Android系统 小米，三星，索尼手机发送桌面快键提醒数字图标，在Android系统中，众所周知不支持BadgeNumber，虽然第三方控件BadgeView可以实现应用内的数字提醒，但对于系统的图标，特别是app的logo图标很难实现数字标志，即使是绘图的方式不断修改，但这种方式天生弊端，实用性很差。但幸运的是，某些ROM厂商提供了私有的API，但也带来了难度，API的不同意意味着代码量的增加和兼容性问题更加突出。
我们现在来实现桌面logo或者说icon右上角的图标，先来看2张图，第一张来自互联网，第二张来自个人实践！（由于实验条件有限，只能测试小米的(⊙o⊙)…，有兴趣的同学测试一下其他的吧）
好了，上代码
public class MainActivity extends Activity { //必须使用，Activity启动页 private final static String lancherActivityClassName = Welcome.class.getName(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.common_listview_layout); } @Override protected void onResume() { super.onResume(); sendBadgeNumber(); } private void sendBadgeNumber() { String number = "35"; if (TextUtils.isEmpty(number)) { number = "0"; } else { int numInt = Integer.valueOf(number); number = String.valueOf(Math.max(0, Math.min(numInt, 99))); } if (Build.MANUFACTURER.equalsIgnoreCase("Xiaomi")) { sendToXiaoMi(number); } else if (Build.MANUFACTURER.equalsIgnoreCase("samsung")) { sendToSony(number); } else if (Build.MANUFACTURER.toLowerCase().contains("sony")) { sendToSamsumg(number); } else { Toast.makeText(this, "Not Support", Toast.LENGTH_LONG).show(); } } private void sendToXiaoMi(String number) { NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); Notification notification = null; boolean isMiUIV6 = true; try { NotificationCompat.Builder builder = new NotificationCompat.Builder(this); builder.setContentTitle("您有"+number+"未读消息"); builder.setTicker("您有"+number+"未读消息"); builder.setAutoCancel(true); builder.setSmallIcon(R.drawable.common_icon_lamp_light_red); builder.setDefaults(Notification.DEFAULT_LIGHTS); notification = builder.build(); Class miuiNotificationClass = Class.forName("android.app.MiuiNotification"); Object miuiNotification = miuiNotificationClass.newInstance(); Field field = miuiNotification.getClass().getDeclaredField("messageCount"); field.setAccessible(true); field.set(miuiNotification, number);// 设置信息数 field = notification.getClass().getField("extraNotification"); field.setAccessible(true); field.set(notification, miuiNotification); Toast.makeText(this, "Xiaomi=>isSendOk=>1", Toast.LENGTH_LONG).show(); }catch (Exception e) { e.printStackTrace(); //miui 6之前的版本 isMiUIV6 = false; Intent localIntent = new Intent("android.intent.action.APPLICATION_MESSAGE_UPDATE"); localIntent.putExtra("android.intent.extra.update_application_component_name",getPackageName() + "/"+ lancherActivityClassName ); localIntent.putExtra("android.intent.extra.update_application_message_text",number); sendBroadcast(localIntent); } finally { if(notification!=null && isMiUIV6 ) { //miui6以上版本需要使用通知发送 nm.notify(101010, notification); } } } private void sendToSony(String number) { boolean isShow = true; if ("0".equals(number)) { isShow = false; } Intent localIntent = new Intent(); localIntent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE",isShow);//是否显示 localIntent.setAction("com.sonyericsson.home.action.UPDATE_BADGE"); localIntent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME",lancherActivityClassName );//启动页 localIntent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", number);//数字 localIntent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME",getPackageName());//包名 sendBroadcast(localIntent); Toast.makeText(this, "Sony," + "isSendOk", Toast.LENGTH_LONG).show(); } private void sendToSamsumg(String number) { Intent localIntent = new Intent("android.intent.action.BADGE_COUNT_UPDATE"); localIntent.putExtra("badge_count", number);//数字 localIntent.putExtra("badge_count_package_name", getPackageName());//包名 localIntent.putExtra("badge_count_class_name",lancherActivityClassName ); //启动页 sendBroadcast(localIntent); Toast.makeText(this, "Samsumg," + "isSendOk", Toast.LENGTH_LONG).show(); } }注意lancherActivityClassName 必须被配置为 启动页 android.intent.category.LAUNCHER
