我的幻灯片放映活动是我的列表视图行之一，当单击幻灯片放映行时，它必须打开带有动画的幻灯片图像，但在第一张图像出现之前有大约 25 秒的延迟，我尝试在这里更改时间：

int delay = 1000;

但这并不能解决问题，

任何帮助将不胜感激，谢谢

替换这段代码：

final Handler mHandler = new Handler();
 // Create runnable for posting
 final Runnable mUpdateResults = new Runnable() {
    public void run() {

        AnimateandSlideShow();              
    }
};

int delay = 1000; 

int period = 5000; 

Timer timer = new Timer();

timer.scheduleAtFixedRate(new TimerTask() {

public void run() {

     mHandler.post(mUpdateResults);
}

}, delay, period);

}

改写这段代码： 

final Handler handler = new Handler();   
 runnable = new Runnable() {
     @Override
    public void run() {
        handler.postDelayed(runnable, 5000);
        AnimateandSlideShow();    
    }
};
handler.postDelayed(runnable, 500);
}

这将导致立即启动图像，

然后您可以根据需要控制出现时间和图像之间的时间，

希望对你有所帮助。

尝试使用postdelay：

private int mSampleDurationTime = 5000; // 1 sec
private boolean continueToNext = true;

Handler mHandler = new Handler();

mHandler.postDelayed(mRunnable, mSampleDurationTime);

mRunnable你的任务在哪里：

private final Runnable mRunnable = new Runnable() {

 //...
public void run() {

   // do something here

   if(continueToNext == true){
    mHandler.postDelayed(mRunnable, mSampleDurationTime);
   }

 }
    ...
};
