Question

所有图片的背景同时改变。我必须一个一个地更改，在每张图片后等待5秒钟，再更改另一张，

ImageView[] imajlar={img1,img2,img3,img4,img5,img6,img7,img8};

for (final ImageView resmi:imajlar) {
//resmi.startAnimation(fadeout);
   new CountDownTimer(16000, 1000) {
   @Override
   public void onTick(long millisUntilFinished) {
        resmi.setBackground(hediye);
        resmi.startAnimation(fadein);
        onPause();
   }

   @Override
   public void onFinish() {

   }
   }.start();

Answer 1

为此使用Handler。希望对您有帮助。

new Handler().postDelayed(new Runnable(){
       @Override
       public void run() {
           changeImage();
       }
}, 5000);

Answer 2

尝试此代码。

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        // define your code..
    }
},5000);

Answer 3

喜欢做

定义图像数组。

String img[]={img1,img2,img3};

和一个变量

int i=0;

现在在您的方法中

changeImage()
{
if(i<img.length())
{
//Pseudo code(your logic of setting image)
setImage.array[i];
i++;
}
else
{
//This is to start again;
i=0
}
}

然后在您定义的处理程序中。

final Handler mHandler=new Handler();
ha.postDelayed(new Runnable() {

    @Override
    public void run() {
       changeImage();

        mHandler.postDelayed(this, 5000);
    }
}, 5000);

Answer 4

使用处理程序尝试计时器

 Timer timer = new Timer();
            timer.scheduleAtFixedRate(new TimerTask() {
                @Override
                public void run() {

                   //Your code
                }
            }, 0, 5000);

Answer 5

int totalImageSize = yourTotalImageCount;

        final Handler mHandler = new Handler();
        mHandler.postDelayed(new Runnable() {

            @Override
            public void run() {
                changeYourImage(totalImageSize);// this will give the position of image to add/remove
                totalImageSize - 1;
                if(totalImageSize > 0)
                mHandler.postDelayed(this, 5000);
            }
        }, 5000);
    }
