Question

我已经使用

声明了一个AppWidgetProvider

        <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中我添加了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指定的大小，小部件都添加了相同的尺寸。

正如您在屏幕底部所见： screenshot

如果布局出现问题，我会在此处加入。根据状态

我有三个RelativeLayouts（希望是）隐藏或显示

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

</LinearLayout>

非常感谢提前

Answer 1

它不会忽略您的设置

请在此处阅读http://developer.android.com/guide/practices/ui_guidelines/widget_design.html

如果您的窗口小部件背景九补丁中有任何固有内容填充，您应该相应地添加到minWidth和minHeight。

Answer 2

您需要将相同的minHeight或minWidth应用于children元素（看起来很迟钝，不是吗？）

如果您将相同的设置调整为子项，则appwidget-provider中的设置会起作用，我的情况如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:padding="@dimen/widget_margin"
    android:background="#525252" 
    android:minWidth="486dp"
    android:minHeight="144dp">

如何修复AppWidgetProvider的声明，忽略minwidth和minheight
