Answer 1

Use a NoActionBar Theme for that activity. This answer can guide you to achieve that.

Answer 2

Please use DisplayMetrics to get w/h you want

DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
RelativeLayout preview_video_parent = (RelativeLayout) findViewById(R.id.preview_video_parent);
LayoutParams layoutParams = (LayoutParams) preview_video_parent
    .getLayoutParams();
layoutParams.width = displaymetrics.widthPixels;
layoutParams.height = displaymetrics.heightPixels;
mTextureView.setLayoutParams(layoutParams);

maybe this could be useful for you : get the camera sizes and set them to the texturuView like this:

Camera mCamera = Camera.open();
Camera.Size previewSize = mCamera.getParameters().getPreviewSize();
TextureView myTexture = (TextureView)findViewById(R.id.texture); 
myTexture.setLayoutParams(new FrameLayout.LayoutParams(previewSize.width, previewSize.height, Gravity.CENTER));
