单击按钮后，如何在指定的时间内显示图像？ 日食

Question

Just wondering how I can make a button click make an image view appear for like half a sec then disappear, until the button is clicked again. I'm using joda-time

Here's what I have. I'm new to java if you couldn't already tell.

public void onClick(View v) {   
    // TODO Auto-generated method stub 
    dur = 1;
    if (barrelblast != 0)
        sp.play(barrelblast, 1, 1, 0, 0, 1);  
            Vibrator vibe = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);
        vibe.vibrate (90);  

    if (dur != 0)
       smoke.setVisibility(View.VISIBLE);
       Duration.standardSeconds(1); 

Answer 1

You can try this:

public void onClick(View v){

smoke.setVisibility(View.VISIBLE);
Handler delayedAction = new Handler();

delayedAction.postDelayed(new Runnable() {

public void run() {

smoke.setVisibility(View.INVISIBLE);

                }

       }, 500);

}
