Android系統 小米,三星,索尼手機發送桌面快鍵提醒數字圖標,在Android系統中,衆所周知不支持BadgeNumber,雖然第三方控件BadgeView能夠實現應用內的數字提醒,但對於系統的圖標,特別是app的logo圖標很難實現數字標誌,即便是繪圖的方式不斷修改,但這種方式天生弊端,實用性不好。但幸運的是,某些ROM廠商提供了私有的API,但也帶來了難度,API的不一樣意意味着代碼量的增長和兼容性問題更加突出。css
咱們如今來實現桌面logo或者說icon右上角的圖標,先來看2張圖,第一張來自互聯網,第二張來自我的實踐!(因爲實驗條件有限,只能測試小米的(⊙o⊙)…,有興趣的同窗測試一下其餘的吧) java
好了,上代碼android
public class MainActivity extends Activity { //必須使用,Activity啓動頁 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+"未讀消息"); builder.setTicker("您有"+number+"未讀消息"); 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);// 設置信息數 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以前的版本 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以上版本須要使用通知發送 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);//是否顯示 localIntent.setAction("com.sonyericsson.home.action.UPDATE_BADGE"); localIntent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME",lancherActivityClassName );//啓動頁 localIntent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", number);//數字 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);//數字 localIntent.putExtra("badge_count_package_name", getPackageName());//包名 localIntent.putExtra("badge_count_class_name",lancherActivityClassName ); //啓動頁 sendBroadcast(localIntent); Toast.makeText(this, "Samsumg," + "isSendOk", Toast.LENGTH_LONG).show(); } }
注意lancherActivityClassName 必須被配置爲 啓動頁 android.intent.category.LAUNCHERapp
<activity android:name="com.sample.activites.Welcome" android:configChanges="locale|keyboard|screenSize" android:label="@string/app_name" android:screenOrientation="portrait" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> <intent-filter> <action android:name="android.intent.action.CREATE_SHORTCUT" /> </intent-filter> </activity>
