android:ellipsize=start—–省略号显示

android:ellipsize=end——省略号显示结尾

android:ellipsize=middle—-省略号显示间

android:ellipsize=marquee–跑马灯式显示(画横向移)

文字左右滚三属性：

android:singleLine="true"

android:ellipsize="marquee"

android:marqueeRepeatLimit="marquee_forever"

android设置消息角标

xiaomi：

当应用向通知栏发送了一条通知（除了进度条样式和常驻通知外），应用图标的右上角就会显示「1」。值得一提，角标的数字代表应用的通知数，即应用发送了「x」条通知，角标就会显示为「x」。

try {

Field field = notification.getClass().getDeclaredField(“extraNotification”);

Object extraNotification = field.get(notification);

Method method = extraNotification.getClass().getDeclaredMethod(“setMessageCount”, int.class);

method.invoke(extraNotification, mCount);

} catch (Exception e) {

e.printStackTrace();

}

huawei：

BadgeNotification add_num 否 integer 应用角标累加数字非应用角标实际显示数字例如，某应用当前有N条未读消息，若add_num设置为3，则每发一次消息，应用角标显示的数字累加3，为N+3

/** set badge number*/

public void setBadgeNum(int num) {

try {

Bundle bunlde = new Bundle();

bunlde.putString("package", "com.test.badge"); // com.test.badge is your package name

bunlde.putString("class", "com.test. badge.MainActivity"); // com.test. badge.MainActivity is your apk main activity

bunlde.putInt("badgenumber", num);

this.getContentResolver().call(Uri.parse("content://com.huawei.android.launcher.settings/badge/"), "change_badge", null, bunlde);

} catch (Exception e) {

mIsSupportedBade = false;

}

oppo：

老版本方法

private static boolean setOPPOBadge(int count, Context context) {

try {

Bundle extras = new Bundle();

extras.putInt("app_badge_count", count);

context.getContentResolver().call(Uri.parse("content://com.android.badge/badge"),

"setAppBadgeCount", String.valueOf(count), extras);

return true;

} catch (Exception e) {

e.printStackTrace();

return false;

}

private static boolean setOPPOBadge2(int count, Context context) {

try {

Intent intent = new Intent("com.oppo.unsettledevent");

intent.putExtra("packageName", context.getPackageName());

intent.putExtra("number", count);

intent.putExtra("upgradeNumber", count);

PackageManager packageManager = context.getPackageManager();

ListResolveInfo receivers = packageManager.queryBroadcastReceivers(intent, 0);

if (receivers != null receivers.size() 0) {

context.sendBroadcast(intent);

} else {

Bundle extras = new Bundle();

extras.putInt("app_badge_count", count);

context.getContentResolver().call(Uri.parse("content://com.android.badge/badge"),

"setAppBadgeCount", null, extras);

}

return true;

} catch (Exception e) {

e.printStackTrace();

return false;

}

新版本：

新款的OPPO角标功能仅支持内置应用、微信和QQ显示角标，若要使用角标功能，必须提交申请，审核通过了才能开放，官方给的具体审核标准如下：

申请角标接入规则（应用必须适配OPPO手机，保证角标功能测试通过）

a) 系统应用；

b) 国内外各区域用户量排名Top5的三方即时通讯类应用，且只允许显示即时通信消息类通知（如QQ、微信、facebook、line）；

c) OPPO公司内部费商业化及运营性质的办公类型即时通信应用（如Teamtalk）；

d) 国内外邮件类应用（各区域各属于用户量第一梯队的应用）。

vivo：

桌面图标角标”默认关闭，需要用户手动开启。

开启路径：“设置”-“通知与状态栏”-“应用通知管理”-应用名称-“桌面图标角标”。

未成功接入“桌面图标角标”的应用，无“桌面图标角标”选项。

备注：视OS版本差异，“桌面图标角标”名称可能为“应用图标标记”或“桌面角标”。

a. 添加权限：

uses-permission android:name="com.vivo.notification.permission.BADGE_ICON" /

b. 应用在需要显示桌面角标的场景，通过广播将信息发送给vivoLauncher：

广播参数：

action：launcher.action.CHANGE_APPLICATION_NOTIFICATION_NUM

packageName：应用包名

className：主类名

notificationNum：未读消息数目

简单示例：

Intent intent = new Intent();

int missedCalls = 10;

intent.setAction("launcher.action.CHANGE_APPLICATION_NOTIFICATION_NUM");

intent.putExtra("packageName", "com.android.xxxx");

intent.putExtra("className", "com.android.xxxx.Mainxxxx");

intent.putExtra("notificationNum", missedCalls);

intent.addFlags(Intent.FLAG_RECEIVER_INCLUDE_BACKGROUND);

sendBroadcast(intent);

注意：

在8.0上，还需要给Intent加上下面的flag

Intent.FLAG_RECEIVER_INCLUDE_BACKGROUND

sansung：

private static boolean setSamsungBadge(int count, Context context) {

try {

String launcherClassName = getLauncherClassName(context);

if (TextUtils.isEmpty(launcherClassName)) {

return false;

}

Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE");

intent.putExtra("badge_count", count);

intent.putExtra("badge_count_package_name", context.getPackageName());

intent.putExtra("badge_count_class_name", launcherClassName);

context.sendBroadcast(intent);

return true;

} catch (Exception e) {

e.printStackTrace();

return false;

}

android 角标红点怎么设置

角标实现

要实现这个角标：

1、放置一个隐藏的图片在app中，在需要它显示的时候，显示该图片，并以该图片为背景，显示新增消息数；

2、自定义一个控件，用于显示该角标信息。例如，角标相对于控件的位置、底色、数字等；

对比或者使用后，你会发现，自定义一个控件，无疑更符合我们的使用习惯。无需特定的图片，减少了app的大小等，更重要的是，这样方便我们的使用。

在角标实现中，有个开源代码BadgeView写的很符合我们的心理预期。实现了我们常用的所有功能。

BadgeView

这是一个继承TextView控件，自定义而成的一个简单控件。我们通过它，可轻易实现对角标位置、角标底色、角标内容等控制。
