Android example of updating textview
Currently App Widget layouts are based on Remote Views and android currently supports limited View widget.
Creating layout for the widget is same as creating the layout for other activity type.
But to make a good widget we need to follow the android widget guidelines.
A Remote Views object or App Widget currently supports the following layout classes This is used to describe the metadata for an App Widget, such as the App Widget’s layout, update frequency, and the App Widget Provider class. Below is my App Widget Provider xml configuration file The min Width and min Height attribute is used to specify the minimum amount of space the App Widget consumes by default.
Following steps are required to complete the example: Notice that, we have added Recycler View, Card View support libraries and Picasso dependency module.
It is better to always provide user an option to select the refresh timer frequency.
In the course of this example we will download the data from JSON API, parse and display the items on Recycler View.
As you can notice in the following image, we will be using both Recycler View and Card View for creating the App UI.
We can resize a widget by touch-holding a widget on home screen. Remote Views; public class My Widget Provider extends App Widget Provider Now, we will write a Broadcast Reciever to perform action on the button click. The on Receive() method is requesting the app widget provider for updating the widget. We add an intent filter for the UPDATE_WIDGET event such that your widget will update at regular intervals. From the Home screen, press and hold an empty space to get list if widgets instlled, then choose “Widget Demo” from the list.
resize Mode attribute can be configured to either “horizontal”, “vertical”, and “none”. package com.javatechig.widgetdemo; import android.content. The app widget will then be added to your Home screen.
Recycler View is flexible and efficient version of List View.
