toast

问题 I have a problem. I'm using a FileObserver , which moves new files from the watched directories to another, former specified directory. In my thoughts there should be shown a toast message that says 'File xy has been moved', as long as the observer watches the directory, also if the applications is only in the background. But I didn't get it working. It always tells me, that there is a RuntimeException , and that it cannot been done without calling Looper.prepare() . 05-11 13:21:28.484: WARN

问题 In one of my methods, I have a toast that appears if the user gives the correct input. However, I do not want the next image to display until the toast has finished. If I use Thread.sleep(3000) if does not allow the toast to show as the UI activity is asleep. An example of what I am trying to do: public void correction(){ if(correctionBoolean == true){ Toast.makeText(this, "Correct!", Toast.LENGTH_SHORT).show(); if(Toast.time == finished){ NextImage();} } 回答1: I don't believe there would be

问题 I have a custom toast notification which has an image and text. The custom toast works fine however I am wondering how do I make my custom toast inherit the default toasts look and feel?

问题 Can I set some message to appear like a "tooltip" for a TextView or Button? 回答1: There's no concept of "hovering" in a touch screen, but you could set a LongClickListener for your View, and have a Toast appear after a long press. Something like this: Toast viewToast = Toast.makeText(this, "My View Tooltip", Toast.LENGTH_SHORT); View myView = (View)findViewById(R.id.my_view); myView.setOnLongClickListener(new OnLongClickListener() { @Override public void onLongClick(View v) { viewToast.show();

问题 I've looked through a heap of previous answers on this , and tried the code marked as working, but so far nothing I do can convince the TextView I'm creating at runtme from filling the screen completely from left to right. I want to add a margin on both sides similar to a regular Toast. After that I can add a drop shadow to the shape. Here my form layout. <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id

问题 Quite new to Android development and Java in general, so please excuse any amateur ignorance and lack of terminology. I'm working on an Android app that involves fetching Web pages as strings, using a method based on the code available at http://www.spartanjava.com/2009/get-a-web-page-programatically-from-android/. This takes a small but noticeable amount of time, but works fine. It is triggered by pressing a button in the UI. Since the application is unresponsive while data is being fetched,

问题 I would like to create a simple toast notification using python v3.6 on Windows10 machine.

问题 When the user clicks on the save button, an AlertDialog appears and asks the user to input text for the file name. If the user clicks the positive button ("Ok") without specifying a name, I want to display a toast which asks them to do so, and keep the AlertDialog open. But the toast never displays and the dialog closes. The code for the AlertDialog is here: AlertDialog.Builder alert = new AlertDialog.Builder(this); alert.setTitle(R.string.save_game); alert.setMessage(R.string.request_name);

问题 Does anybody know if there exist some implementation of some popup window, something like in Android: TOAST ? 回答1: The notifications are part of Mylyn commons. To integrate them, add the Mylyn Commons Notifications feature from http://download.eclipse.org/mylyn/releases/latest to your target platform definition. The relevant bundles are org.eclipse.mylyn.commons.notifications.ui org.eclipse.mylyn.commons.notifications.core . You can add a category and an event to the notifications extension
