Activity父类中加入子类内容的方法

BaseActivity.java

 @Override
    public void setContentView(int rootViewId) {
        LayoutInflater inflator = getLayoutInflater();

        ViewGroup allContent = (ViewGroup)inflator.inflate(R.layout.base_authenticated_screen, null);

        ViewGroup content = ((ViewGroup)allContent.findViewById(R.id.screen_content)); // R.id.screen_content是放置子类内容的ViewGroup
        content.removeAllViews();
        content.addView(inflator.inflate(rootViewId, null));

        super.setContentView(allContent);
    }
