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。

Q1: android 中仿QQ显示说说 用什么控件
这个属于调用系统相册和系统相机进行图片选择的问题

Q2: 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);
}
}
