Gridview高度被裁剪我試圖在一個(gè)網(wǎng)格視圖中顯示8個(gè)項(xiàng)目?？杀氖?，網(wǎng)格視圖的高度總是太小，所以它只顯示第一行，以及第二行的一小部分。設(shè)置android:layout_height="300dp"讓它發(fā)揮作用。包裹c(diǎn)ontent和fill_parent顯然不是。我的網(wǎng)格視圖：<GridView
android:id="@+id/myId"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:horizontalSpacing="2dp"
android:isScrollContainer="false"
android:numColumns="4"
android:stretchMode="columnWidth"
android:verticalSpacing="20dp" />我的物品資源：<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:minHeight="?android:attr/listPreferredItemHeight" >
<ImageView
android:id="@+id/appItemIcon"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="@android:drawable/ic_dialog_info"
android:scaleType="center" />
<TextView
android:id="@+id/appItemText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My long application name"
android:gravity="center_horizontal"
android:textAppearance="?android:attr/textAppearanceSmall" /></LinearLayout>這個(gè)問題似乎與缺乏垂直空間無(wú)關(guān)。我能做什么？
