Hello oh great wizards of all things android. I really need your help. Mostly because my little brain just doesn't know were to start. I am trying to pull data from the internet to make a widget for the home screen. I have the layout built:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/Layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/widget_bg_normal"
android:clipChildren="false"
>
<TextView
android:id="@+id/text_view"
android:layout_width="100px"
android:layout_height="wrap_content"
android:paddingTop="18px"
android:layout_centerHorizontal="true"
android:textSize="8px"
android:text="158x154 Image downloaded from the internet goes here. Needs to be updated every evening at midnight or unless the button below is pressed. Now if I could only figure out exactly how to do this, life would be good."
/>
<Button
android:id="@+id/new_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Get New"
android:layout_below="@+id/scroll_image"
android:layout_centerHorizontal="true"
android:padding="0px"
android:textSize="10px"
android:height="8px"
android:includeFontPadding="false"
/>
</RelativeLayout>
Got the provider xml bulit:
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider
xmlns:android="http://schemas.android.com/apk/res/android"
android:minWidth="150dip"
android:minHeight="150dip"
android:updatePeriodMillis="10000"
android:initialLayout="@layout/widget"
/>
The Manifest works great.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dge.myandroid"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".myactivty"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<!-- Widget -->
<receiver
android:name=".mywidget"
android:label="@string/app_name"
>
<intent-filter>
<action
android:name="android.appwidget.action.APPWIDGET_UPDATE"
/>
</intent-filter>
<meta-data
android:name="android.appwidget.widgetprovider"
android:resource="@xml/widgetprovider"
/>
</receiver>
<!-- Widget End -->
</application>
<uses-permission android:name="android.permission.INTERNET" />
<uses-sdk android:minSdkVersion="7" />
</manifest>
The data it is calling looks something like this when it is called. It basically goes to a website that uses php to random the image:
<html><body bgcolor="#000000">center>
<a href="http://www.website.com" target="_blank">
<img border="0" src="http://www.webiste.com//0.gif"></a>
<img src="http://www.webiste.com" style="border:none;" />
</center></body></html>
But here is were I am stuck. I just don't know where to start at all. The java is so far beyond my little head that I don't know what to do.
package com.dge.myandroid;
import android.appwidget.AppWidgetProvider;
public class mywidget extends AppWidgetProvider {
}
The wiki example just confused me more. I just don't know where to begin. Please help.
