示例1: hashCode
import java.util.ArrayList; //導入方法依賴的package包/類
@Override
public int hashCode() {
ArrayList<Object> objectList = new ArrayList<>();
for (int i = 0, length = mParamList.size(); i < length; i++) {
objectList.add(mBundle.get(mParamList.get(i)));
}
return objectList.hashCode();
}
示例2: haveContentsChanged
import java.util.ArrayList; //導入方法依賴的package包/類
boolean haveContentsChanged() {
if (!PermissionsUtil.checkAllPermissionsGranted(
mContext, Manifest.permission.READ_CONTACTS)) {
Log.i(TAG, "No permission to read contacts. Marking contacts as not changed.");
return false;
}

if (contactCount > ContactsDictionaryConstants.MAX_CONTACTS_PROVIDER_QUERY_LIMIT) {
// If there are too many contacts then return false. In this rare case it is impossible
// to include all of them anyways and the cost of rebuilding the dictionary is too high.
// TODO: Sort and check only the most recent contacts?
return false;
