复制提示
activity.runOnUiThread(new Runnable() {
public void run()
{
Toast.makeText(context, toast, Toast.LENGTH_SHORT).show();
}
});
run()方法没有执行,查找原因,在原来,掉用runOnUiThread的activity,一定得是Activity对象,so,在使用之前,需要增加判读:
if(activity instanceOf Activity){
}

原文:
It doesn't always work, you have to be sure that what you are casting is
effectively an Activity or you'll have a ClassCastException. To do that you can do
"if(context instanceOf Activity){ // proceed to cast }"
