創建和配置窗口小部件
要註冊您創建的android.appwidget.action.APPWIDGET_UPDATE行動的意圖過濾器一個BroadcastReceiver一個小部件。
<receiver
android:icon="@drawable/icon"
android:label="Example Widget"
android:name="MyWidgetProvider" >
<intent-filter >
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
android:name="android.appwidget.provider"
android:resource="@xml/widget_info" />
</receiver>
您還指定的元數據,通過Android窗口小部件:NAME =「android.appwidget.provider屬性由這個元數據所指的配置文件包含的配置設置如果包含例如更新界面,小部件的大小和初始佈局
在/ res/drawable目錄中創建一個新文件myshape.xml。該文件將定義我們在您的小部件中使用的背景。
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<stroke
android:width="2dp"
android:color="#FFFFFFFF" />
<gradient
android:angle="225"
android:endColor="#DD2ECCFA"
android:startColor="#DD000000" />
<corners
android:bottomLeftRadius="7dp"
android:bottomRightRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp" />
</shape>
在res/layout文件夾下定義以下widget_layout.xml
文件。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="8dip"
android:background="@drawable/myshape" >
<TextView
android:id="@+id/update"
style="@android:style/TextAppearance.Medium"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center_horizontal|center_vertical"
android:layout_margin="4dip"
android:text="Static Text" >
</TextView>
</LinearLayout>
現在成爲班級。
public class MyWidgetProvider extends AppWidgetProvider {
private static final String ACTION_CLICK = "ACTION_CLICK";
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// Get all ids
ComponentName thisWidget = new ComponentName(context,
MyWidgetProvider.class);
int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
for (int widgetId : allWidgetIds) {
// Create some random data
int number = (new Random().nextInt(100));
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
Log.w("WidgetExample", String.valueOf(number));
// Set the text
remoteViews.setTextViewText(R.id.update, String.valueOf(number));
// Register an onClickListener
Intent intent = new Intent(context, MyWidgetProvider.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.update, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
}
我發現整天解決第一個和第二個要求,完成了。 – Harshid 2013-02-25 07:17:11
