Need to hide a textView while scrolling a grid view

问题

I'm trying to hide a textView while scrolling a grid view and make the same textview visible again when the user stops scrolling. Can anyone help me fixing this issue..?

回答1:

implement OnScrollListener and then inside the onScroll make the textView invisible and in the OnScrollStateChanged method check if the scroll stopped and make it visibile again

private OnScrollListener mScrollListener = new OnScrollListener() {

    @Override
    public void onScrollStateChanged(ViewGroup view, int scrollState) {
         if(scrollState == SCROLL_STATE_IDLE)
         {
                 textView.setVisibility = View.VISIBLE;       
         }

    @Override
    public void onScroll(ViewGroup view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                 textView.setVisibility = View.INVISIBLE
    }
};

You can use setVisibility in OnScrollListener

Example:

gridview.setOnScrollListener(new OnScrollListener() {
    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {

        if(scrollState == SCROLL_STATE_IDLE)
        {
            textview.setVisibility(View.VISIBLE);   
        }
    }

    @Override
    public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {

        textview.setVisibility(View.GONE); 
    }
});

Hope it helps.

gridView.setOnScrollListener(new OnScrollListener() {

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {

    if(scrollState == SCROLL_STATE_IDLE)
    {
        textview.setVisibility(View.VISIBLE);   
    }
}

@Override
public void onScroll(AbsListView view, int firstVisibleItem,
            int visibleItemCount, int totalItemCount) {

You need to set this method on your gridview. it works for me. I am sure it will help you.

  gridAdmin.setOnScrollListener(new OnScrollListener() {

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {

            if(scrollState == SCROLL_STATE_IDLE)
             {
                     text1.setVisibility = View.VISIBLE;   
             }

        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {

             text1.setVisibility = View.INVISIBLE    
        }
    });
