Android adding footer to ListView addFooterView()?

Question

I have a ListView activity that needs a footer to the list of items so that you can click it and it would load more items into the list. The list is backed my an SimpleAdapt

Answer 1

View footerView = getLayoutInflater().inflate(R.layout.search_footer,
            mContentList, false);
    LongButton mSearchMoreBtn = (LongButton) footerView
            .findViewById(R.id.searchmore_btn);
    mSearchMoreBtn.setText(R.string.search_moreapp);//the button to add 
    mSearchMoreBtn.setBackgroundResource(R.drawable.btn_long_selector);
    mSearchMoreBtn.setOnClickListener(mSearchMoreBtnListener);

    footerView.setOnClickListener(mLoadMoreAppsListener);
    mContentList.addFooterView(footerView);  

I have no idea that when I adding mSearchMoreBtn to ListView as footerView, it is wrong, instead, when I adding footerView to ListView, it just fine
