我已经声明了一个 AppWidgetProvider 使用
<receiver android:name="uk.co.bmc.rad.widgets.NearestOpenCragWidgetProvider" android:exported="false">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data android:name="android.appwidget.provider"
android:resource="@xml/nearest_open_crag_widget_info" />
</receiver>
在 res/xml 我添加了nearest_open_crag_Widget_info.xml 包含
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" >
android:minWidth="486dp"
android:minHeight="144dp"
android:updatePeriodMillis="86400000"
android:initialLayout="@layout/nearest_open_crag_widget"
android:resizeMode="none">
</appwidget-provider>
我在 Eclipse 模拟器中运行它,无论我为 minWidth 和 minHeight 指定什么尺寸,都会添加相同尺寸的小部件。
正如您在屏幕底部看到的那样:
如果布局有问题,我会在此处包含它。我(希望)根据状态隐藏或显示三个相对布局
