Android-->Launcher拖拽事件详解

http://blog.csdn.net/gf771115/article/details/8152837

//Launcher初始化――LauncherApplication

public class LauncherApplication extends Application

{

}

点击桌面图标：

\AC8317_Native_Launcher\src\com\android\launcher3\Launcher.java

public void onClick(View v){}

public void funcLauncherSetting()

{

Intent intent = new Intent();

intent.setAction("android.intent.action.MAIN");

intent.addCategory("android.intent.category.LAUNCHER");

intent.setComponent( new ComponentName("com.android.settings", "com.android.settings.SettingMainActivity"));

//intent.setComponent( new ComponentName("com.android.settings", "com.android.settings.Settings"));

mContext.startActivity(intent);

}

dimens.xml

//修改桌面ICON大小: app_icon_size

//修改ICON与文字之间的距离

Workspace.java桌面

AppsCustomizePagedView.java进入主菜单

删除应用图标或卸载应用程序

onDropCompleted(View target, DragObject d, boolean isFlingToDelete, boolean success)

安装APK后，AllAppsList.java

public void addPackage(Context context, String packageName) {

final List<ResolveInfo> matches = findActivitiesForPackage(context, packageName);

if (matches.size() > 0) {

for (ResolveInfo info : matches) {

add(new ApplicationInfo(context.getPackageManager(), info, mIconCache, null));

}

Hotseat中间主菜单那个按钮:

Hotseat.java

void resetLayout()

{

allAppsButton.setOnClickListener(new View.OnClickListener()

{

@Override

public void onClick(android.view.View v)

{

}

void showWorkspace(boolean animated, Runnable onCompleteRunnable)

{

}

public void showAllApps(boolean animated)

{

}

//在主桌面长按图标

//Launcher.java

public boolean onLongClick(View v)

{

}

/** The different states that Launcher can be in. */

private enum State

{

NONE, WORKSPACE, APPS_CUSTOMIZE, APPS_CUSTOMIZE_SPRING_LOADED

};

WORKSPACE:主桌面

APPS_CUSTOMIZE:应用列表APP_LIST

APPS_CUSTOMIZE_SPRING_LOADED:在应用列表中长按应用图标

由launcher处理主桌面布局,主桌面每一页就是一个cell,如cell1，cell2，cell3等，就是代表第一到第三页。主桌面的最下面一排的hotset也是在这里

主桌面自定义的控件（如第一页的时钟天气等控件）是在这里处理：

E:\work\android\RK_Common_UI\Code\Px4_Native_Launcher\res\layout\custom_appwidget_kaisida.xml

全部应用列表ALLAPP， ICON图标和ICON文字的配置文件：

E:\work\android\RK_Common_UI\Code\Px4_Native_Launcher\res\layout \apps_customize_application_kaisida.xml

E:\work\android\RK_Common_UI\Code\Px4_Native_Launcher\src\com\oklcom4\launcher3

\AppsCustomizePagedView.java

public void syncAppsPageItems(int page, boolean immediate)

{

PagedViewIcon icon;

icon = (PagedViewIcon) mLayoutInflater.inflate(

R.layout.apps_customize_application_kaisida, layout, false);

}

主桌面 ICON图标和ICON文字的配置文件：

E:\work\android\RK_Common_UI\Code\Px4_Native_Launcher\res\layout\application_kaisida.xml

android:layout_gravity="center_horizontal|top"

android:layout_gravity="center_horizontal|center"

android:layout_gravity="center_horizontal|bottom"

E:\work\android\RK_Common_UI\Code\Px4_Native_Launcher\src\com\oklcom4\launcher3

\Workspace.java

void addApplicationShortcut(ShortcutInfo info, CellLayout target, long container, int screen,

int cellX, int cellY, boolean insertAtFirst, int intersectX, int intersectY)

{

View view;

view = mLauncher.createShortcut(R.layout.application_kaisida, target,

(ShortcutInfo) info);

}
