Horizontal Scroll View Width in Android?

How can I set a width for Horizontal 开发者_JAVA百科Scroll View?

myHorizontalScrollView.setWidth();

This doesnt appear to work, I need to limit the scroll views width.

ViewGroup.LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT
        ,LayoutParams.FILL_PARENT);
myHScrollView.setLayoutParams(lp);

You can set the width and height using the layout parameters object.

To set exact number as width you need to use the TypedValue class

int value = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_PX, 
                 (float) 200, getResources().getDisplayMetrics());

And the int should be set in the LayoutParams constructor.

ViewGroup.LayoutParams lp = new LayoutParams(width ,height);
myHScrollView.setLayoutParams(lp);

Also you can set width and height to wrap_content and fill_parent

Set your scrollview to fill the parent's width and make that parent 200dp wide
