Android P Launcher3中添加未读信息角标
Launcher3中添加未读信息角标
添加未读信息部分参考Android之前版本即可
首先在源码中加入对应的监听（公司使用GMS项目，因此修改的是GMS包下的overlay）
vendor/partner_gms/products/gms_overlay/frameworks/base/core/res/res/values/config.xml
-
+
在对应的文件中注释掉Notification的拦截和低内存设备的判定
frameworks/base/services/core/java/com/android/server/notification/NotificationManagerService.java
+ //if (mAllowedManagedServicePackages.test(listener.getPackageName())) {
mConditionProviders.setPackageOrComponentEnabled(listener.flattenToString(),
userId, false, granted);
mListeners.setPackageOrComponentEnabled(listener.flattenToString(),
userId, true, granted);
getContext().sendBroadcastAsUser(new Intent(
NotificationManager.ACTION_NOTIFICATION_POLICY_ACCESS_GRANTED_CHANGED)
.setPackage(listener.getPackageName())
.addFlags(Intent.FLAG_RECEIVER_REGISTERED_ONLY),
UserHandle.of(userId), null);
savePolicyFile();
+ //}
packages/apps/Settings/src/com/android/settings/notification/ZenAccessSettings.java
// if (!ActivityManager.isLowRamDeviceStatic()) {
reloadList();
getContentResolver().registerContentObserver(
Secure.getUriFor(Secure.ENABLED_NOTIFICATION_POLICY_ACCESS_PACKAGES), false,
mObserver);
getContentResolver().registerContentObserver(
Secure.getUriFor(Secure.ENABLED_NOTIFICATION_LISTENERS), false,
mObserver);
// } else {
// setEmptyText(R.string.disabled_low_ram_device);
// }
packages/apps/Settings/src/com/android/settings/utils/ManagedServiceSettings.java
// if (!ActivityManager.isLowRamDeviceStatic()) {
mServiceListing.reload();
mServiceListing.setListening(true);
// } else {
// setEmptyText(R.string.disabled_low_ram_device);
// }
在Launcher3中修改对应文件的函数，使其满足传递对应的未读数量
packages/apps/Launcher3/src/com/android/launcher3/badge/BadgeRenderer.java
public void draw(
- Canvas canvas, int color, Rect iconBounds, float badgeScale, Point spaceForOffset) {
+ Canvas canvas, int color, @Nullable BadgeInfo badgeInfo,
+ Rect iconBounds, float badgeScale, Point spaceForOffset) {
...
+ String notificationCount = badgeInfo == null ? "0"
+ : String.valueOf(badgeInfo.getNotificationCount());
+ int numChars = notificationCount.length();
canvas.save();
+
+ boolean isText = !DOTS_ONLY && badgeInfo != null && badgeInfo.getNotificationCount() != 0;
- mCirclePaint.setColor(Color.BLACK);
- canvas.drawBitmap(mBackgroundWithShadow, mBitmapOffset, mBitmapOffset, mCirclePaint);
- mCirclePaint.setColor(color);
- canvas.drawCircle(0, 0, mCircleRadius, mCirclePaint);
+ if (isText) {
+ mTextPaint.setColor(Color.RED);
+ canvas.drawBitmap(mBackgroundWithShadow, mBitmapOffset,
+ mBitmapOffset, mTextPaint);
+ mTextPaint.setColor(Color.WHITE);
+ canvas.drawText(notificationCount, 0, mTextHeight / 2, mTextPaint);
+ } else {
+ mCirclePaint.setColor(Color.BLACK);
+ canvas.drawBitmap(mBackgroundWithShadow, mBitmapOffset, mBitmapOffset, mCirclePaint);
+ mCirclePaint.setColor(color);
+ canvas.drawCircle(0, 0, mCircleRadius, mCirclePaint);
+ }
将调用BadgeRenderer中draw方法的地方，修改：
packages/apps/Launcher3/src/com/android/launcher3/BubbleTextView.java
- mBadgeRenderer.draw(canvas, mBadgeColor, mTempIconBounds, mBadgeScale,
- mTempSpaceForBadgeOffset);
+ mBadgeRenderer.draw(canvas, mBadgeColor, mBadgeInfo, mTempIconBounds,
+ mBadgeScale, mTempSpaceForBadgeOffset);
packages/apps/Launcher3/src/com/android/launcher3/folder/FolderIcon.java
- mBadgeRenderer.draw(canvas, mBackground.getBadgeColor(), mTempBounds,
- badgeScale, mTempSpaceForBadgeOffset);
+ mBadgeRenderer.draw(canvas, mBackground.getBadgeColor(), mBadgeInfo, mTempBounds,
+ badgeScale, mTempSpaceForBadgeOffset);
注意：FolderBadgeInfo中默认返回的数量为0，需要手动修改
packages/apps/Launcher3/src/com/android/launcher3/badge/FolderBadgeInfo.java
public int getNotificationCount() {
// This forces the folder badge to always show up as a dot.
- return 0;
+ return mNumNotifications;
}
