android仿QQ在对应组件位置，弹出选项框是怎么实现的

可以用popupwindow，dialog是达不到效果的，dialog会覆盖到整个屏幕上面的，要么就修改dialog的theme。

android仿QQ右上角显示未读消息个数，求助

监听消息，得到数目，在app图标上画出数字（canvas），然后替换桌面快捷方式

public void createShortCut(){

//创建快捷方式的Intent

Intent shortcutintent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");

//不允许重复创建

shortcutintent.putExtra("duplicate", false);

//需要现实的名称

shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));

//快捷图片(每次重绘logo生成一张新图)

Parcelable icon = Intent.ShortcutIconResource.fromContext(activity, R.drawable.logo);

shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, icon);

//点击快捷图片，运行的程序主入口

shortcutintent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent());

//发送广播。OK

sendBroadcast(shortcutintent);

}

}
