拨号盘收藏联系人分析(常用联系人&&收藏联系人):
1.[dialer]OldSpeedDialFragment调用onCreateLoader
return ContactTileLoaderFactory.createStrequentPhoneOnlyLoader(getActivity());
2.[dialer]ContactTileLoaderFactory调用(CursorLoader)createStrequentPhoneOnlyLoader
public static CursorLoader createFrequentLoader(Context context) {
return new CursorLoader(context, Contacts.CONTENT_FREQUENT_URI, COLUMNS,
Contacts.STARRED +"=?", new String[]{"0"}, null);//收藏联系人字段STARRED
}
3.[framework/base]CursorLoader调用-> ForceLoadContentObserver();
4.[OldSpeedDialFragment]
@Override public void onLoadFinished(Loader loader, Cursor data) {
mContactTileAdapter.setContactCursor(data);//调用PhoneFavoritesTileAdapter->setContactCursor
setEmptyViewVisibility(mContactTileAdapter.getCount() == 0);
}
5.[dialer]PhoneFavoritesTileAdapter
void setContactCursor(Cursor cursor) {
if (!mDelayCursorUpdates && cursor != null && !cursor.isClosed()) {
mNumStarred = getNumStarredContacts(cursor);
if (mAwaitingRemove) {
mDataSetChangedListener.cacheOffsetsForDatasetChange();
}
saveNumFrequentsFromCursor(cursor);
saveCursorToCache(cursor);
// cause a refresh of any views that rely on this data
notifyDataSetChanged();
// about to start redraw
mDataSetChangedListener.onDataSetChangedForAnimation();
}
}
如有错误请帮忙指出,谢谢!
