滚动网格视图时需要隐藏textView

Question

我正在尝试在滚动网格视图时隐藏textView，并在用户停止滚动时再次显示相同的textview。 谁能帮我解决这个问题..？

Answer 1

实现OnScrollListener，然后在onScroll内部使onScroll不可见，并在OnScrollStateChanged方法中检查滚动是否停止并再次使其可见

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
    }
};

您需要set this method on your gridview. 这个对我有用。 我相信它将为您提供帮助。

  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    
        }
    });

Answer 3

试试这个代码：

private OnScrollListener mScrollListener = new OnScrollListener() {

    @Override
    public void onScrollStateChanged(ViewGroup view, int scrollState) {
        if(scrollState == SCROLL_STATE_IDLE)
        {
            tv.setVisibility(View.VISIBLE);
        }
    }
    @Override
    public void onScroll(ViewGroup view, int firstVisibleItem, int visibleItemCount, int totalount)
    {
        tv.setVisibility(View.INVISIBLE);
    }

});

您可以在OnScrollListener使用setVisibility

例：

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); 
    }
});

希望能帮助到你。

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); 
}

}）;

我们在我的应用程序中使用此代码，它可以正常工作，希望对您有用。

尝试这个：

Private OnScrollListener mScrollListener = new OnScrollListener() {

@Override
    public void onScrollStateChanged(ViewGroup view, int scrollState) {
         if(scrollState == SCROLL_STATE_IDLE)
     {
                 mTextView.setVisibility = View.VISIBLE;       
         }
@Override
    public void onScroll(ViewGroup view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                 mTextView.setVisibility = View.INVISIBLE
    }
};
