Answer 1

如何在timerTask run.Exception中进行吐司是未被捕获的处理程序

因为在非ui线程上执行的TimerTask的run方法显示Toast。

为了解决问题，请使用Handler或runOnUiThread来显示来自run方法的Toast

你还没有用过

        HTML

        <div id="slider">
        <img id="1" src="Images/IMG_2615.png" style="hight:1048px; width:1571px;" alt="" />
        <img id="2" src="Images/IMG_2616.png" style="hight:1048px; width:1571px;" alt="" />
        <img id="3" src="Images/IMG_2619.png" "hight:1048px; width:1571px;" alt="" />
        <iframe id="4" width="100%" height="100%" src="http://www.youtube.com/embed/KVwSP51KVO8?wmode=opaque" frameborder="0" class="youtube-video" allowfullscreen></iframe>
        <img id="5" src="Images/IMG_2620.png" "hight:1048px; width:1571px;" alt="" />
        <img id="6" src="Images/IMG_4189.JPG" "hight:1048px; width:1571px;" alt="" />
        <img id="7" src="Images/IMG_4245.JPG" "hight:1048px; width:1571px;" alt="" />
        <img id="8" src="Images/IMG_4283.JPG" "hight:1048px; width:1571px;" alt="" />
    </div>
    <!-- Background Slideshow -->`

CSS

#slider {
overflow: hidden;
/* Set rules to fill background */
min-height: 100%;
min-width: 100%;

/* Set up proportionate scaling */
width: 100%;
height: auto;

/* Set up positioning */
position: fixed;
top: 0;
left: 0;
z-index: -1;}

#slider > img {
float: left;
display: none;
//height: 1048px;
//width: 1571px;}

#slider iframe {
float: left;
//display: none;}



JS

 sliderInt = 1;
 sliderNext = 2;

 $(document).ready(function(){
 $('#slider>Img#1').fadeIn(1000);
 startSlider();
 });


function startSlider() {
count = $('#slider>Img').size();

loop = setInterval(function () {

    if(sliderNext > count) {
        sliderNext = 1;
        sliderInt = 1;
    }

    $('#slider>Img').fadeOut(1000);
    $('#slider>Img#'+ sliderNext).fadeIn(1000);

    sliderInt = sliderNext;
    sliderNext = sliderNext + 1;
}, 7000)

在你的祝酒词中。

这应该是

.show();

而不是

Toast.makeText(getApplicationContext(),"ringing",Toast.LENGTH_SHORT).show();
