android1.6的版本有3个屏需要把它改�?个屏需要修改的地方如下

1、Launcher.java

Java代码  收藏代码

    static final int SCREEN_COUNT = 5;
    static final int DEFAULT_SCREN = 2;

2、launcher.xml

Java代码  收藏代码

    <com.lp.launcher.Workspace
            android:id="@+id/workspace"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"

            launcher:defaultScreen="2">//�?开�?nbsp;

            <include android:id="@+id/cell1" layout="@layout/workspace_screen" />
            <include android:id="@+id/cell2" layout="@layout/workspace_screen" />
            <include android:id="@+id/cell3" layout="@layout/workspace_screen" />
            <include android:id="@+id/cell4" layout="@layout/workspace_screen" />
            <include android:id="@+id/cell5" layout="@layout/workspace_screen" />

    com.lp.launcher.Workspace>

defaultScreen 修改�? 然后加两�?/span><include />

然后修改默认昄��的屏

3、Workspace.java

修改构造方法里面的
Java代码  收藏代码

    mDefaultScreen = a.getInt(R.styleable.Workspace_defaultScreen, 2);//�?开�?nbsp;

�q�时基本上已�l�可以显�C?个屏�q�了(ji��n) 默认的屏也是�W�三个屏�?nbsp;但是�q�去�?nbsp;默认昄��的屏什么也没有我们需要把�l�徏都挪到默认屏上去

在Hotseat->resetLayout->删除mContent.addViewToCellLayout(allAppsButton, -1, 0, new CellLayout.LayoutParams(x,y,1,1), true);
