How to delay spawned thread when a Runnable run on UI thread isn't an option?

由 爱⌒轻易说出口 提交于 2019-12-23 04:11:23
问题 I had issues with a previous question where I was unsure whether my code had a memory leak. A few answers were concerned with it being run on the UI thread and so blocking. It is true, it runs on the UI thread and doesn't spawn a new one.. So to solve it I use Thread instead of Handler to spawn a new thread outside of UI.

Running a method on UI thread

由 吃可爱长大的小学妹 提交于 2019-12-13 06:35:28
问题 My question seems very simple but i can't seem to the logic right. Am trying to run methods from other classes using the UI thread. I could do this this simply by wrapping my methods like this runOnUiThread(new Runnable() { public void run() { Log.d("UI thread", "I am the UI thread"); ui.myMethod("changetext"); } }); but my goal is to have a class that wraps methods to be run on the UI thread as having runOnUiThread() almost 5 times in a single class seems very untidy. Any pointers? 回答1: If

问题 localChatManager.addIncomingListener { from, message, chat -> Log.v(TAG,"listener") //You can't modify views from non-UI thread. this@chatActivity.runOnUiThread { object :Runnable{ override fun run() { Log.i(TAG,"runOnUiThread") } } } } I am not able to figure out why runOnUiThread is not working but outside of that method everything is working as usual. 回答1: What you are doing is passing in a lambda to the runOnUiThread function. It will run that lambda, and create an object that inherits

Warning: This AsyncTask class should be static or leaks might occur

问题 I am getting a warning in my code that states: This AsyncTask class should be static or leaks might occur (anonymous android.os.AsyncTask) The complete warning is: This AsyncTask class should be static or leaks might occur (anonymous android.os.AsyncTask) A static field will leak contexts. Non-static inner classes have an implicit reference to their outer class. If that outer class is for example a Fragment or Activity, then this reference means that the long-running handler/loader/task will
