Did you try Your app on emulator or on a real device? If you had set “match_parent” to your Layout, it should work. But I got a similar problem with my Samsung Galaxy S3, it could be that is a hardware error, not your fail.

EDIT

Ok, so if You just use Java-Code without xml definition, maybe you should set the layout-params for the tabhost. I don´t realy know, just an assumption.

    tableHost = new TabHost(this);
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
            LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    tableHost.setLayoutParams(params);

But there are many LayoutParams, don´t know if LinearLayout.LayoutParams are the right one for you. If it doesn´t work, you have to try some other LayoutParams.
