如何使文本視圖出現和消失？

Question

默認是消失。 我想知道如何使text-view出現和消失。

Answer 1

您可以設置特定View's可見性，例如：

yourTextViewName.setVisibility(View.VISIBLE) // For Visible/Appear

yourTextViewName.setVisibility(View.INVISIBLE)  // For Invisible/Disappear

yourTextViewName.setVisibility(View.GONE)   // For Gone / View not takes any space at Run time

希望這會有所幫助。（：

Answer 2

這是您正在尋找的方法；

private void makeTextViewDisappear(){
    yourTV.setVisibility(View.VISIBLE);
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            yourTV.setVisibility(View.INVISIBLE);
            // OR yourTV.setVisibility(View.GONE) to reclaim the space used by textview
        }
    }, 10000); //for 10 seconds
}

如果這有效，請不要忘記將其標記為正確答案。 問候。

Answer 3

new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                   yourTextViewName.setVisibility(View.VISIBLE)
                }
            }, 5000); <--- change time here
