How to align a button to bottom of screen

Question

I have added a Button to my WebView. But I cannot get it to align to bottom of screen. I have given the code below.

Button button = new Button(context);
button.setText("Button");
LayoutParams params1 = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
params1.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
button.setLayoutParams(params1);
webView.addView(button);

Does anyone know how to do this.

Answer 1

For your concern try like this :;

Button btn1 = (Button) findViewById(R.id.btn1);

        btn1.setGravity(Gravity.BOTTOM);

UPDATE :: Try some thing like this for the button U need to place at bottom of screen

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dip"
        android:layout_weight="1"
        android:gravity="center|bottom"
        android:orientation="vertical" >


        <Button
            android:id="@+id/button3"
            style="?android:attr/buttonStyleSmall"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal|center"
            android:text="3" />
    </LinearLayout>

Answer 2

You can try with an LinearLayout and gravity :

    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    params.gravity=Gravity.BOTTOM;

Ok I got the solution. I did button.setY(screenHeight-button.getHeight());
