当我们在应用程序Launcher的桌面空白处长按触摸时，会出现一个对话框，提示选择要添加的桌面组件，如下图所示
选择快捷方式后，会弹出一个对话框，显示出了可添加快捷方式的Activity所属的应用程序的图标和名称的列表。当我们想把添加快捷方式的Activity添加到这一列表时，只需要在这个Activity注册时添加一个Action为android.intent.action.CREATE_SHORTCUT的IntentFilter就可以了。
ShortCutAction类
package com.ljq.action;
import android.app.Activity;
import android.os.Bundle;
/**
* 向Launcher添加快捷方式

public class ShortCutAction extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super .onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
