId(View.generateViewId());
TopTulBarVar.setBackgroundColor(Color.parseColor("#DDDDDD"));
TopTulBarVar.setTitle("Ttl Txt");
TopTulBarVar.setSubtitle("Dtl Txt");

Button NamBarBtnVar = new Button(this);
NamBarBtnVar.setText("Select");
NamBarBtnVar.setBackgroundColor(Color.GREEN);
LinearLayout.LayoutParams NamBarBtnRulVar = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
NamBarBtnRulVar.gravity = Gravity.RIGHT;
TopTulBarVar.addView(NamBarBtnVar, NamBarBtnRulVar);

Also tried

RelativeLayout.LayoutParams RloRulVar = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    RloRulVar.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);

I am getting as below image

In Activity code

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar t = (Toolbar) findViewById(R.id.tool);
    setSupportActionBar(t);
    getSupportActionBar().setDisplayShowTitleEnabled(false);

    //left side button

    Button b = new Button(this);
    Toolbar.LayoutParams l1=new Toolbar.LayoutParams(Toolbar.LayoutParams.WRAP_CONTENT, Toolbar.LayoutParams.WRAP_CONTENT);
    l1.gravity = Gravity.START;
    b.setLayoutParams(l1);
    b.setText("left");
    t.addView(b);

    //center Textview
    TextView text=new TextView(this);
    text.setText("Text:1");
    Toolbar.LayoutParams l2 = new Toolbar.LayoutParams(Toolbar.LayoutParams.WRAP_CONTENT, Toolbar.LayoutParams.WRAP_CONTENT);
    l2.gravity = Gravity.CENTER;
    text.setLayoutParams(l2);
    t.addView(text);

    //Right side button

    Button b1=new Button(this);
    b1.setText("Right");
    Toolbar.LayoutParams l3=new Toolbar.LayoutParams(Toolbar.LayoutParams.WRAP_CONTENT, Toolbar.LayoutParams.WRAP_CONTENT);
    l3.gravity=Gravity.END;
    b1.setLayoutParams(l3);
    t.addView(b1);

}

Toolbar XML code

<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:background="@color/colorAccent"
android:id="@+id/tool"
app:contentInsetLeft="0dp"
android:paddingRight="10dp"
android:paddingLeft="10dp"
app:contentInsetStart="0dp"
app:contentInsetStartWithNavigation="0dp"
android:layout_height="wrap_content">

</android.support.v7.widget.Toolbar>
