如何让Launcher支持横屏显示

如何让Launcher3支持横屏显示？

N/M：

Launcher默认支持横屏显示，只需要按如下操作即可开启横屏显示：

桌面空白处长按→进入OverviewMode→点击设置→打开允许旋转的开关

L：

1.修改AndroidManifest.xml

 <activityandroid:name="com.android.launcher3.Launcher"android:launchMode="singleTask"android:clearTaskOnLaunch="true"android:stateNotNeeded="true"android:theme="@style/Theme"android:configChanges="mcc|mnc"android:windowSoftInputMode="adjustPan"android:screenOrientation="sensor"> <!--modify to sensor -->

2.修改Utilities.java的isRotationEnabled方法

 public static boolean isRotationEnabled(Context c)       {           return true;//直接返回true       }

此时旋转手机，Launcher会横竖屏切换。但hotseat会显示在屏幕的右方。如果要让hotseat显示在屏幕底部，可以按照如下步骤操作

3.修改res/values/config.xml

 <!--hotseat -->    <bool name="hotseat_transpose_layout_with_orientation">false</bool> <!--改为false-->

4.修改Hotseat.java的onFinishInflate方法

@Override     protected void onFinishInflate() {super.onFinishInflate();LauncherAppState app = LauncherAppState.getInstance();DeviceProfile grid = app.getDynamicGrid().getDeviceProfile();mAllAppsButtonRank = grid.hotseatAllAppsRank;mContent = (CellLayout) findViewById(R.id.layout);if (grid.isLandscape && !grid.isLargeTablet()) {mContent.setGridSize((int) grid.numHotseatIcons, 1); //modify} else {mContent.setGridSize((int) grid.numHotseatIcons, 1);}mContent.setIsHotseat(true);Log.i(TAG, "onFinishInflate,(int) grid.numHotseatIcons: " + (int) grid.numHotseatIcons);resetLayout();}
