Set Full Screen out onCreate

Question

I can only set my Activity to Full Screen in onCreate method (before setContentView)?

Is there any way I can set to full screen outside of onCreate?

Thanks

Answer 1

Is possible! Adding this code.

    // go full screen
    WindowManager.LayoutParams attrs = mActivity.getWindow().getAttributes();
    attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
    mActivity.getWindow().setAttributes(attrs);

    // go non-full screen
    WindowManager.LayoutParams attrs = mActivity.getWindow().getAttributes();
    attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
    mActivity.getWindow().setAttributes(attrs);

The docs for Window.requestFeature says:

This must be called before setContentView().

so no, I don't believe there is another way to set to full screen after you call setContentView.
