核心:重新生成快捷方式

在小米 三星索尼 手机 :图标上显示数字(未读消息数):这部分代码,是从QQ5.0.apk中找的。

小米已经测试通过了,

三星和索尼的,由于没有相应的手机,没有测试,有的,可能修改一下代码(判断是什么手机的代码),

测试一下,可以在回复一下测试结果,谢谢

1.原生系统(原生的 Launcher ),只能修改快捷方式,增加和删除都会有toast提示

2.小米 三星索尼 手机: 自定义的launcher:发送显示未读消息数的action已经不同了。具体可以去看代码。。。

判断手机的代码:

     
 
     

/***

* 在应用图标的快捷方式上加数字

* @param clazz 启动的activity

* @param isShowNum 是否显示数字

* @param num 显示的数字:整型

* @param isStroke 是否加上边框

*

*/

public static void addNumShortCut(Context context,Class< ?> clazz,boolean isShowNum, String num, boolean isStroke)

{

Log.e(TAG, "manufacturer="+Build.MANUFACTURER);

if (Build.MANUFACTURER.equalsIgnoreCase("Xiaomi")){

//小米

xiaoMiShortCut(context, clazz, num);

}else if(Build.MANUFACTURER.equalsIgnoreCase("samsung")){

//三星

samsungShortCut(context, num);

}else {//其他原生系统手机

installRawShortCut(context, MainActivity.class, isShowNum, num, isStroke);

}

}

复制代码 下面写好的工具类,上面的方法也在其中。
