Launcher3.apk 是android系统的桌面应用。其源码在frameworks/base/packages/apps目录下。其apk在设备上的位置:/system/priv-app/Launcher3/。
launcher3\src\main\java\com\android\launcher3\Launcher.java
private void setupViews() {
...
mSearchDropTargetBar = (SearchDropTargetBar)
mDragLayer.findViewById(R.id.search_drop_target_bar);
//隐藏首页搜索栏
mSearchDropTargetBar.setVisibility(View.GONE);
....
}
同一热键在水平方向
1 修改launcher3\src\main\res\values\config.xml
<!-- android会根据不同设备水平或垂直显示热键的方向,在此改为false,表示统一水平,不转置 -->
<bool name="hotseat_transpose_layout_with_orientation">false</bool>
2 修改Launcher64\launcher3\src\main\java\com\android\launcher3\Hotseat.java
protected void onFinishInflate() {
...
mAllAppsButtonRank = grid.hotseatAllAppsRank;
mContent = (CellLayout) findViewById(R.id.layout);
//本来判断设备是那种布局和类型,决定横向还是竖向的排布热键
/* if (grid.isLandscape && !grid.isLargeTablet()) {
mContent.setGridSize(1, (int) grid.numHotseatIcons);
} else {
mContent.setGridSize((int) grid.numHotseatIcons, 1);
}*/
//改成都水平排布,即一行多列
mContent.setGridSize((int) grid.numHotseatIcons, 1);
mContent.setIsHotseat(true);
resetLayout();
}
修改launcher3\src\main\res\values\config.xml
<!--允许屏幕旋转-->
<bool name="allow_rotation">true</bool>
修改launcher3\src\main\java\com\android\launcher3\LauncherClings.java
//不显示开机小提示
private static final boolean DISABLE_CLINGS = true;
