Android系统 小米/三星/索尼快键图标BadgeNumber数字提醒
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。
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youxia)
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 = ""; } 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) { try { 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-->这种发送必须是miui 6才行 } catch (Exception e) { e.printStackTrace(); //miui 6之前的版本 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); } } 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
<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>
