How to create toast from IntentService? It gets stuck on the screen

由 ☆樱花仙子☆ 提交于 2019-11-27 01:47:59
问题 I'm trying to have my IntentService show a Toast message, but when sending it from the onHandleIntent message, the toast shows but gets stuck and the screen and never leaved. I'm guessing its because the onHandleIntent method does not happen on the main service thread, but how can I move it? Has anyone has this issue and solved it? 回答1: in onCreate() initialize a Handler and then post to it from your thread. private class DisplayToast implements Runnable{ String mText; public DisplayToast

Since I have to do call some javascript on the loaded page I cannot use any HttpGet's etc. I therefore have to use a WebView instance which can only run on an UI thread. Any attempts to start an Activity that use a WebView results in a View coming into the phones foreground (as per Android's design of Activities) Any attempts to use a WebView outside of an Activity context resulted in error pointing to the fact that you cannot use WebView on a

问题 I have an IntentService that is started from an Activity and I would like to be able to stop the service immediately from the activity with a \"cancel\" button in the activity. As soon as that \"cancel\" button is pressed, I want the service to stop executing lines of code. I\'ve found a number of questions similar to this (i.e. here, here, here, here), but no good answers.
